In the corporate setting, if an employee creates a copyrightable work within the scope of his or her employment, the Copyright Act not only grants ownership of the work to the employer but actually considers the employer the “author” of the work. By contrast, under the Patent Act, one who creates an invention is its inventor, and ownership will only pass to another, including an employer, through a written assignment. In other words, unless there is an agreement to the contrary, an employer does not have any rights in an invention “which is the original conception of the employee alone.” Given the close relationship between copyright law and patent law, it is puzzling that employees’ works and inventions would be treated so differently under the two disciplines. Yet, when one considers their historical foundation, it becomes clear that there were pivotal differences between the needs of the two disciplines in the nineteenth century that led to their modern formulations. In particular, whereas the type of copyrightable works created in the nineteenth century transitioned from individual labors to collaborative labors among multiple individuals working together, which necessitated the collecting of rights in order to make use of the resulting copyrightable work, patentable inventions continued to be perceived during the nineteenth century as the work of individuals. Moreover, patent law developed other, more limited doctrines that provided some rights to inventors’ employers. Today, however, most patentable inventions are invented by multiple inventors in a collaborative environment. In fact between 1885 and 1950, the percentage of U.S. patents issued to corporations grew from 12% to at least 75%. These numbers have only continued to increase in the past decade. Moreover, the recently passed Leahy-Smith America Invents Act partially recognizes this change by permitting an “applicant for patent” to file a “substitute statement” instead of an inventor’s oath or declaration in certain circumstances. Nevertheless, patent law remains stuck in the past. The failure to modernize how patent law handles employee invention has led to a string of significant court opinions, including from the Supreme Court and the Federal Circuit, holding that employers had not received adequate assignments to their employees’ patented inventions and thus could not bring suit based thereon. In order to resolve these issues and bring patent law into the twenty-first century, the Patent Act should be amended to borrow from the Copyright Act and adopt a principle similar to the work made for hire doctrine that would grant employers the rights to their employees’ inventions made within the scope of their employment. This article proceeds in four parts. Part I discusses the current state of copyright and patent law vis-à-vis employers’ rights in their employees’ intellectual labor. This part will compare copyright’s work made for hire doctrine to three patent law doctrines: the shop rights doctrine; the hired-to-invent doctrine, and the employee improvements doctrine. Part II describes the evolution of copyright law during the nineteenth century from the former regime, which vested employees with presumptive ownership of their work, to the current regime, which grants employers presumptive rights to their employees’ efforts. Part III describes patent law during the time that copyright law was changing so dramatically—including the development of the patent law doctrines described in Part I—and posits potential reasons that patent law did not make a similar move. In particular, (a) patent law’s development of the doctrines described in Part I provided similar benefits, although in the form of different rights, to those provided by copyright law’s work made for hire doctrine, and (b) the perceived nature of invention in the nineteenth century did not call for a unification and codification of those doctrines the way copyright law’s did. Finally, Part IV argues that patent law should modernize and develop an “inventions made for hire” doctrine.  Section A discusses the copyright law doctrine of work made for hire and its benefits for employers. Section B discusses doctrines that provide some of those benefits in patent law.  However, “author” is a term of art with meaning beyond the creator of or “person who originates or gives existence” to a work. In particular, where a “work made for hire”—another term of art—is concerned, the employer is “considered the author” unless the parties agree otherwise. A work may be considered made for hire if (1) it was prepared within the scope of an employee’s employment, or (2) it is a certain type of commissioned work and the parties have so agreed previously. Whether the creator of a copyrightable work is an employee for purposes of the work made for hire doctrine is determined by looking to the common law doctrine of agency. In Community for Creative Non-Violence v. Reid, the Supreme Court identified thirteen factors that it considered relevant to whether an individual was considered an employee as a matter of agency law. The Supreme Court declared that “[n]o one of these factors [was] determinative,” but at least one circuit has held that not all factors are created equal and some will be important in “virtually every situation” while others “will often have little or no significance.” The more important factors are to be given “more weight in the analysis.” Once a work is considered made for hire, the employing or commissioning party enjoys several benefits over a work that is not considered made for hire, but rather is transferred to the employing party. First, unlike in patent law, it immediately becomes the owner of a legal right to the work. In patent law, an inventor must first file an application with the United States Patent and Trademark Office (“PTO”), which is then examined by a PTO employee to determine if the alleged new invention is entitled to a patent. Copyrights, on the other hand, vest immediately once an original work of authorship is fixed in a tangible medium of expression. For a company to gain an ownership interest in a copyrighted work not made for hire, the interest must be negotiated for and transferred in a signed written document. When a work qualifying as a work made for hire is created, however, no negotiation or written instrument is required for that specific work because, for copyright purposes, as long as agency would hold that the work’s creator was an employee working within the scope of his employment, his employer is considered the work’s author. There are two subsidiary benefits to the immediate grant to the employer of a work’s copyrights. First, no court intervention is required to transfer the rights. As will be described below, in certain cases, patent law will grant employers rights in their employee’s patents, but to vest those rights the employee must still sign a document transferring ownership to his employer. If he refuses, a court order may substitute for the transfer. Second, the work made for hire doctrine allows a grant of rights without needing to define what is being granted. Whereas when a grant of rights is negotiated, the transferor may come back to the transferee to argue about which rights were actually transferred and the scope of the intended transfer. Second, an employer holding the rights in a work made for hire may register the work in the Copyright Office in its own name. This is an optional but important step, because without registration a copyright infringement action may not be initiated, and generally, statutory damages are not available for infringements prior to registration. Third, the work made for hire doctrine grants employers all of the rights associated with copyright ownership. Thus, they can exclude others from using the work, and leverage that right to extract rents in exchange for a license authorizing someone else to use the work. Further, employers using works made for hire are authorized to then transfer their ownership of the works’ copyrights to another party, either in whole or in part. They can also, of course, exercise any of the rights authorized under the Copyright Act itself, including creating derivative works. One set of rights an employer is not granted under the Copyright Act, however, is the right to attribution and integrity granted for works of visual art. Fourth, the work made for hire doctrine also protects employers from future rights granted to authors. For example, the Copyright Act of 1976 granted authors the right to terminate transfers, but those new rights did not apply to creators of works made for hire because their employers were considered the author. In addition, after the 1976 revisions, employers remained shielded from the exercise of the transfer termination provisions because no transfer is considered to have taken place under the work made for hire doctrine; the employer was the work’s original “author.” Fifth, the work made for hire doctrine grants employers certainty with regard to the duration of their copyrights. Works not made for hire subsist for the life of the author plus 70 years. This means that those to whom the original author transfers must know the duration of the original author’s lifetime in order to calculate the duration of the copyrighted work’s term. Works made for hire, however, are merely granted a term of 95 years from publication or 120 years from creation, whichever expires first. This time frame serves two functions. First, it simplifies the requirements of an employer to keep track of the duration of its copyrights. Second—grim though it may be—if the employee were to die within 25 years of publication or 50 years of creation, the employer would benefit from a longer copyright term than if the work were considered made for hire. Finally, the work made for hire doctrine applies to all works universally, regardless of the type of work or the employee’s level of contribution. In other words, a work created and conceptualized entirely by only one employee is treated the same as a work created by hundreds of employees, each of whom contributed minor improvements and expression to the work.  (2) grant of title without transfer/assignment; (3) grant of title without court intervention; (4) registrability in the employer’s own name; (5) exclusion of others from using the work and licensing rights in the work to others; (6) use of the work; (7) transfer of title to others; (8) protection from future rights granted to work’s creator; (9) shield from transfer termination; (10) benefits with regard to copyright term duration; and (11) universal application regardless of level of contribution.
It is immediately apparent that the benefits of the termination shield and duration are not relevant to patent law because patents are granted for a set term of years—whether the base of 20 years or an extended term due to regulatory or PTO review—not tied to the inventor’s lifetime. Therefore, there would be no special duration benefits should an inventor’s employer be considered an “inventor” for purposes of the Patent Act. In addition, unlike copyright transfers, which as discussed above may be terminated upon notice, patent assignments are not subject to termination. The other benefits, however, require additional consideration. The three following sections describe modern patent law doctrines that give employers some, but not all, of the benefits of copyright law’s work made for hire doctrine.  However, because patent law describes negative rights, it is a protection against infringement actions by the employee patent holder and her assigns, and not an affirmative grant of use of the patented invention. Shop rights arise when an employee, “during his hours of employment, [and] working with his [employer’s] materials and appliances, conceives and perfects an invention for which he obtains a patent.” The courts have held that in such circumstances, the employee by force of law must give his employer a nonexclusive, royalty-free right to practice the invention. The doctrinal basis behind the shop right remains fuzzy, as courts have described it being based on (a) a license implied in fact, (b) estoppel, and (c) equity and fairness. Shop rights do not have the same scope as work made for hire, however. A shop right is not an ownership interest in the patent, which means that an employer does not have either the right to exclude others by threatening to sue for infringement or the right to file a patent application. Similarly, a shop right is non-exclusive, which means that the employee patent holder is free to assign rights to others by granting them a patent license. In addition, a shop right is not transferable other than with the sale of the entire appurtenant business.
 Just as in the work made for hire context, courts have established a number of factors to indicate whether an inventor has been hired to invent. However, unlike work made for hire, the hired-to-invent doctrine requires the employee to assign any patent obtained; it does not vest title immediately in the employer upon invention. Although, failure to assign after a court order to do so may result in the order having the same effect as an assignment. At first blush, this patent law doctrine would appear to accomplish much of what the copyright law work made for hire doctrine does. However, there are differences. First, work made for hire vests title in an employer immediately. The hired-to-invent doctrine merely obligates the inventor to assign the invention to his or her employer. True, no negotiation is required after the inventive activity occurs, but until an assignment is signed, the invention’s creator continues to hold the patent on the invention—albeit in trust for his employer. Furthermore, if the invention’s creator refuses to assign his patent rights, then a court order is required. Second, the doctrine is only effective against employees who are actually hired to invent. Employees who create an invention within the scope of their employment but who were not specifically directed to do so retain their patent rights. Third, unlike the work made for hire doctrine, which permits an employer to file a copyright registration in its own name, the hired-to-invent doctrine still requires the patent application to be filed in the inventor’s name, even if the employer, as assignee, files a patent application on his behalf. Finally, as the employee is still considered the “inventor” under the Patent Act, it is possible for future rights to be given to the “inventor” that would not be automatically vested in the inventor’s employer. For example, in the copyright context, when the right to terminate transfers of ownership was introduced as a right of “authors,” it did not apply to those whose works were made for hire, as their employers were considered the “authors.” Similar rights could be granted to “inventors” that would affect the assignees of the inventors’ patent rights.
 Under this doctrine, when an employer conceives of an invention, but receives ancillary suggestions or improvements from his employee, he retains all rights in the invention, including any employee improvements. To qualify under the employee improvements doctrine, the employer must have had a “plan and preconceived design,” and the improver must be an employee. The employee improvements doctrine provides a minimal step toward the work made for hire doctrine, but does not come anywhere close to providing a substitute. First, the doctrine still requires there to be an inventor. All the doctrine does is subsume improvements by another person into the inventive exercise of the employing inventor; it does not operate to grant an employing corporation rights. In addition, the improvements that are granted must be ancillary, so any benefits from the doctrine will be minimal. Thus, if the employee creates a non-ancillary invention or improvement, the employer still needs to qualify under one of the previous doctrines or negotiate an assignment. At base, the employee improvements doctrine determines whether an employee should be considered a joint inventor or not, which does not come close to achieving the same benefits of the work made for hire doctrine.
Given that patent law never developed a doctrine that defaulted patent rights to an employer the way copyright law did, one is left to wonder why. Why is it that copyright law in the nineteenth century began to apply an employer presumption? And why did the courts not feel the need to apply a similar presumption in patent cases? Part II discusses the development of the work made for hire doctrine in the nineteenth century, and Part III discusses potential reasons that a similar doctrine was not developed in patent law.  Professor Catherine L. Fisk has claimed that the doctrine “neither was invented by the drafters of the 1909 Act, nor was it well recognized in the cases before 1909.” Instead, between the American Civil War and the passage of the Copyright Act of 1909 the default rule in copyright cases quietly switched from employee ownership to employer ownership. Professor Fisk argues that this move was justified by “cloaking” artists in an “aura of . . . romantic genius” to argue for greater legal protection, while simultaneously “downplaying or ignoring individual creative genius so as to assert corporate ownership over those copyrighted works.”  In the early days of copyright, protection was of limited application. The first copyright act—the Copyright Act of 1790—only protected maps, charts, and books. Among the books that received copyright protection were the books in which court decisions were reported. Thus, it was only natural for the first copyright cases concerning employment to involve books containing those decisions and the authors that authored them. In the first case involving an employed author, the author of twelve volumes reporting the caselaw of the United States Supreme Court assigned his copyrights to a publisher. The publisher then sued a subsequent case reporter for copyright infringement because he had produced a volume titled “Condensed Reports of Cases in the Supreme Court of the United States,” which included the work of the prior reporter. The Supreme Court, noting that the original reporter had failed to satisfy the formality requirements, held that it could not confer common law copyright on the initial reporter. However, what is telling about the opinion is that it appears to assume that the original reporter—and not the publisher—would be entitled to the copyrights in his work, even though his status as an employee was uncertain at best. Later cases in the antebellum era involved school books, theatrical works, and cartography. What is particularly interesting about this period of time is the courts’ clear pro-employee stance. In later decades, courts’ rhetoric would be inconsistent with the holdings of their decisions. While courts would claim to celebrate the genius and romanticism of the independent author, they would simultaneously grant first publishing houses and later employers the rights to that labor. During the antebellum nineteenth century, however, courts’ rhetoric praising the individual was consistent with the holdings of their decisions, which largely gave employees ownership of the copyrights in their works. The only cases where employers were held to have been granted copyrights in their employees’ works involved expressed contracts and cartography which, by its very nature, requires coordination among various individuals. True, smaller scale maps could be created by one person on their own, but for anything of a greater scale, coordination among various parties would be required.  In the postbellum period, like the antebellum period, the relevant cases generally involved legal publications, as well as theatrical works. One of the theatrical work cases is particularly important for the purposes of this article. In Keene v. Wheatley, the court ruled against the plaintiff-employer on many of her arguments, but with regard to ownership of one of her employee’s works, the court stated:
Moreover, as recent cases make clear, companies cannot rely on the patent law doctrines and contracts with their employees to ensure ownership of the rights to their employees’ inventions. For example, the Supreme Court recently held that although an inventor working as a research fellow at Stanford University signed a Copyright and Patent Agreement that stated that he “‘agree[d] to assign’ to Stanford his ‘right, title and interest in’ inventions resulting from his employment at the University” and written assignments of rights, which Stanford used to file several patent applications, Stanford did not receive the inventor’s patent rights because he signed a Visitor’s Confidentiality Agreement that provided that he “‘will assign and do[es] hereby assign’ to Cetus his ‘right, title and interest in each of the ideas, inventions and improvements’ made ‘as a consequence of [his] access’ to Cetus” between signing the CPA and the assignments. Further, many modern employers intend to license, rather than use, their employees’ inventions, which a shop right would not permit. Similarly, in Abbott Point of Care Inc. v. Epocal Inc., Abbott filed a patent infringement suit against Epocal, a competitor in the diagnostic field, alleging infringement of patents that “cover systems and devices for testing blood samples,” Epocal, however, was founded by Dr. Imants Lauks, the named inventor of the patents at issue and a former employee of Abbott’s predecessors. Despite the fact that Dr. Lauks had entered into two employment agreements, one of which contained a provision requiring him to assign all of his rights to any inventions that he might conceive, the Federal Circuit determined that Abbot did not hold rights to the patents and, thus, lacked standing to bring the lawsuit. The court determined that Dr. Lauks had resigned from his previous employment in 1999, and that while the consulting agreement that he entered into after his resignation stated that various provisions of Dr. Lauks’ employment agreement remained in effect, it did not address invention assignments or obligations. Thus, the two patent applications Dr. Lauks filed after entering into the consulting agreement did not belong to Abbot. Additionally, despite the high assignment rate discussed above, when a patent assignment is found to be ineffective, the consequences can be extreme. This is particularly true where the employer acts on its belief that an assignment is effective and incurs costs associated with the patented technology, only to learn that they do not, in fact, hold any patent rights. As such, it is time for patent law to come to terms with the fact that it is stuck in the past and adopt an inventions made for hire doctrine. To do so, Congress need only pass an act amending two sections of the Patent Act. First, Congress would add a subsection (c) to 35 U.S.C. § 111 as follows:
|Table 1: Work Made For Hire Benefits|
|No Assignment from Employee|

Here, [the employee], while in the general theatrical employment of the [employer], engaged in the particular office of assisting in the adaptation of this play; and made the additions in question in the course of his willing performance of this duty. [The employer] consequently became the proprietor of them as products of his intellectual exertion in a particular service in her employment.For this proposition, the court did not rely on copyright law. Instead, the court looked to patent law, and determined that since “[w]here an inventor, in the course of his experimental essays, employs an assistant who suggests, and adapts, a subordinate improvement, it is, in law, an incident, or part, of the employer’s main invention,” the plaintiff in Keene was entitled to the “literary proprietorship” of her employee’s work. In the eyes of the Keene court, the employee was merely adding minor enhancements akin to the patent doctrine of employee improvement. Yet, over time the doctrine of work made for hire found increasing judicial support and eventually became a default rule in favor of employers. Over the next several years, this new doctrine was mentioned in dicta, but in no case did a court rule that an employer possessed rights over its employee by virtue of the default rule. Instead, the presumption was switched surreptitiously. In Callaghan v. Myers, for example, while holding that a court reporter-employee held the copyrights in his work instead of his government employer, the Supreme Court determined that this was the case only due to “a tacit assent by the government to his exercising such privilege,” This shift in emphasis made employer ownership a presumption that was only rebutted by tacit agreements and expressed contracts. Why did the courts make this shift? Professor Fisk posits three potential factors:
 Courts might have felt that a default rule of employer ownership was more likely to reflect the intent of most parties and wanted to save the parties the trouble of negotiating for employer ownership. . . .  [C]ourts might have begun to see employers as possessing a stronger moral claim and believed that any employee who planned to assert copyright ownership ought to be forced to disclose that intent and negotiate for it. . . .  [A]s changing assumptions about the nature of authorship strengthened the rhetorical force of the employer’s claim, a default rule of employer ownership might have seemed more intrinsically appealing, irrespective of whether the parties might negotiate around it.In response to the shifting sands of copyright law doctrine of the nineteenth century, one might expect that parties would have begun contracting around the default rules, but two factors may have made contracting prohibitively difficult:
First, the costs of transacting might be high when the parties have to discuss something as touchy as authorship. Employers might have been afraid to alienate employees by demanding assignment of the copyright, preferring to run the risk of litigation later. Employees may have lacked legal sophistication to realize that it was necessary to contract for copyright ownership. Second, the instability of the law may have made enforcement of any contract they did reach highly uncertain.In any case, by the nineteenth century, the work made for hire doctrine was in the wind, whether because of changes in the parties themselves, or merely the impressions of those sitting on the bench.  It was at this time that the legal fiction arose that a corporation could be an author. This idea makes sense when viewed one way: corporations are merely collections of individuals working toward, generally, hierarchically determined joint goals. However, it flies in the face of the entire notion of the individual romantic author. The concept behind the expression embodied in a copyrightable work can be created by any number of different people as it moves through the corporate process. This is particularly clear today when one looks at the large corporations behind music, television, and film. These corporations are made up of hundreds of thousands of employees, and even more independent contractors. To produce one blockbuster film may require hiring and coordinating thousands of individuals, each of whom may contribute to a portion of the film. Without the work made for hire doctrine, these companies would have to rely on a messy web of contracts and the employee improvements doctrine, and even then, it is unlikely that they would be assured that all the relevant rights had been secured. By 1899, however, the courts had come to realize the need for a doctrine that allowed corporate employers to control the copyrights in the works of their employees by default. In Collier Engineer Co. v. United Correspondence Schools, a salaried employee hired “to compile, prepare, and revise . . . instruction and question papers” had moved to a new employer and prepared similar materials. His former employer made a motion for a preliminary injunction, which the court denied, but in so doing determined that the employer was entitled to any copyright in the original materials. This idea of protecting employers when their employees move to other employers will resurface in Part III as a justification for employer ownership of patent rights. Later cases embraced the idea that when an employer hired individuals to produce copyrightable works, the copyrights in those works were granted to the employer. In this way, by the turn of the century, copyright law and patent law had developed fairly parallel doctrines with regard to employee works and inventions. In 1909, however, the Copyright Act was revised to codify the work made for hire doctrine by adding the following language:
[T]he word ‘author’ shall include an employer in the case of works made for hire.By including employers of those that create works made for hire within the definition of the term “author,” Congress continued in the direction the courts had been heading, but went farther by creating an explicit employer presumption. Professor Fisk identifies three reasons for this change: (1) an ease in drafting the Act, (2) avoiding constitutionality challenges, and (3) ensuring that copyright ownership would vest initially in employers so they could benefit from copyright renewals. And that, ladies and gentlemen, was history. Since 1909, work made for hire has remained a mainstay of American copyright law. Yet, despite over one hundred years of the work made for hire doctrine in copyright law, patent law remains based on the rule that only the individuals that create an invention can be considered inventors. Moreover, for an employer to claim patent rights, he must either negotiate an assignment, or rely on one of the doctrines discussed in Part I.B.: shop rights, hired-to-invent, or employee improvements. Barring one of these options, an employer holds no rights in a patent absent a written assignment. Part III will explore the patent cases of the late nineteenth century, and posit potential reasons that patent law did not take a similar route.  However, at the end of eighteenth century, there were “probably no more than 300 people who we would now class as scientists in the entire world,” By 1800, there were about a thousand, and by 1900 there were approximately 100,000. Due to the growth in the number of scientists, science began to shift from “a gentlemanly hobby, where the interests and abilities of a single individual [could] have a profound impact, to a well-populated profession, where progress depend[ed] on the work of many individuals who [were], to some extent, interchangeable.” Similarly, the number of non-scientist inventors blossomed throughout the nineteenth century leading to an increased ability to appreciate the “interplay between science and technology, particularly in the fields of electricity and engine building,” which “led to a host of new practical machines that changed communications, transportation, the home, the workplace, and the farm,” For example, at the beginning of the nineteenth century, America remained a nation of farmers who used the same hand implements that had been used for centuries to harvest their crops and who would travel primarily by horse or boat. In the time before the Civil War, however, non-scientist inventors made many advances, including the invention of the steamboat, farming machinery, the telegraph, and synthetic materials. Such advances were only possible due to the increased interplay between science and technology that continued to grow throughout the nineteenth century. These developments also led to societal changes, including increased prosperity and the end of slavery as new equipment was developed that could perform the work better and more cheaply. Despite the democratization of science and invention in the nineteenth century, however, inventive activity continued to be considered the work of individuals. In fact, there are “no reported cases before 1843 in which an employer claimed, as against an employee, ownership of a patent because the inventor had been working for him at the time of the invention,” Thus, in the nineteenth century, the general perception was that inventorship was the work of certain individuals, who were considered the great men of the time. One visual example of this mentality is Christian Schussele’s 1857 painting titled Men of Progress, which depicts Benjamin Franklin overlooking nineteen nineteenth century inventors: Despite this public perception, however, the reality was that even these great men had assistance in creating their famous inventions. Among those depicted in Schussele’s painting is Charles Goodyear, who is remembered for his invention of vulcanized rubber in 1839. He received a patent on his process in 1844, and almost immediately became embroiled in patent litigation. Not only was Goodyear forced to litigate against his competitors, however, but also against his own employees, one of whom attempted to patent one of Goodyear’s inventions. Fortunately for Goodyear, despite recognizing a presumption in favor of the employee—who actually made the machine—the courts considered Goodyear’s employee’s activities to have been at Goodyear’s direction, and thus, they determined that it was Goodyear, and not his employee, that was the true inventor. Despite the favorable result for Goodyear, the case only underscored the presumption that employees owned their inventions, as the court continued to articulate employee-ownership as the general presumption in such cases. Thus, time and time again, courts were required to find exceptions in order to protect employers from the presumption’s consequences. For example, in 1843 the Supreme Court, in McClurg v. Kingsland, determined that a license or grant from the employee to the employer may be presumed by virtue of the fact that the employee:
was employed by the defendants . . . receiving wages from them by the week; while so employed, he claimed to have invented the improvement patented, and after unsuccessful experiments made a successful one . . . the experiments were made in the [employer’s] foundry, and wholly at their expense, while [the employee] was receiving his wages, which were increased on account of the useful result.This implied license, or shop right, prevented the assignees of the employee’s patent from bringing suit against the former employer for infringement when all the employer was doing was continuing to use the process it had been using prior to the employee’s departure. The Court reached this result without requiring an assignment of the patent. Rather, the Court held that the plaintiffs took their assignment from the employee subject to his license to his former employer. As such, McClurg is generally thought of as the first shop rights case. It can also be seen as a fairly pro-employee case, for the employer received no rights to the invention other than the right to use it despite the fact that the employee would not have been able to make his improvement but for his employer’s time, money and equipment. During this same time period, other inventors were creating major innovations in both science and industry. For example, in 1844 Samuel Morse—also depicted in Men of Progress—connected the first intercity line between Washington and Baltimore and sent the message, “What hath God wrought!” Moreover, scientists were making significant advances in electric theory, evolution, and thermodynamics. Similarly, in the decade that followed, solo inventors continued to be credited with major breakthroughs in both science and industry. For example, during the 1850s, Heinrich Geissler is credited with the leaps forward that resulted in the invention of the vacuum tube. Further, the 1850s saw huge advances in telecommunications technology, including Morse’s testing of the first transatlantic telegraph cable. Even Abraham Lincoln took the time to consider the discoveries, inventions and improvements that resulted from America’s willingness to observe, reflect and experiment. Despite the attribution of these major advances to individual inventors, the reality was that even in the 1840s, teams of workers were working together to develop new technologies, which “somewhat undermine[s] the heroic mythology surrounding the great individualistic and entrepreneurial American inventors,” The dichotomy between the myth of the sole inventor and the reality that inventive activity was being carried out by groups of individuals in many ways mirrors the shift that was occurring in copyright law at that time. However, instead of acknowledging that multiple individuals were involved in the inventive process, courts turned a blind eye to the significant contributions employees were making to their employers’ inventions and dismissed those contributions as small modifications. In King v. Gedney, for example, the court disregarded the following evidence as “vague and equivocal,” and instead determined that the employer “might have” given the employee—a draftsmen and general foreman—general directions about the improvement:
[The employee] was the foreman, and directed the making the alterations in the factory. [The employer] gave him no directions in relation to those alterations; [another employee] asked him for directions during the time that he was making alternations, and his answer was, ‘I do not know anything about it; go to [the employee].’ He said it was [the employee’s] improvement, and he knew nothing about it; if it did not work it was [the employee’s] fault; [the other employee] must go to him for all instructions. [The other employee] did not hear [the employer] give directions to any of the workmen in the shop. He has seen [the employer] and [the employee] conversing together at the factory, when chalk marks were made upon the floor by [the employee] to convey to [the employer] the manner in which he was going to prosecute the work.The court determined that if the general idea was the employing inventor’s, then the employee “could only be considered as acting as [his] servant,” and held the employer to be the original and sole inventor. Thus, by crediting employers with being sole inventors, courts were able to continue to articulate the presumption that those who do the actual inventing will own the rights to their inventions. However, as employees became more and more involved with the inventive process, courts would find it increasingly difficult to rely on the employee improvements doctrine to rebut the presumption of employee ownership.  Similarly, in the mid-1860s, scientists were making major advances in chemistry and thermodynamics. Then, in 1865, George Westinghouse received his first patent for a rotary steam engine, followed by patents for railroad frogs and air brakes. A few years later, a “self-taught practical innovator” by the name of Thomas Alva Edison would apply for his first patent. Edison is a particularly interesting example of a nineteenth century inventor, because it is well documented that he “regularly employed not only mechanics and craftsmen but also college-trained chemists and engineers in his invention workshop,” In some ways, then, it is not surprising that the Supreme Court first recognized the employee improvements doctrine in its 1868 Agawam Co. v. Jordan opinion. In Agawam, an inventor named John Goulding hired a blacksmith, Edward Winslow, to help in his machine shop. Goulding had been working on his invention and was at the point of experimentation when Winslow, having visited another factory, made a suggestion of replacing a piece of Goulding’s invention with a spool and drum. Goulding went back and forth about the value of the suggestion, but after making another modification to make the change practicable, he adopted Winslow’s suggestion. The new invention was patented and eventually assigned to the plaintiff who then sued the Agawam Woolen Company for infringement. Agawam defended, in part, by arguing that it was Winslow, and not Goulding, that invented the improvements for which the patent was granted. The Court held that Goulding’s claim to invention of the patent was sustained, because all that Agawam could prove was that Winslow suggested the spool and drum—an “auxiliary” part of the invention. In handing another victory to an employer, however, the Court continued to recite that the general presumption is that employees hold rights to their inventions. Similarly, as discussed above, during this time employers in copyright cases began to see the presumption switch from employee ownership to employer ownership. For example, five years prior to Agawam, the influential case of Kenne v. Wheatley was decided in favor of the employer relying on an employee improvements-type argument to grant a theater proprietor the copyrights to a play adapted by her and her theatrical company. Whereas in theater it was undeniable that multiple individuals were required to develop new materials and produce it for the stage, invention in the 1870s continued to be perceived as the work of individuals with minimal help from employees instructed to carryout manual labor. Significant changes, however, were on the horizon for those industries that employed workers to design and construct their products. The “United States began to develop a single price and market system,” which led to capital intensive industries that “employed workers who owned no tools and had few skills, leading to social inequalities that created new political crises,” Those inequities led to the formation of labor unions, which employed a variety of tactics to effect the status of workers in this country. “The decades from the 1870s through the early 20th century saw one disruptive strike after another and the beginning of the appeal of ideologies and reform strategies that would characterize the labor movement—agrarian reform, populism, socialism, anarchism, and progressive reformism.” Despite these changes, inventive activity in the United States soldiered on. For example, Edison—who, as discussed above, employed a variety of workers in his invention workshop—had filed for patents on 21 inventions by 1871. As inventive activity began to involve more complex technology, the proportion of inventions devised by solo inventors continued to decline. Perhaps in recognition of these changes, the Supreme Court began to hint at a willingness to recognize employers’ ownership of patented inventions that they hired employees to create. Nevertheless, there were limits to the Court’s willingness to grant patent rights to one who employed another to invent. In Collar Co. v. Van Dusen, for example, the Supreme Court determined that the plaintiff, despite employing a set of paper-makers to create a paper collar that would be perceived as a real starched linen collar, was not entitled to a patent because only the paper-makers had invented something patentable. The plaintiff had argued that the paper-makers had received inspiration and direction, but the Court determined that the paper-markers had provided the whole improvement and therefore the plaintiff had no rights to their invention under Agawam’s ancillary discoveries rule. Despite its use of the terms “employer” and “employee,” however, the Collar case is better understood as concerning, using our modern parlance, independent contractors, who, even if Collar was a modern copyright case, would be unlikely to fall within the work made for hire doctrine. Rather than inspiring and directing the paper-makers’ improvement, the patentee derived all of the improvements he attempted to patent from the paper-makers. Similarly, other courts in the 1870s held that if an employee’s invention was outside the employee’s inventive arena, the employer would receive no more than a shop right to the invention. By the 1880s, “farmers and industrial workers represented a force for political insurgency that began to coalesce into new movements that threatened to change the nature of society,” These movements reflected a general anti-monopoly and big business sentiment at the turn of the century, as they began to lead to discussions of new government regulations “to control railroad rates and other large enterprises . . . to address the growing power of bankers and railroad magnates,” At the same time, entrepreneur inventors, like Westinghouse, were beginning to build empires of their own from their own companies and inventions, as well as those of others. These companies employed various individuals who developed patentable inventions during their employment. During the remainder of the nineteenth century, disputes over employees’ inventions became more frequent and led to cases that further developed the shop right and employee improvements doctrines. The courts, however, failed to develop a mechanism for dealing with employees that were explicitly hired to invent, until the hired-to-invent doctrine was formally recognized by the Supreme Court in 1924. Also, the rise of the corporate form introduced additional complications, such as whether a shop right could be assigned. Despite these developments, however, in not one of these cases was an employing company considered an “inventor” by virtue of its employees’ activity. Rather, for a company to receive patent ownership, an employee needed to assign it his or her rights. By the turn of the century, each and every person in the United States had been affected by the inventions of the nineteenth century. In particular, the poor were being put to work in factories using newly invented machinery and tools. Even the middle classes indirectly benefited from the benefits of the day:
For the middle classes, such as physicians, attorneys, engineers, academics, journalists, and managers, whose employment was less dependent on machinery and tools than on their education, the new technologies provided new sources of entertainment, comfort, and opportunities. By 1890, a person who worked in such a profession could come home, switch on the electric light, make a phone call, go to the refrigerator and take out a cold beer, light a factory-made cigarette with a safety match, then sit down to listen to a phonograph record while reading a newspaper with news of the day from all over the planet. It was a new world, for none of those experiences had been possible 40 years earlier, even to the wealthy. Yet, despite the fact that today the “ordinary inventor is . . . a joint inventor who invents as part of a team,” patent law continues to require that corporate employers receive assignments from their employees in order to effect a transfer of the ownership of the employees’ patent rights. In Part II, several reasons behind copyright law’s move toward the work made for hire doctrine were posited: (1) courts were attempting to reflect the intent of the parties; (2) courts felt that employees were in the best position to determine ex ante whether they intended to assert copyright ownership; (3) changing notions of the nature of authorship; (4) ease of statutory drafting; (5) avoiding constitutional concerns; and (6) concern about renewal terms. Three of these reasons simply do not apply to patent law. First, patents in the United States do not have renewal terms. Second, the copyright statute was being revised in 1909 for reasons beyond the codification of the work made for hire doctrine. The patent statute, by contrast, was not significantly revised until 1952. Without an independent push to redraft the Patent Act, the need to ease statutory drafting was absent, and constitutional concerns in granting patent rights to non-“inventors” would not need to be addressed. As for the remaining reasons for the shift in copyright law, patent law simply did not share those factors. First, the perceived nature of inventive activity in the nineteenth century did not lend itself to an argument for the need of a doctrine like work made for hire. As discussed in Part II, copyrighted works grew in complexity over the course of the nineteenth century. While copyrighted works were originally only embodied in single author books, they steadily grew to include complicated works involving the input of the multiple creative individuals. In particular, the creation of maps and theatrical works required coordination among multiple parties to insure that works could be exploited. Once the 1909 Act was passed, that complication grew exponentially as additional works were brought under the copyright statute. The perception of inventive activity in the nineteenth century, on the other hand, did not appear to require significant coordination among parties. Rather, credit for advances was given to individual inventors, whether or not they, like Edison, employed others in their invention workshops. Moreover, even in the nineteenth century, most patents were on incremental improvements of existing technologies, which made it even more likely that the number of individuals involved in each inventive push forward would be small. Further, even if an invention required multiple individuals to reduce it to practice, the individual credited with the invention could subsume any other inventive activity into his invention under the employee improvements doctrine. In fact, in 1916, three-quarters of U.S. patents were issued to individuals. Thus, the need to coordinate among multiple individuals that existed in copyright law in the nineteenth century did not exist in patent law. Second, the existing doctrines that had developed, including the hired-to-invent doctrine, provided sufficient ex ante protection to employers. The shop rights doctrine, which was well established in the early part of the century, provided employers with a way of ensuring that their expectations were met. Unlike today where many organizations that own patent rights merely license those rights to others to use, in the nineteenth century, most companies used patent rights merely to exclude competitors while they themselves developed products to sell to consumers. Without the need to license, companies merely needed the right to use, which the shop rights doctrine provided. Moreover, as described above, when an inventor did use assistance in the process of developing his invention, the employee improvements doctrine protected him from needing to secure rights from each assistant in his workshop. As long as the inventor couldn’t be seen as deriving his invention from someone else, he could be fairly content that his rights in the invention would be secure. Finally, by the end of the nineteenth century, employers were securing contracts with their employees that included provisions requiring the assignment of any patented inventions later developed. In 1885, only 12% of U.S. patents were issued to corporations. By 1950, it had grown to 75%, and by the 1980s, 84% of U.S. patents were assigned to corporations, “usually the employer of the actual inventor,” In the past decade, those efforts have become increasingly successful. In fact, it will come as no surprise that the Intellectual Property Owners Association’s list of top patent owners does not include the name of a single individual. Further, by the turn of the century, when an employer hired an inventor, the hired-to-invent doctrine would require the inventor to assign their rights to the employer. Despite the protection of the existing patent law doctrines that give employers some of the benefits of the work made for hire doctrine, it is clear from Table 5 that not one doctrine captures all of the benefits from that doctrine:
|Table 5: Work Made For Hire Benefits v. Patent Doctrines|
|Shop Rights||Hired-to-Invent||Employee Improv.|
|No Assignment from Employee||✓||✓|
|No Court Intervention||✓||✓|
|Exclusion and Licensing||✓||✓|
|Transfer to Others||✓||✓|
|Protection from Future Rights|
(c) In the case of an invention made for hire, the employer is considered the inventor for purposes of this title, and, unless the parties have expressly agreed otherwise in a written instrument signed by them, owns all patents rights to the invention.Second, Congress would add a subsection (f) to 35 U.S.C. § 100 as follows:
(f) An “invention made for hire” is an invention invented or discovered by an employee within the scope of his or her employment.Whether an individual is an employee for purposes of the invention made for hire doctrine will be determined by looking to the same common law doctrine of agency that the Supreme Court identified in Community for Creative Non-Violence v. Reid. Moreover, there is over two decades of caselaw interpreting agency doctrine in light of the Copyright Act and over a century of caselaw interpreting the work made for hire doctrine for courts to rely on in implementing this new provision.
 See Copyright Act of 1976, 17 U.S.C. § 201(b) (2006) (“In the case of a work made for hire, the employer or other person for whom the work was prepared is considered the author for purposes of this title, and, unless the parties have expressly agreed otherwise in a written instrument signed by them, owns all of the rights comprised in the copyright.”).
 See United States v. Dubilier Condenser Corp., 289 U.S. 178, 188 (1933) (noting that invention is “the product of original thought”); Solomons v. United States, 137 U.S. 342, 346 (1890) (“[W]hatever invention [an inventor] may thus conceive and perfect is his individual property.”); Gayler v. Wilder, 51 U.S. 477, 493 (1851) (“[T]he discoverer of a new and useful improvement is vested by law with an inchoate right to its exclusive use, which he may perfect and make absolute by proceeding in the manner which the law requires.”); 8 Chisum on Patents § 22.01 (2012) (“The presumptive owner of the property right in a patentable invention is the single human inventor . . . .”); see also Patent Act of 1952, 35 U.S.C. § 152 (2006) (“Patents may be granted to the assignee of the inventor of record in the Patent and Trademark Office, upon the application made and the specification sworn to by the inventor, except as otherwise provided in this title.”); id. § 261 (“Applications for patent, patents, or any interest therein, shall be assignable in law by an instrument in writing.”); Bd. of Trustees Trs. of Leland Stanford Junior Univ. v. Roche Molecular Sys., Inc., 131 S. Ct. 2188, 2192 (2011) (“Since 1790, the patent law has operated on the premise that rights in an invention belong to the inventor.”); Dubilier Condenser, 289 U.S. at 187 (“A patent is property and title to it can pass only by assignment.”); 8 Chisum on Patents § 22.01 (2012) (“The inventor . . . [may] transfer ownership interests by written assignment to anyone . . . .”). In fact, only the actual inventor is entitled to a patent, and only the inventor or someone he has assigned his patent rights to in writing may file a patent application, which in either case must be made on the inventor’s behalf. See 35 U.S.C. § 111(a)(2)(C) (“Such application shall include . . . an oath by the applicant as prescribed by section 115 of this title.”); id. § 115 (“The applicant shall make oath that he believes himself to be the original and first inventor of the process, machine, manufacture, or composition of matter, or improvement thereof, for which he solicits a patent . . . .”) (emphasis added); id. § 118 (“Whenever an inventor refuses to execute an application for patent, or cannot be found or reached after diligent effort, a person to whom the inventor has assigned or agreed in writing to assign the invention or who otherwise shows sufficient proprietary interest in the matter justifying such action, may make application for patent on behalf of and as agent for the inventor . . . and the Director may grant a patent to such inventor . . . .”) (emphasis added).
 Dubilier Condenser, 289 U.S. at 189; see also Stanford, 131 S. Ct. at 2196 (“We have rejected the idea that mere employment is sufficient to vest title to an employee’s invention in the employer.”).
 Certainly copyrights and patents share an affinity due to their finding support in the same clause of the Constitution. U.S. Const. art. I, § 8, cl. 8 (“The Congress shall have Power . . . [t]o promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries . . . .”).
 As described below, in the nineteenth century, copyright law had a strong presumption of employee ownership, which slowly moved to an employer presumption that was finally codified in the twentieth century. See infra Part II. Patent law, on the other hand, developed various doctrines that permitted employers to be considered the owners of patent rights in certain circumstances, but not in others. See infra Part III.

 Patent law and copyright law borrowing from each other is nothing new. The Supreme Court borrowed patent law’s construction of secondary liability to inform its copyright decision in Sony Corp. of America v. Universal City Studios. 464 U.S. 417, 439 (1984) (“There is no precedent in the law of copyright for the imposition of vicarious liability on such a theory. The closest analogy is provided by the patent law cases to which it is appropriate to refer because of the historic kinship between patent law and copyright law.”). That analysis was then expounded on in the copyright case of Metro-Goldwyn-Mayer Studios, Inc. v. Grokster, Ltd., 545 U.S. 913 (2005), and then the copyright focused construction was used as precedent in later patent cases. See, e.g., Ricoh Co. v. Quanta Computer Inc., 550 F.3d 1325, 1336–40 (Fed. Cir. 2008) (citing Sony and Grokster to determine the standard for contributory infringement); DSU Med. Corp. v. JMS Co., 471 F.3d 1293, 1303–04 (Fed. Cir. 2006) (same).

 For example, in 2009, the founders of Skype, after selling the company to eBay, sued their former company and eBay for copyright infringement because, although eBay had purchased the good will in Skype, they had only licensed the source code to the program.

 On the other hand, a long-lived author could result in a significantly longer period of protection.
 By avoiding negotiation, parties also avoid the possibility that a court would interpret contract terms later in a way that the original parties to the agreement would not have anticipated. See, e.g., Marvel Characters, Inc. v. Simon, 310 F.3d 280 (2d Cir. 2002) (holding that although both parties had signed a settlement agreement stipulating that a work was made for hire, the provision was ineffective because it was signed subsequent to the work’s creation with purported retroactive effect).
 An additional societal benefit might include the idea that the work made for hire doctrine may permit and even incentivize the creation of works that would be impossible to create if the employing company had to negotiate with each employed author.

Supp. at 697 (“[The employer] has the right to use the plaintiff’s invention but pays no royalties to the patentee. It has no property or title interest in the invention or the patent. [It] has no exclusive contract with the [employee] that others shall not practice the invention. At most [it] has a ‘shop right’ or license to use, manufacture and sell the [product] which is not an exclusive contract and amounts to a bare license protecting [the employer] from a claim of infringement by [the employee]. . . . Such a licensee may neither sue alone nor join with the licensor patentee in an infringement action.”) (citations omitted).

Locke, 150 U.S. 193 (1893) (holding that the Hapgood doctrine would not be extended to a company that “was organized upon the same basis as the [predecessor company]; that the business of the company was to be the same as that carried on by [the predecessor], and to be carried on in the same premises; that the entire property and assets of the firm and its liabilities and obligations were devolved upon the [successor] company”); Hapgood v. Hewitt, 119 U.S. 226 (1886) (holding that although after the original corporation entitled to a shop right dissolved, the stockholders had created a new corporation—its successor in interest—the shop right did not cover the new corporation).
 See Standard Parts Co. v. Peck, 264 U.S. 52 (1924) (holding that the invention’s creator held the legal title to the patented invention in trust for his former employer, and ordering him to assign the title in the patent to him employer’s successor); see also Houghton v. United States, 23 F.2d 386 (4th Cir. 1928) (“An employ[ee], performing all the duties assigned to him in his department of service, may exercise his inventive faculties in any direction he chooses, with the assurance that whatever invention he may thus conceive and perfect is his individual property. . . . But this general rule is subject to these limitations. If one is employed to devise or perfect an instrument, or a means for accomplishing a prescribed result, he cannot, after successfully accomplishing the work for which he was employed, plead title thereto as against his employer. That which he has been employed and paid to accomplish becomes, when accomplished, the property of his employer. Whatever rights as an individual he may have had in and to his inventive powers, and that which they are able to accomplish, he has sold in advance to his employer.” (citing Solomons v. United States, 137 U.S. 342, 346 (1890)); Nat’l Dev. Co. v. Gray, 55 N.E.2d 783, 787 (Mass. 1944) (“If the employee fails to reach his goal the loss falls upon the employer, but if he succeeds in accomplishing the prescribed result then the invention belongs to the employer even though the terms of employment contain no express provision dealing with the ownership of whatever inventions may be developed.”).
 Chisum, supra note 3, at § 22.03 (“The primary factor . . . is the specificity of the task assigned to the employee. . . . Evidentiary factors that carry some weight include (1) previous assignments of patents on other inventions by the employee; (2) a customary practice within the company for other similarly situated employees to assign; (3) whether the invention was conceived during the period of employment; (4) who originally posed the problem solved by the invention; (5) the employee’s authority within the company to determine to whom to give a problem for solution; (6) the relative importance of the idea to the employer’s business; (7) a previous inconsistent position on inventorship by the employer; (8) an agreement by the employer to pay royalties to the employee; (9) payment of patent procurement expenses by the employer or employee; and (10) the absence of initial interest by the employer when the employee first exposed the idea.”).
 See Standard Parts, 264 U.S. at 56–57 (Upholding the district court’s formal decree that the patentee, “within ten days from the date of the decree, assign and transfer to the company the legal title to the letters patent, and also transfer to it all other patents or pending applications for patents for inventions made by him, in connection with the processes and machinery developed in the performance of the agreement with the [company],” Furthermore, “if [the patentee] failed to perform the decree, ‘then and in that event’ the ‘decree [would] have the same force and effect as such assignments and transfers would have had if made.’”).

 Id. at 7 (“[S]ome courts did focus on the employer’s contribution or the employer’s right to control. But over time many came to rely simply on the legal fiction that employment renders the employer the author. The ‘crude legal fiction’ was not that the employer’s right to control made it the author; it was that the employer was the author.”).

 Copyright Act of 1790, ch. 15 §1, 1 Stat. 124 (amended 1976). The first thing you notice in this group of works is that while books can certainly be created by an individual author, the most useful maps require coordinated effort by multiple individuals.
 See Wheaton v. Peters, 33 U.S. 591 (1834) (holding that the author of twelve volumes reporting the cases of the United States Supreme Court held copyright in his original elements added to the reports, although not the work of the justices themselves).
 See Fisk, supra note 64, at 16–18 (discussing early American legal publishing and the status of legal reporters, who were hired by the courts as independent contractors—although not called that—and encouraged to find publishers for their work by selling their copyrights). Fisk believes that the fact that early cases involved case reporters who, like Wheaton vis-à-vis the United States Supreme Court, had relationships with the judges likely deciding these cases, likely influenced their outcome. See id. at 21. The reporters were not traditional employees, but rather important and well-educated men who had agreed to perform a function that that was essential to the profession. See id.

 Id. Although the court ultimately held that the employee’s work was not copyrightable, the court did determine that equitable principles permitted the plaintiff to recover based on the employee’s giving his work to the defendants to add to their production. Id. at 188.
 Professor Fisk makes much of the fact that the doctrine “slipped into the cases without the usual adversary process,” because in both Keene and Lawrence, the employees did not lose the rights to their work. Fisk, supra note 64, at 43–44. In Keene, the employee had already assigned whatever he had to the theater producer defendants; if anyone was going to lose out it would have been them. Keene v. Wheatley, 14 F. Cas. 180 (C.C.E.D. Pa. 1861). In Lawrence, despite the court acknowledging a copyright interest in the employer, the parties’ express contract protected the employee. Lawrence v.

 In Aalmuhammed v. Lee, the plaintiff was hired to work on, without a written agreement, and made “very extensive” contributions to the film Malcolm X. 202 F.3d 1227, 1229 (9th Cir. 2000). However, the Ninth Circuit held that in the same way that the person who controlled the film’s hue was not a joint author of the film, the plaintiff would not be considered one either. Id. at 1233. Instead, the “superintended” or “master mind” of the whole work—in this case Spike Lee, who had signed a work for hire agreement—would be considered the work’s author. Id. at 1233, 1235. To have held otherwise would have opened authors to claims by “research assistants, editors, and former spouses, lovers and friends,” not to mention dramaturgies, actors, cinematographers, film editors, art directors, and costume, makeup, set and sound designers.

The court denied the motion because it was unclear whether the newly created pamphlets infringed because both sets of pamphlets were compilations. Id.
 See Edward Thompson, 119 F. at 219 (In response to the defendant’s demurrer that the plaintiff corporation was not the copyright holder, the court stated, “It sufficiently appears that complainant’s publication is the result of the intellectual labor of the editors and compilers employed by complainant.

Second, it avoided constitutional doubts about a default rule of employer ownership stemming from the constitutional provision that Congress may give “authors” a copyright. Third, and most importantly, the drafters of the revision wanted to be sure that the employer would be the initial copyright owner rather than an assignee, because only the initial owner is entitled to obtain a renewal.”) (citations omitted).

With the extreme heat of the stove, the gum should have melted. Instead of softening, however, Goodyear’s newest rubber charred like leather. It could still stretch but it wasn’t soft or sticky! Goodyear noticed that the edge of his sample was perfectly cured and not charred. If he could find the correct temperature, he could make fully cured rubber.”).

 In Warner v. Goodyear, Charles Goodyear patented an invention and then Solomon C. Warner, who had been employed as a machinist for Goodyear, attempted to patent the same invention. 29 F. Cas. 256, 256 (C.C.D.C. 1846). The invention at issue was a combination for “manufacturing corrugated or shirred India-rubber goods” using “metallic calendar rollers an elastic endless apron and a stretching-frame,” Id.
 The patent commissioner refused Warner’s patent, and when he appealed, the court found that although an inference could be drawn for Warner because he made the machine, it was rebutted by his employment and that while still employed he “stood by and saw Mr. Goodyear apply for and obtain a patent for it without objection,” Id. at 257. Moreover, the court found a presumption in Goodyear’s favor:
from the fact that Warner made the machine for Goodyear at his request, for his benefit, and at his expense, [the presumption] is that it was made according to his directions; and the burden of proof is then on Warner to show that the machine was not according to his directions.Id. The court went on to find that Goodyear had conducted a number of experiments and that Warner had merely reduced to practice Goodyear’s combination. Id. Furthermore, the court may have been swayed by some evidence of bad faith, as Wilson did not apply for a patent for 18 months, six months after Goodyear had obtained his patent, and had reached an agreement with another company to pay for the costs in getting the patent.

he made no demand on theme for any compensation for using his improvement, nor gave them any notice not to use it, till, on some misunderstanding on another subject, he gave them such notice, about the time of his leaving their foundry, and after making the agreement with the plaintiffs, who owned [another] foundry . . . for an assignment to them of his right.Id.
 Id. at 204. The patent had been granted on an “improvement in the mode of casting chilled rollers and other metallic cylinders and cones . . . [so that] iron rollers or cylinders could be so cast that when the metal was introduced into the mould it should cause a sw[i]rl or rotary motion, by which the flog or dross would be thrown into the centre instead of the surface of the cylinder,” Id. The improvement was to change the direction of a tube exiting a furnace and entering the cylindrical mold from a perpendicular position to an angular one. Id. at 204–05 (“The tube or tubes, or passages called gates, through which the metal to be conveyed into the moulds shall not enter the mould perpendicularly at the bottom, but slanting, or in a direction approaching to a tangent of the cylinder, or if the gates enter the moulds horizontally or nearly so, shall not enter in the direction of the axis of the cylinder, but in a tangent form, or inclining towards a tangent of the cylinder.”).

 Interestingly, McClurg has reasserted itself in modern copyright law to establish the idea that legislative expansion of intellectual property rights does not conflict with the constitution’s requirement that copyrights and patents be only for “limited times,” See Golan v. Holder, 132 S. Ct. 873, 886–87 (2012). (“This Court again upheld Congress’ restoration of an invention to protected status in McClurg v. Kingsland . . . . There we enforced an 1839 amendment that recognized a patent on an invention despite its prior use by the inventor’s employer. Absent such dispensation, the employer’s use would have rendered the invention unpatentable, and therefore open to exploitation without the inventor’s leave.”) (citations omitted); Eldred v. Ashcroft, 537 U.S. 186, 187–88 (2003); Golan v. Ashcroft, 310 F. Supp. 2d 1215, 1219 (D. Colo. 2004) (“As explained in Eldred, the McClurg court determined that [the employee] was ‘unprotected under the law in force when the patent issued because he had allowed his [ex-]employer briefly to practice the invention before he obtained the patent. Only upon enactment, two years later, of an exemption for such allowances did the patent become valid, retroactive to the time it issued.’ The McClurg Court upheld retroactive application of the new amended laws ‘for though they may be retrospective in their operation, that is not a sound objection to their validity.’”) (citations omitted).

Bartlett, 31 N.W. 747, 752 (Wis. 1887) (“The mere fact that, in making the invention, an employe [sic] uses the materials of his employer, and is aided by the services and suggestions of his co-employes [sic] and employer in perfecting and bringing the same into successful use, is insufficient to preclude him from all right thereto as an inventor.”).

 For example, in Wellman v. Blood, an employer attempted to patent an invention, and an interference party argued that he was not the inventor, but rather the inventor was a man who had created a drawing of the invention with a modification of his own. 29 F. Cas. 628, 629–31 (C.C.D.C. 1856) (involving improved machinery for “cleaning top cards of carding machines”). The court determined, however, that
[i]f the employer conceives the result embraced in the invention, or the general idea of a machine upon a particular principle, and in order to carry his conception into effect, it is necessary to employ manual dexterity, or even inventive skill, in the mechanical details and arrangements requisite for carrying out the original conception; in such cases the employer will be the inventor, and the servant will be a mere instrument through which he realizes his idea.Id. at 631. It went on to decide that Wellman had conceived of the improvement first and “practically reduced it,” even though the final invention included the employee’s small modification. Id.

 Id. at 587.
 Id. at 588, 593. Interestingly, Goulding actually failed to apply for a renewal of his patent right due to “erroneous information given him by the Commissioner of Patents,” and the patent expired. Id. at 588, 594. Twenty-one years after the patent expired, Goulding persuaded Congress to pass a special act, authorizing the patents commissioner to entertain an application for extension, and the patent reissued. Id. at 588, 594; see also An Act for the Relief of John Goulding, ch. 88, 12 Stat. 904 (1862). In a previous case involving Goulding’s patent, the constitutionality of the grant was questioned, but the circuit court rejected the argument. Jordan v. Donson, 13 F. Cas. 1092, 1095–96 (C.C.E.D. Pa. 1870).
 Agawam, 74 U.S. at 589, 595.
 Agawam, 74 U.S. at 605–07. In so holding, the Court repeated over and over that while only the inventor is entitled to a patent, if he employed other persons to help and they made “valuable discoveries ancillary” to the employer’s plan, the employer who invented the original idea is regarded as the owner of them. Id. at 602–03. Rather, the employee’s contribution would need to meet the derivation requirements to preempt the employer’s rights from vesting. Id. (citing various derivation cases, including Pitts v. Hall, 19 F. Cas. 754 (C.C.N.D.N.Y. 1851); Reed v. Cutter, 20 F. Cas. 435 (C.C.D. Mass. 1841); Alden v. Dewey, 1 F. Cas. 329 (C.C.D. Mass. 1840)).

 Noonan, supra note 90, at 74. By 1872, “Edison had filed patents for 52 inventions, most of them on printing-telegraph improvements. In the next three years, Edison created inventions such as the electric pen and mimeograph for making copies of letters and the quadruplex telegraph. The quadruplex handled two messages simultaneously to and from each end of the telegraph line, making a total of four messages on a single wire,” Id.
 Fisk, supra note 99, at 1141 (citing B. Zorina Khan & Kenneth L. Sokoloff, “Schemes of Practical Utility”: Entrepreneurship and Innovation Among “Great Inventors” in the United States, 1790–1865, 53 J. Econ. Hist. 289, 295–301 (1993) and Naomi R.

 See United States v. Burns, 79 U.S. 246, 252 (1871) (hinting at the hired-to-invent doctrine in dicta).
 90 U.S. 530, 536, 564 (1874). Andrew Evans had previously received a patent for an improvement in the creation of shirt collars, which turned out to be a flop. Id. The shirt collars were “made of parchment-paper and coated with varnish of bleached shellac,” which—according to the reporter—evidently did not look like linen, much less starched linen, became discolored over time, emitted an odor when wearers sweated, and was not amenable to the new fashion of turned down collars. Id. at 537. So Evans employed Crane & Co. to create “something which while it was paper and could be produced cheaply should yet have such a thickness, tenacity, pliability united with strength, and have moreover that polish of surface, and that exact bluish tint which is found in the best starched linen—as distinguished from yellowness and from dead white—which would deceive even critical observers who had no opportunity of judging otherwise than by eye,” Id. Crane & Co. after laborious effort were able to create just such a collar, and after it was created, Evans assigned his patent rights to the Union Paper Collar Company and they applied for and received a reissue of the patent. Id. at 537, 539. Collar Co. then brought suit against Van Dusen.
 Id. at 550, 564 (“[P]ersons employed, as much as employers, are entitled to their own independent inventions, and if the suggestions communicated constitute the whole substance of the improvement the rule is otherwise, and the patent, if granted to the employer, is invalid, because the real invention or discovery belongs to the person who made the suggestions.”). The court first noted that Evans likely knew nothing about the process of manufacturing paper and that the original patent did not describe the process added in the reissue. Id. at 561. It then found that Evans “did not communicate any information to [Crane & Co.] respecting the process by which such paper could be produced, nor did he give [them] any directions upon the subject,” because without knowledge of making paper he was unable to do so. Id. at 562.
 See Whiting v. Graves, 3 Ban. & A. 222 (C.C.D. Mass. 1878). In Whiting, an employer hired a machinist to maintain the machines in his new dry goods factors and to make any other machinery that would be necessary, but did not include a provision in his service contract related to patents. Id. at 223. Instead, the employer would have the machinist assign his inventions prior to application for patents on them, which worked fine for the employer’s dry goods machines, but then the machinist made an improvement on sewing-machines. Id. The court determined that while the employer would be afforded a shop right in the machinist’s inventions by virtue of his original contract, an additional assignment would be required for the employer to take legal title. Id. at 224. The court went on to hold, based on various testimony, that the employer was only entitled to a one-half interest in the patents, by virtue of an agreement to pay the patent expenses for one-half of the profits from the manufacture of the invention, and that the machinist was entitled to assign his interests to the defendants, which meant they could not infringe. Id. at 1061; see also Niagara Radiator Co. v. Meyers, 40 N.Y.S. 572, 573–76 (N.Y.S. Ct. 1896) (finding machine shop foreman not hired to invent); Connelly Mfg. Co v. Wattles, 23 A. 123, 124 (1891) (finding a shop foreman would not be hired to invent).

 Noonan, supra note 90, at 60 (“By the 1880s, Westinghouse was involved in several enterprises. As well as companies and patents he originated on his own, he also started purchasing the companies and patents of others, too. He seemed to find opportunities everywhere.”).
 See Clark v. Fernoline Chem. Co., 5 N.Y.S. 190, 191 (N.Y. Sup. Ct. 1889) (In a case primarily concerned with a dispute over unpaid wages, the New York Superior Court held that although an employee had been hired as a chemical expert and chemist, his employer was only entitled to a shop right and not an assignment of any patents granted to the employee.); see also Gill v. United States, 160 U.S. 426 (1896) (holding that the patentee had acquiesced to the government’s use of his invention—a shop right); McAleer v. United States, 150 U.S. 424, 432 (1893) (finding an expressed contract permitting government use); Lane & Brodley Co. v. Locke, 150 U.S. 193, 196, 198–99 (1893) (finding implied license—or shop right—from inventor to partnership, which was incorporated while he was still working there); Solomons v. United States, 137 U.S. 342, 346–48 (1890) (finding an implied license permitting government use—a shop right). In Dalzell v. Dueber Watch Case Manufacturing Co., an individual, who had been employed at various times within a company as an electroplater, slider and toolmaker, invented various things and applied for and was granted patents on them. 149 U.S. 315, 315–19 (1893) (the inventions involved improvement in the making of watch case cores). The employee sued the employer fro infringement, and the employer responded by seeking specific performance of an oral agreement to assign the right to obtain patents on them. Id. at 317–20. The Court held that an oral agreement for the “assignment of the right to obtain a patent for an invention” was neither within the statute of frauds nor covered by the requirements that all patent assignments be in writing. Id. at 320. However, the Court determined that the testimony was in hopeless conflict and therefore refused to afford specific performance; thus, allowing the infringement action to proceed. Id. at 326. The Court did, however, leave open the possibility that a shop right had been granted. Id. (“It is proper to add that the question whether the [employer], by virtue of the relations and transactions between it and [the employee], had the right, as by an implied license, to use [the employee’s] patents in its establishment is not presented by either of these records, but may be raised in the further proceedings upon the bill against the [employer] for an infringement.”).
 See Eclipse Mfg. Co. v. Adkins, 44 F. 280, 281–82 (C.C.N.D. Ill. 1890) (determining that employer who came up with the idea of putting ornamenting on radiator pipes, but had his employees create the design and build the pipes, was entitled to his patent, as the patent was on the idea, not the specific ornamentation); Streat v. White, 35 F. 426, 426, 428 (C.C.S.D.N.Y. 1888) (involving a design patent for textiles intended to be employed to create imitation “seersucker” fabrics, the court determined that because the plaintiff only had the idea of imitation seersucker, which did not constitute a novel idea, and employed a cotton goods factory manager to produce it by whatever means were necessary, he could not patent the resulting design). In Streat, the factory manager and the designer “were furnished a sample of a seersucker, and with a photographic copy of the sample, and where told to imitate it, and that the way in which the imitation was to be effected was left with the designer, who was solely responsible for a successful result, and to whom the task of finding an idea or conception of the method of imitating the crinkle was solely committed,” Id. at 428; see also Streat v. Simpson, 53 F. 358, 359 (C.C.S.D.N.Y. 1893) (finding in a subsequent infringement suit that the plaintiff “had nothing to do about designing or engraving the tools for printing the imitation, but through [the factory manager]; and that the designer and engraver were controlled by anything but the sample and photograph given to them by [the factory manager] is not made to appear”).
 Compare Dalzell, 149 U.S. at 320 (“[A] manufacturing corporation which has employed a skilled workman, for a state compensation, to take charge of its works, and to devote his time and services to devising and making improvements in articles there manufactured, is not entitled to a conveyance of patents obtained for inventions made by him while so employed, in the absence of express agreement to that effect.”) with Solomons, 137 U.S. at 346 (1890) (stating in dicta that “[i]f one is employed to devise or perfect an instrument, or a means for accomplishing a prescribed result, he cannot, after successfully accomplishing the work for which he was employed, plead title thereto as against his employer. That which he has been employed and paid to accomplish becomes, when accomplished, the property of his employer. Whatever rights as an individual he may have had in and to his inventive powers, and that which they are able to accomplish, he has sold in advance to his employer.”); Annin v. Wren, 44 Hun. 352, 353 (N. Y. Sup. Ct. 2d Dept. 1887) (holding that equity required a skilled draughtsman—hired by an iron truck and wheelbarrow manufacturer to develop his business—to assign his patents on improvements to the manufacturer’s wheelbarrows and trucks to the manufacturer if they were based on their joint development, because it would be unreasonable to prevent an employer from using improvements made during the course of the draughtsman’s employment). The court’s decision in Annin may have been colored by the fact that the draughtsman assigned his patent application to his brother in order to deprive the manufacturer of it. Id. at 354.

Tomlins, Law, Labor, and Ideology in the Early American Republic 259 (Cambridge Univ. Press 1993) (“By midcentury, on and off the farm, it seems likely that the proportion of productively engaged Americans employed by others—about one-third in 1820—had increased to about one-half.”).
 It cannot. See Hapgood v. Hewitt, 119 U.S. 226 (1886). In Hapgood, a mechanical expert had been hired by a corporation as vice president, and later superintendent, to create plows and other goods, and to supervise generally the manufacturing department. Id. at 229. While in the corporation’s employ, the expert was asked with creating an iron plow similar to the company’s existing wooden ones, and he did so within the corporation’s employ, during working hours, using employees and corporate materials. Id. at 230. While he was inventing these plows, he never claimed a property ownership, but when he left he made his own, patented the improvements, and sought money from the corporation for its use of the improvements. Id. at 232. The Court held that he was not required to assign his patent to the corporation, but the corporation had received a “naked license to make and sell the patented improvement,” Id. at 233. However, the corporation had, in the meantime, dissolved and the stockholders had created a new corporation, which was its successor in interest; the Court held that the new corporation did not benefit from the shop right. Id. at 232–34. Nevertheless, in Lane & Bodley Co. v. Locke, the Supreme Court determined that a shop right created during a partnership carried over after incorporation, because of the close affinity between the two corporate entities and because the inventor had ratified the transfer by acknowledging the incorporated entity was the successor to the partnership. 150 U.S. at 196.
