While the high cost of prescription drugs is often attributed to strong patent protections and special forms of market exclusivity granted to new small molecule drugs and biologics, there is another factor that explains high prices: the law of trademark and trade dress. Prescription drugs are not just introduced into the market after regulatory approval; they are released with special shapes, colors, packaging, logos, and comprehensive promotional campaigns. After their patent and exclusivity terms end, generic manufacturers, which may produce the medicines at 95% or less of the original retail price, may sell generic versions of the therapeutic compounds but may not sell them with the same appearance as the original medicines. The result is patient confusion, higher costs, and less adherence to drug regimens for the nearly two-thirds of U.S. adults who need prescription drugs. This Article analyzes the effect of trademark and trade dress law on prescription drug prices and recommends both regulatory and judicial approaches that may reduce the threat current law poses to individual and public health.
On July 9, 2021, U.S. President Joe Biden signed an executive order directing the U.S. Food and Drug Administration (FDA) to facilitate the approval for, and importation of, cheaper prescription drugs, but this order did not address one of the most important sources of high drug prices: appearance.1 “More than 131 million people — 66 percent of all adults in the United States — use prescription drugs.”2 For millions of elderly individuals and those suffering from chronic conditions, they are an essential aspect of maintaining health. Access to those medications is affected by cost, and in that respect, conversations about prescription drugs frequently involve the role of patents as part of the reason prescription drug prices in the United States are so high.3 This Article places the law of trademark and trade dress on equal footing with patents and regulatory market exclusivities in the broader conversation on prescription drug prices so that policymakers, physicians, pharmacists, and other stakeholders will address the law of medicine appearance as well as other forms of market protection.4 The recommendations contained below would stand even in the face of, or complementary to, other market exclusivity reforms.
Consider an elderly patient who is prescribed a drug regimen that begins with a bright green pill that is protected by patents, market exclusivity, as well as careful product design by its original manufacturer. After the patent and market exclusivity terms end, state law requires that the medicine be substituted by a cheaper generic version. The elderly patient, used to seeing the bright green pill, now sees a pill that is smaller and has a blue tinge. Believing that there is a mistake—perhaps the wrong medicine was put into the bottle—the patient stops taking the medication until she can speak with her doctor. After several weeks, the patient is convinced the change will not harm her health. Assume then, two weeks later, the pharmacy switches to a different generic supplier, whose pills again appear different. The medicine, dosage, strength, frequency, and all other relevant medical factors are unchanged, but the patient now believes, again, that there is a systematic error in the medical supply chain and stops taking the medicine again. All of this occurs because trademark and trade dress law prohibit the generic manufacturers from using the same pill appearance.
This scenario is routine, not exceptional. In one study, about half of patients (51%) reported receiving a prescription refill in which their pills’ appearance changed in the last year and, of those patients, about half (53%) reported that it happened two or more times.5 The relationship between patients and their medicines is deeply affected by how they appear (inside and outside packaging): their color, shape, hue, imprints, size, texture, and coating.6 Patients taking generic versions of the same medication receive pills of different sizes, shapes, and colors routinely because of trade dress protections, and those changes, alterations, and adjustments, in turn, often adversely affect their adherence to their prescription schedules and trust in the medicines they need.7
The importance of drug products’ appearance is well recognized in the industry: pharmaceutical firms invest as much or more in color, name, shape, and related branding and marketing features as they do in the development of the active pharmaceutical ingredients that actually treat disease and illness.8 For the most part, those investments are not protected by patents. They are protected by the law of trademark and trade dress. And those laws, in turn, do more than just raise the cost of prescription drugs. They shape patient adherence to prescription drug regimens; cause or ameliorate the possibility of medication error; and play a complex role in the division of responsibility between licensing authorities, primarily the FDA and the U.S. Patent and Trademark Office (USPTO).9
Medicines may be protected by a patent as to the small molecule structure of the active compound, while the color, shape, and appearance of a capsule that contains the medicine may be protected by trademarks. Information accompanying the product may be protected by copyright.10 Other aspects of production and advertising may be protected by trade secrets.11 All of these intellectual property protections affect cost most straightforwardly, but other aspects of patient welfare and provider knowledge as well.
This Article sheds light upon the substantial costs that trademark and trade dress impose on patients and emphasizes that, in the broader context of scrutinizing the relationship between intellectual property and high drug prices, patents and regulatory exclusivities are only a piece of a more complicated puzzle.12 In highlighting trademark and trade dress, this Article endeavors to single out that form of intellectual property protection for special scrutiny by legislators, regulators, and judges.
Intellectual property, generally, is controversial.13 On the one hand, each of the traditional forms of protection—copyrights, patents, and trademarks—involve giving an individual or a firm the right to exclude others and, in many cases, charge high prices for products.14 Especially in the context of copyright and trademark, the intellectual property right burdens the use of words, information, and data that may be important for communication, learning, and expression.15 On the other hand, those intellectual property rights provide incentives to create and invent.
These controversies play out vividly in the context of medicines16 and remain the subject of heated debate.17 Broadly speaking, disputes over the intellectual property protections afforded to pharmaceutical companies tend to focus on patents and market exclusivities given pursuant to the generation of data used to support regulatory approval.18 These incentives, the companies argue, encourage continuous innovation.19 Critics argue that the incentives do precisely the opposite: they encourage investment in incremental changes that just barely qualify for costly patent protection, keeping drug prices high and imposing significant barriers to entry for other manufacturers.20
Leaving to one side the acrimonious debate over the incentives that the regulatory state might extend to promote the optimal investment in the right number and variety of biomedical innovations, the reality is that trademark and trade dress are unique.21 The product distinguishing rationale that purportedly justifies trademark and trade dress law arguably does precisely the opposite in the prescription drug context. 22
This Article analyzes the protections that trademark and trade dress afford pharmaceutical companies outside of patents and regulatory exclusivities, which are generally placed at the center of pharmaceutical pricing and policy debates.23 Quite apart from price, patients and their supporters use color, shape, logo, hue, size, and appearance—the classic areas of trademark and trade dress protection—to ensure that they are taking the correct medications, in the prescribed amounts, and at the right times to maintain their health, treat disease, and avoid adverse interactions between medications if they are taking more than one.24 The Article identifies the specific individual and public health problems posed by trademark and trade dress protection and recommends changes in current law that may contribute toward the difficult question of balance that pervades all scholarship on the advantages and disadvantages of using intellectual property protection to promote innovation.25 In the context of pharmaceutical trademarks and trade dress, this means understanding when allowing pharmaceutical firms to protect trademarks and trade dress is too costly relative to the value in having patients adhere to their prescribed medical regimens, avoid medication error, and place trust in their providers and their medicines.
Part I situates trademark and trade dress protections for pharmaceuticals in the broader context of intellectual property protections, which (the Articles argues) overemphasize patents and regulatory exclusivities and underemphasize trademark and trade dress. Part II analyzes the specific costs that current trademark and trade dress law impose on patients as they attempt to adhere to their prescription drug regimens, as well as the costs imposed on physicians as they attempt to help their patients do so. Part III details the legislative, regulatory, and judicial possibilities for addressing the costs that trademark and trade dress impose on patient and physician populations. The Article then provides a brief conclusion.
From the manufacturer’s perspective, planning the intellectual property protections for pharmaceuticals entails careful analysis of product features, the probability of inadvertent or uncontrollable disclosure, and the chemical or biochemical character. Although patents are generally regarded as the foundational and most important protection, they are of limited duration, may be costly to enforce, and are expensive to obtain ex ante.26 Trademark protections, by contrast, are potentially indefinite and may guard significant aspects of a drug’s value even after a patent term expires.
This Part describes the varying forms of intellectual property that explain the high costs of prescription drugs in the United States. It concludes with the specific kinds of protection that trademark and trade dress afford, and how those protections are indefinite so that even when other forms of intellectual property expire, trademark and trade dress still keep generic manufacturers from providing prescription drugs with all the precise attributes of the original medicine.
For small molecule drugs, patent protections cover a 20-year period, generally shortened by the time of disclosure to the time of regulatory approval.27 By international treaty, the 20-year patent term is largely universal, but conditions for granting patents vary by country, and individual countries may allow non-patent forms of regulatory exclusivity.28 For example, in the United States, regulatory exclusivities may generally offer 6-month, 3-, 5-, 7-, and (for biologics) 12-year protections, depending on approval channel and characterization.29 These exclusivity periods allow pharmaceutical manufacturers to market drugs without competition.30 At the expiration of the patent and regulatory exclusivity terms, generic drug manufacturers may enter the marketplace more efficiently and at a lower price by complying with formula and manufacturing specifications already approved by the FDA (or the equivalent national regulatory authority).31 Under U.S. law, generic entrants are also encouraged with less stringent regulatory pathways and the possibility of 180 days of exclusivity if they are the first to the market.32 In 2017, generic drugs constituted around 70% of total prescription drugs dispensed but only made up 16% of total drug spending.33 Despite the development of an extensive regulatory framework, drug pricing still faces considerable scrutiny from Congress.34
There are good reasons that patents and regulatory exclusivities are not the only intellectual property protection deployed as part of firms’ strategies to maximize revenue. When challenged, small molecule drugs especially may fail tests for novelty and non-obviousness essential for patent validity.35 Under U.S. federal law, generic manufacturers are encouraged to challenge the validity of patent claims before the technical expiry of the patent. By filing a so-called “paragraph IV” certification (named after its location in the Code of Federal Regulations), generic applicants, as part of their submissions, submit claims that one or more drug patents are “invalid, unenforceable, or will not be infringed by the manufacture, use, or sale of the drug product for which the [generic] application is submitted.”36 In order to do so, the generic manufacturer must notify the patent holder of the patent challenge.37 The patent holder must then file an infringement suit within 45 days to avoid immediate approval of the generic application.38 If an infringement suit is filed within 45 days, then a 30-month stay is granted by the FDA to allow the parties to resolve the dispute.39 If a generic manufacturer successfully challenges the validity of a patent, then it is granted 180 days of generic market exclusivity upon approval.40 If the patent is found to be invalid, the generic manufacturer still has to wait for the expiration of the exclusivity period granted by the FDA upon approval of the new drug product.41
After this process or expiration of the patent or regulatory exclusivity period, manufacturers rely upon alternative forms of intellectual property protection, some of which have stirred controversy.42 Strategies including “evergreening,” “authorized generics,” “citizen petitions,” and “pay for delay” allow firms to increase the length of market exclusivity and limit competition in ways related to, but technically outside of, the intellectual property sphere.43 “Evergreening” means the patenting of peripheral features of drugs, like their coating or normal metabolites, that allow claims for longer exclusivity even though those patents do not relate to the active pharmaceutical ingredient.44 “Evergreening” allows manufacturers to protect “new” drugs with patents following the expiration of the old patent.45 These follow-on products are initially cheaper, which encourages prescribers to adopt their use, and by leveraging the trademark, trade dress, and brand of the follow-on product, drug manufacturers can maintain a significant share of the market.46
Under “pay for delay” agreements, brand-name pharmaceutical firms offer to pay generic manufacturers to delay the release of a generic drug.47 These receive heavy criticism because they cost U.S. consumers more than $3.5 billion annually due to increased drug costs.48 “Citizen petitions” also delay generic approval because firms may submit these to the FDA for priority review to have the FDA review the generic applications for possible changes. 49 Brand-name manufacturers can also release their own “authorized generics” as patent or exclusivity expiration nears.50 If the “authorized generic” is the first generic on the market, it can obtain 180 days of generic exclusivity.51 Lastly, brand-name manufacturers may limit generic manufacturers’ ability to do bioequivalence testing by refusing or delaying access to the brand-name drug.52
Aside from these strategies, monetary and injunctive relief is available for brand-name manufacturers for claims related to copyright, trademark, trade dress, and trade secrets.53
Copyright protects expressions of ideas, although not the ideas themselves.54 As soon as an idea is expressed in a fixed, tangible medium, copyright protection generally attaches.55 Copyrights can be held by individuals or corporations. For individuals, the copyright lifespan is for the life of the author plus an additional 70 years.56 For firms (technically works for hire), the copyright lifespan is the first of 120 years from creation or 95 years after publication.57
Copyright protection for pharmaceutical manufacturers typically protects the packing material, the design and appearance of the package, and the labeling from being infringed, copied, or duplicated and from unauthorized use.58 However, this does not protect medical literature; it only protects the “unique form of designing or explaining” the manufacturer’s products.59
In the United States, copying a drug label is not generally copyright infringement if the FDA deems it necessary for approval of generic drugs, and if it does not interfere with existing principles of copyright law.60 Because the U.S. Food, Drug, and Cosmetics Act requires compliance with the labeling guidelines to reassure bioequivalence of generic drugs, the FDA may require verbatim compliance with previously approved drug labeling.61 Therefore, labeling may only be protected by copyright if the manufacturer adds creative parts to the labeling or adds labeling beyond the FDA’s requirements.62
In some countries, copyright claims can arise in the pharmaceutical industry regarding product monographs.63 A product monograph is a publicly available document containing information regarding the safety and efficacy of a particular drug.64 In those cases, although the monographs are public scientific data, copyright infringement claims may be asserted if one or more competitors substantially reproduces a manufacturer’s product monograph.65
While copyright may serve a relatively limited function in protecting drug-related information from legitimate competitors, it plays a special role in the context of counterfeit, falsified, and substandard drugs.66 “Unfortunately, there are currently no accurate estimates of the global burden of falsified and substandard drugs precisely because activity occurs in global black and gray markets.”67 Evidence suggests, however, that the problem is most severe in low- and middle-income countries, so copyright plays a particularly important role in the customs context, where authorities examine imports for copyright infringement specifically.68 Imitation drugs mimic other drugs or substances in appearance, whereas counterfeit drugs copy another drug’s label, container, and/or identifying marks.69 In that respect, copyright and trademark share important features with respect to pharmaceutical firms’ intellectual property strategies. As with trademark protection, which will occupy the remainder of this Article, rights holders are often accused of over-enforcing their claims (for example, asserting copyright infringement at the border when the extent to which that protection applies may be in doubt).70 Nevertheless, copyright, patent, and trademark play important roles in a comprehensive intellectual property strategy.71
While patents protect products and copyrights protect the expression of ideas fixed in a tangible medium, trademarks protect “any mark, name, or logo under which trade is conducted for any product or service and by which the manufacturer or the service provider is identified.”72 Trademark protection may also extend to sounds, scents, flavors, textures, and product appearance.73 In the case of pharmaceuticals, other non-traditional marks (such as shape) can be protected as “trade dress” if the appearance of the drug has acquired distinctiveness.74
Within limits, trademark protection provides an incentive for firms to invest in the quality of goods and services and, relatedly, to reduce the costs to consumers of identifying products with desirable quality and price in the same class of products (“search costs”).75 Without laws prohibiting trademark infringement or misappropriation, imitators would be enabled to free ride on those investments and dupe consumers.76 Where the product supplied is not only inferior but hazardous—medicines are an important example—the concern about quality is magnified.77 When well-functioning, trademark protection thus promises a mutual benefit to firms and consumers.78
In the United States, the Lanham Act created a system of federal trademark registration and federal claims of relief for trademark infringement.79 To be registered as a trademark, the mark must be distinctive.80 In the context of trademark registration, the most distinctive marks have “inherent distinctiveness” if they are arbitrary, fanciful, or suggestive.81
Trademarks are one of the most important forms of intellectual property protection available to pharmaceutical firms.82 The pharmaceutical industry invests at least $27 billion annually on marketing brand awareness to U.S. doctors and patients.83 Like other forms of intellectual property protection, trademarks can provide a significant market advantage; however, the basis of that advantage differs. Patents and regulatory exclusivities prevent others from mimicking physical product features.84 In that respect, trademarks appear less protective—other products with similar physical features may still be sold if their appearance is distinguished. But, unlike patent and regulatory exclusivity protection (or even copyright), trademark protection is potentially perpetual when taking a few relatively inexpensive measures.85
More importantly, the drug’s appearance may be, and frequently is, the most important market advantage: when trademarks protect brands with substantial value, the brand itself becomes a product characteristic that consumers value, even cherish, but competitors may not copy.86 Moreover, because of what trademark is designed to achieve—trustworthiness in the view of the consumer—patients may refuse to switch to lower cost alternatives because doing so is costly—what is generally known as “search costs”—in that they must research the alternative’s origin, price, and reputation.87 There is substantial evidence that name brands of previously patent-protected medicines can maintain a premium price over newly available generic versions of the same medicines.88 AstraZeneca’s prescription drugs Prilosec and Nexium are both known in the marketplace as the “Purple Pill.” Pfizer also succeeded in registering the blue diamond shape of its tablets as a trademark for its prescription drugViagra. In short, in a world where information is costly, it is rational for patients to pay more for what they know rather than spend time researching potentially equivalent products.89
Brand names of drugs are protected by trademark, but this does not include the name of the drug itself.90 Prozac, for example, is also called Erocap, Lorien, Lovan, and Zactin outside the United States, although the name of the compound is fluoxetine.91 For a proprietary name to become a registered trademark, it must be reviewed by both the medicine’s regulatory authority (in the United States, the FDA) as well as the trademark review authority (in the United States, the USPTO).92
The standards of review are different and reflect the mandates of those authorities. The FDA is primarily concerned with proposed trademark names that may induce medication error (for example, a name that may be confused when a physician writes the prescription, a pharmacy fills it, or a patient ingests it). Names proposed for trademark protection are reviewed for visual and auditory similarities to other drugs.93 To protect patients from misidentifying medications, drugs must avoid looking and sounding alike.94 As Katherine P. Califa explains:
The FDA considers spelling similarities such as whether two names share identical prefixes, suffixes, or infixes, and whether the names are a similar length. The FDA also considers the overall “shape” of the words. Do both names have similar looking letters in similar positions in the names – including “tall” letters (“l” “t” “f”), “round” letters (“o” “a” “c” “e” “u”), cross-stroke letters (“T” “Z” “F” “J” “I”), or down-stroke letters (“v” “r” “n” “u”)? The FDA will balance these factors, along with an analysis of the phonetic similarities, to determine the overall similarity between two drug names.95
“The FDA views medication errors as preventable and has essentially adopted a zero-risk tolerance policy. [Overall], the FDA rejects proprietary names at a rate of 40% or more . . . .”96
The USPTO, on the other hand, reviews drug names to determine whether the new trademark is capable of registration, whether the new trademark conflicts with a prior trademark application or registration, and whether the trademark application complies with the USPTO’s rules.97 The USPTO’s primary considerations when evaluating whether to grant registration include whether the mark is sufficiently distinctive and whether there is a likelihood of confusion with respect to other registered marks.98 “The ‘likelihood of confusion’ test considers factors such as similarities in marks, the relatedness of goods and services, the relatedness of trade channels, market conditions[,] and the number and nature of similar marks in use for similar goods.”99
Trademark and trade dress protections are used to signal to consumers the source of a product; trademark generally addresses the name, logo, or symbol of a product whereas trade dress addresses the visual appearance of a product or its packaging. The standard for claiming trademark infringement has increased over the years as courts have shifted the burden to the party claiming trademark infringement to prove a “likelihood of irreparable harm” to obtain injunctive relief.100 For many years, trademark infringement claims were granted a “presumption of irreparable harm,” allowing for injunctive relief.101 However, following the Supreme Court’s rulings in eBay v. MercExchange and Winter v. NRDC, the standard changed from a “presumption of irreparable harm” to a burden upon the party claiming a “likelihood of irreparable harm.”102 Under current U.S. law, a plaintiff claiming trademark infringement must satisfy the elements in place for all types of injunctive relief. A plaintiff “must establish that [they are] likely to succeed on the merits, that [they are] likely to suffer irreparable harm in the absence of preliminary relief, that the balance of equities tips in [their] favor, and that an injunction is in the public interest.”103
Within the protections legally offered by trademark, “trade dress” may apply to a product, giving additional claims against competitors.104 Trade dress is generally a more fragile form of intellectual property protection than trademark, but in the context of medicines, it wields enormous influence in the control of entry by competing products.105
To qualify as trade dress an attribute must meet three criteria: it must be nonfunctional, it must lead to confusion (or deception) if imitated, and it must have a secondary association with the product for the consumer. A product’s functional attributes are essential to the use or purpose of the product or must affect the cost or quality of the product.Functionality is key in pharmaceutical-related trade dress, because if a company with a brand-name drug owned exclusive rights over a functional attribute of that drug, a competitor could not offer a truly equivalent generic version.106
Under U.S. law, trade dress is generally divided into two types: product design and product packaging.107 If the identifying dress serves a function, trade dress protection is unavailable.108 Typical functional attributes of drugs are safety and efficacy, although courts have found features like chocolate flavoring or a “pleasing” pink color to serve a functional purpose.109 To claim trade dress infringement, firms endeavor to avoid disclosing or advertising utilitarian advantages of features that may serve as the basis of trade dress protection.110
Section 43(a) of the Lanham Act, which codifies the federal unfair competition act, includes trade dress protection from infringement if the criteria above are satisfied.111 Courts’ interpretations of the criteria for trade dress protection under the Lanham Act are consistent for the first two elements. However, the third element (secondary association) has divided authorities. Some courts require trade dress to have “acquired secondary meaning” while other courts require a showing of either “secondary meaning” or that the product is “inherently distinctive.”112
In the pharmaceutical context, “secondary meaning” suggests that the protected mark leads a patient or consumer to associate that dress or mark with the drug.113 “Secondary meaning” is the traditional rule that results from consumer association of a product with a single source or manufacturer rather than the product generally.114 “Inherent distinctiveness” requires a product to have distinguishing characteristics that are an indication of the source or manufacturer.115 “Secondary meaning” is acquired over time, while “inherent distinctiveness” is immediate.116 To meet the “inherent distinctiveness” standard, a product will likely have to be considered “arbitrary,” “fanciful,” or “suggestive” as a trademark.117
In the pharmaceutical context, manufacturers have asserted trademark rights regarding the shape and color of drug capsules.118 In In re American Home Products Corp., the drug manufacturer attempted to register a “tri-colored three dimension circular shaped design.”119 There, the Patent and Trademark Office determined that the drug met the qualifications for trademark registration.120 The tri-coloration and shape were not considered “inherently distinctive.”121 However, the extensive marketing for more than 20 years that was directed at identifying the drug based on its coloring scheme was “clearly and unambiguously” used to promote trademark recognition and “secondary meaning.”122
Generic manufacturers have generally asserted that brand-name manufacturers may not legitimately assert trade dress protection because the aesthetics of drugs are “functional.”123 A mark is “functional” if a manufacturer’s competitors would need the mark to communicate information about their products to consumers.124 The issue has divided courts interpreting and applying trade dress law.125 Two cases demonstrating differing applications of trade dress law to aesthetic properties of drug products are relevant for the recommendation made in Part III.
In general, the functionality doctrine allows for the protection of color, for example, if the color is not “essential to the use or purpose of the article” and does not “affect the cost or quality of the article.”126 Courts have upheld functionality arguments barring trade dress in some pharmaceutical contexts when patients associate product features with therapeutic care.127 In Ives Lab., Inc. v. Darby Drug Co., Ives sued generic manufacturers for utilizing a similar color scheme for varying doses of cyclandelate, a medicine taken mostly by elderly patients with vascular diseases, which Ives sold under the trademark Cyclospasmol.128 A functionality defense was successful after first being reversed, and then subsequently upheld after multiple appeals.129
Ives manufactured cyclandelate, marketing it as Cyclospasmol in 200mg doses contained in pale blue capsules imprinted with “Ives 4124,” and 400mg doses in red and blue capsules imprinted with “Ives 4148.” The generic manufacturers purchased bulk cyclandelate powder and colored capsules to assemble their products in the same color-coded dosage scheme. The court held that the capsule colors were functional and that “secondary meaning” of the colors as a means of identifying source, rather than chemical ingredient, function, or dose, was not shown.130
The court finds that the colors are functional in several respects. First, many elderly patients associate the appearance of their medication with its therapeutic effect. There was testimony that some patients refuse to take equivalent drugs of a different color despite explanation of the equivalence by their doctors. Other patients eventually accept equivalent drugs of a different appearance if their physician assuresthem that the prescription was filled correctly but are caused considerable anxiety and confusion by the change. When patients associate the drug with its therapeutic effect in this manner, to insist that defendants use a different color would unjustifiably put them at a competitive disadvantage. Thus color is an important ingredient in the commercial success of the product.
Second, some patients co-mingle their drugs in a single container and then rely on the appearance of the drug to follow their doctors’ instructions. One doctor testified that he prepares a chart using the color and shape of the medication to help disoriented and forgetful patients avoid confusion between several drugs. While this practice is not universal, clearly some doctors use the appearance of a drug in communicating with their patients and in assisting them to take the correct medications at the appropriate times.131
Subsequent cases have recognized that “competitors might be free to copy the color of a medical pill where the color serves to identify the kind of medicine . . . .”132 Therefore, under some circumstances, the color and shape of drugs carry utilitarian functions and thus are ineligible for trade dress protection.
However, the extent of the freedom to copy colors for identification purposes may be limited. In Johnson & Johnson v. Actavis Group, the U.S. District Court for the Southern District of New York concluded that even if a yellow-gold color was generally associated with over-the-counter antibiotic ointments, the particular use of that color on packaging of Johnson & Johnson’s Neosporin, an antibiotic ointment, was not essential to its use by consumers and awarded summary judgment against a functionality defense.133
Neosporin is packaged in a tube that Johnson & Johnson (J&J) argued was distinguished by a yellow-gold background, a green color and particular typeface for the brand name, and a curving arrow in the gold/yellow color. Actavis, the generic manufacturer, sold the antibiotic ointment in a tube with the same yellow-gold feature, but none of the other features asserted to have trademark and trade dress protection.134
J&J sued Actavis for violation of its trademark and trade dress. Actavis argued that the yellow-gold color was functional, allowing consumers to identify that the product contained an antibiotic. Actavis provided evidence of consumer association between shades of yellow and antibiotics, and it pointed out that the gold-colored drop on packaging for J&J’s Band-Aids signified the presence of an antibiotic ointment (that itself was manufactured by Actavis for inclusion in J&J’s Band-Aids). However, J&J provided evidence that other antibiotic ointments were sold in other colors of packaging.135
Although the separate issue of “secondary meaning” was held to be a disputed issue of fact, the court granted summary judgment for J&J on the issue of functionality, holding that protecting the color would not significantly hinder competition.136 Thus, while evidence of an association with therapeutic effect that was “not universal” in Ives was sufficient to demonstrate functionality, similar evidence of an association between yellow-gold and antibiotic function was not enough to allow a functionality defense to reach a jury in Johnson & Johnson, demonstrating that the functionality of aesthetic properties of drugs is fact-specific and subject to significant uncertainty.137
To summarize, in litigation, trademark and trade dress protections are handled similarly, with some additional burdens placed upon the latter class of plaintiffs.138 Trademark protections involve a mark placed on the product or its packaging, whereas trade dress protections involve the aesthetic of the product or its packaging.139 Because trade dress is a subset of trademark protection, claims must conform to the same standards as trademark protections.140 However, courts seem uncertain as to whether a “secondary meaning” standard or an “inherent distinctiveness” standard is optimal for determining if a manufacturer should be granted trade dress protections.141 Finally, in the pharmaceutical context specifically, a product’s appearance (like its color or shape) may have functionality (allowing patient identification of therapeutic effect) and be barred from trade dress protection.142 However, significant uncertainty arises due to the fact-intensive inquiry involved in a functionality defense.143
As will be more fully discussed below, in the context of prescription drugs, trade dress protections (or at least the uncertainty and expense of overcoming purported protections) have large impacts on patient health outcomes. Patients are often unable to recognize medications after generic substitution of functionally equivalent (but aesthetically different) medications. The changes reduce patient adherence or the successful continuation of treatment regimens. This causes a negative perception of generic medications because patients associate a loss of safety and efficacy with the change in appearance.144
Whatever the effect of trademark and trade dress protections elsewhere in the economy, their effect on patients deserves special scrutiny. More than131 millionpeople—66% of all adults in the United States—use prescription drugs. Utilization is particularly high for older people and those with chronic conditions.145 Women are generally more likely than men to use prescription drugs; approximately 40% of men and 66% of women age 18 to 34 use prescription drugs, although those populations converge as they reach 80.146
This Part explains why trademark and trade dress law cause medication adherence problems, raise barriers to efforts to lower prescription drug costs, and increase the risk of medication error. Trademark and trade dress law force generic manufacturers to adapt the color, appearance, and shape of the medicines they sell, and there is not uniformity as to how generic firms approach drug appearance—only that they not infringe on the appearance of trademark and trade dress protected features. Because pharmacies switch generic supplier firms with some regularity, this means that patients may receive different looking medications more than once or twice per year. Thus, trademark and trade dress law keep prices high, cause patient confusion, and result in medication error and patient nonadherence.
Patient adherence to prescription drug regimens is essential for maintaining health and avoiding severe illness and premature death. Patients are considered adherent to medications when they take prescribed agents at doses and times recommended by a healthcare provider and agreed to by the patient.147 Patient adherence to prescription drug regimens is affected by many factors of unequal weight, but a substantial body of evidence suggests that, in aggregate, cost and potential confusion are important factors. In a survey of 14,464 Medicare beneficiaries, patients who did not fill at least one prescription reported the following reasons: “thought it would cost too much” (55.5%), “medicine not covered by insurance” (20.2%), “didn’t think medicine was necessary for the condition” (18.0%), and “was afraid of medicine reactions/contraindications” (11.8%).148
The relationship between adherence and cost is more emphasized among the socioeconomically marginalized, including racial and ethnic minorities. Specific factors that have been identified as barriers to medication adherence among inner-city patients with low socioeconomic status include high medication costs, lack of transportation, poor understanding of medication instructions, and long wait times at the pharmacy.149 “Patient nonadherence to prescribed medications is associated with poor therapeutic outcomes, progression of disease, and an estimated burden of billions per year in avoidable direct health care costs.”150
Over 90% of prescription drugs dispensed are generic drugs, both because they are less expensive and because state mandatory substitution laws require that pharmacies in most states fill prescriptions with generic versions where available. 151 For approval by the FDA, generic drugs must be the bioequivalent of the brand-name version, meaning it must have the same “dosage form, safety, strength, route of administration, quality, performance characteristics and intended use.”152 Unlike drug names, the FDA does not regulate the physical appearance of drugs, although it has issued guidance with respect to size and shape of tablets and capsules as well as some aspects of packaging. 153 Because of this, pharmaceutical companies may protect the physical attributes of their drugs through trademark and trade dress.154
The essential question with respect to trademark and trade dress protection in the pharmaceutical context, then, is: does the benefit to patients from identification of brand-name prescription medications (the trademark rationale) outweigh the cost to patients in the form of reduced adherence attributable to more expensive medicines and the cost imposed when trade dress confuses rather than clarifies (the “IP cost” and the “confusion cost”)? This Article argues that the answer is “no” and makes specific recommendations to incorporate that answer into law.
Physicians and public authorities (who often pay for treatment for some or all of their populations) have emphasized supply-side measures to ensure access to medicines at an affordable cost—to individuals when they are required to pay and by the public treasury for populations covered by universal health insurance systems. 155 Supply-side measures include investment in generic manufacturing capability; regulatory and intellectual property incentives for generic manufacturers to enter markets; and state substitution laws that allow or require that pharmacies fill prescriptions with lower cost generic drugs that are therapeutically equivalent.156 For example, streamlining the generic drug approval process in the United States by prioritizing applications from manufacturers who introduce a generic drug with limited competition would decrease prices and similarly limit the number of competing products with disparate visual schemes.157 Supply- and demand-side policies help to encourage the use of generic drugs over brand-name drugs.158
Demand-side policies are necessary to improve prescribing physicians’ and patients’ perceptions of generic drugs to encourage more prescriptions.159 Demand-side policy proposals include charging fees to increase resources for more efficient reviewal processes; addressing anticompetitive strategies; and providing financial incentives to physicians and pharmacists.160 Some European countries have implemented financial incentives to physicians and pharmacists to encourage the use of generic drugs, and similar measures could be taken by states with respect to disease categories where patient confusion is widespread or severe.161 State substitution laws already use the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book) as the measure for substitutability, so at the very least, it would be possible to incorporate a notice system for pharmacies to use when substituting therapeutically equivalent drugs.162
Generic drugs are relatively inexpensive when compared to brand-name drugs because of the less strict regulatory pathway to obtaining approval and the already-existing competitive market for the drug.163 To maintain competitive and sustainable pricing, drug manufacturers must be ensured that a high volume of generic drugs will enter the market and be used through supply- and demand-side policies.164 Regulations have generally addressed supply-side policies and decreased the average cost of generic drugs by 10-80% of the cost of brand-name drugs while improving access to the market.165 However, demand-side policies are needed to incentivize prescriptions of generic medications by physicians and substitutions to generic drugs by pharmacists, and to improve patients’ perceptions of the safety and efficacy of generic drugs.166
Demand-side measures should include laws, regulations, and judicial interpretations that acknowledge the special costs that trademark and trade dress impose in the prescription drug context.167 Although sometimes it may be necessary to prescribe brand-name medications (for example, if a patient has an allergy to the generic alternative), the majority of the time, generic drugs are avoided due to misconceptions or habits by physicians.168 Several successful policies exist addressing generic drug misconceptions in European countries and the United States.169 Studies have shown that low health literacy action plans can also encourage adherence to generic drugs because the physician and/or pharmacist will be more involved with counseling patients regarding therapy, which may include discussing the visual differences between brand and generic forms of the prescription drug.170
As analyzed above, trade dress allows pharmaceutical firms to apply identifiable physical attributes to their products if they do not change the functional attributes of the medications—indeed, functionality would render those features ineligible for trade dress protection.171 Health scholars have long criticized the protections given to medications under trade dress doctrine for at least two reasons. As a purely legal matter, patient adherence can be shown to depend upon drug appearance, rendering all aspects of drug appearance “functional.”172 For example, patients who take multiple medications are often 80 years of age or older with higher rates of visual or other impairment, increasing the risk of errors.173 As a result, the legal framework introduces deadweight loss by incentivizing pharmaceutical firms to make design decisions for the purpose of preserving monopoly power rather than patient benefit.
Studies have shown an increase in patient harm because of nonadherence due to reliance on the physical appearance of drugs.174 Patients receiving generic versions of the same medication receive pills of different sizes, shapes, and colors routinely because of trade dress protections.175 In a study testing medication nonadherence for those with uncontrolled blood pressure, the ability of a patient to identify their medication based on its appearance was directly correlated to a diagnosis of uncontrolled blood pressure and an increase in hospital visits over the course of a year.176 Patients who relied solely on the appearance of medication were 1.26 times more likely to report uncontrolled hypertension and 1.35 times more likely to report hospitalization in the past year.177 These patients self-reported an increased nonadherence to generic medications.178
Similar outcomes have been reported in other studies. For example, in a study of 11,472 patients who had failed to fill a prescription for anti-epileptic drugs (in 4 shapes and 37 colors) within 5 days of the elapsed days were approximately 30% more likely to have had the color of their pill changed before that failure relative to a control group of 50,050 patients who did not so fail.179 Gaps in filling medication were 27% greater following a color discordance in anti-epileptic drugs when compared to a control.180> For patients suffering from a seizure disorder, there was a 53% increase in prescription filling gaps when a color discordance occurred prior to filling.181 Color appeared to be more relevant than shape.182 Likewise, with prescription drugs dispensed to patients following myocardial infarctions, a 30% increase in nonadherence was observed in patients who received a medication with a different shape or color.183
An international study tested members of the United States, China, and Colombia to determine the psychological effects of different colors and shapes of medication.184 The study revealed that patients associate certain characteristics with different shapes and colors.185 For example, a pink-colored drug may be viewed as sweet compared to a white-colored drug that may be perceived as salty, or a round-shaped drug may be perceived as more easily swallowed compared to a drug with edges.186 This study suggests that people around the world may have similar perceptions regarding the physical appearance of drugs, and that these perceptions may have adverse effects on a patient’s adherence to a treatment plan.187
The evidence linking objective measures of prescription drug appearance is even more important given that health literacy plays such an influential role in a patient’s independent ability to adhere to prescription drug regimens.188 Health literacy is correlated to nonadherence to medication or to nonadherence to a dependent’s treatment plan with medication.189 In the aforementioned study for uncontrolled blood pressure, patients who were unable to identify their medication by name or appearance were more likely to miss taking a medication compared to those who could identify all of their medications by name or appearance.190 However, this difference was not significant when compared to those who relied solely on identifying medication based on its physical appearance.191
Moreover, there is some evidence that the need to closely align prescription drug appearance with adherence will disproportionately affect children. “Low health literacy . . . is likely to contribute to poor management of child asthma.”192 Physicians who have utilized low literacy written asthma action plans (WAAP) with parents or guardians have seen greater medication adherence by child patients.193 The low-literacy WAAP involved clear communication that included a presentation of medication instructions and inhaler colors, spacer use, a statement including the need for everyday use and the importance of the “yellow zone” on Flovent and Singulair, and explicit words used to present symptoms of exacerbation.194 The low-literacy WAAP showed self-reported increased adherence to treatment and an increased understanding of the medication, as well as an increased satisfaction amongst the physicians utilizing the plan.195
Thus, substituting generics with differing look-and-feel subject to trade dress protections implicates poorer health outcomes. Nonadherence to medication is shown to be related to a patient’s ability to identify the medication based on the color of the pill and health literacy. 196 Due to the number of generic medications on the market and the prevalence of generic substitutions by physicians and pharmacists, patients are exposed to medications of bioequivalence that differ in physical appearance.197 The difference in appearance casts doubt on a patient’s perception of efficacy, which contributes to nonadherence and potential adverse outcomes.198
These studies suggest that modifying the current FDA regulations to prohibit or limit drug manufacturers from claiming trade dress protection on the appearance of drugs could lead to more consistent adherence to drug therapies by improving patient confidence in the safety and efficacy of prescription drugs.
Regulatory authorities, including the FDA, have long known that aspects of prescription drugs (including pill shape and packaging) potentially impact rates of medication error, defined as “any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of the healthcare professional, patient, or consumer.”199 In guidance released in 2013, the FDA acknowledged that packaging trade dress could make it difficult for healthcare professionals, caregivers, and/or patients to readily locate and understand critical safety information.200 The guidance encouraged pharmaceutical firms to avoid or minimize the use of corporate trade dress that could make it difficult for end users to distinguish between different medications or different strengths of the same medication.201
For example, the FDA recommends that the container label size should not be too small and should feature text sizes that are easy to read. The Guidance goes so far as to almost dictate a 12-point sans serif font size (such as Arial) to improve readability of pharmaceutical labels. In addition, the FDA seeks to define an acceptable color contrast between the text and the container label background color to afford adequate legibility of the text. Most importantly, the FDA intends to actively discourage the use of logos, bars, stripes, watermark graphics, lines, and symbols on container labels and / or carton labeling because they can distract the reader from important information and add to label clutter. Instead, the Guidance recommends placement of images of tablets and / or capsules on the packaging so patients or caregivers can verify the contents of the container and supposedly reduce medication errors.202
Similarly, in 2015, the FDA released guidance on the size, shape, and other physical attributes of tablets and capsules, acknowledging that “differences in physical characteristics (e.g., size and shape of the tablet or capsule) may affect patient compliance and acceptability of medication regimens or could lead to medication errors.”203 In both its 2013 and 2015 guidance, the FDA was explicit that the findings were non-binding and have had a correspondingly minimal effect on firm behavior. 204 In other words, the FDA has expressed clear awareness that the size, shape, and color of medications matter (or are arguably “functional”) for purposes of patient understanding and avoidance of medication error. That awareness should serve as a basis for judicial interpretations of the law when adjudicating trademark and trade dress claims in the prescription drug context.
This Part addresses legislative, regulatory, and judicial measures that may be taken with respect to trademark and trade dress barriers to producing generic medicines that appear as original drugs, cause less patient confusion, result in less medication error, and allow generics to occupy a larger share of the market, thereby lowering costs. While legislative solutions are always more burdensome, some of the measures below may require changes in the federal Food, Drug & Cosmetics Act. But others may be implemented through existing FDA authorities and the adoption by federal courts of reasoning applied in the Third Circuit’s Shire decision.
The legislative and regulatory solutions to many of the problems outlined above are available through existing FDA findings and guidance, statutory text, and judicial opinions that address the reach and limits of trademark and trade dress. Legislatively, Jeremy Greene and Aaron Kesselheim have argued that the FDA could address problems caused by trademark and trade dress by using their existing authority over drug names and applying it to other aspects of drug appearance:
A first step toward reform would be to include FDA certification of pharmaceutical size, shape, and color in the drug-approval process. For example, a pill’s attributes could be proposed by the manufacturer during the original New Drug Application. Currently, such a process occurs for the brand name of the medication; extending it to pill appearance should not require additional legislation. This would create a clear path for generic manufacturers to declare during the ANDA process that their products have similar appearances. Where these drugs do differ (e.g., as in dyes, fillers, or excipients), physicians or pharmacists could still locate manufacturer data from unique identifier codes embossed on pills. Further public health benefits could emerge if the reduction in trade dress helps to combat the physician’s persistent use of, and the patient’s preference for, costly brands when generic equivalents are available.205
For products already on the market, legislation could address the highest priority drug classes where confusion results in nonadherence and impose a color-based scheme, as has already been piloted for inhalers and ophthalmologic products in the United Kingdom and the United States respectively.206
Judicially, reform is even more straightforward. There is already federal appellate precedent for acknowledging that the color, size, and shape of drugs affect adherence. 207 Indeed, in Ives, analyzed above, the U.S. Supreme Court granted review of the case and, while reaching its conclusion on a different basis, acknowledged that the generic producer had offered a legitimate basis for its imitation of pill appearance.208 Acknowledging that these aspects of drugs are functional and clarifying the evidentiary burden to reduce uncertainty would disqualify them from trademark and trade dress protection while not obviously rendering them susceptible of other intellectual property protections like patents that would cause higher prices.
These proposals, of course, address only a specific aspect of the nonadherence problem. Legislation at the state and federal levels could do more to address health illiteracy, which has generally accompanied studies of prescription drugs’ visual effect.209 Greater communication from healthcare providers to patients using health literacy action plans has shown to improve nonadherence to generic medications. Demand-side policies should be enacted by governments to improve physicians’ and patients’ perceptions of generic drugs, including discussing the color schemes and appearance of alternatives.
Trademark and trade dress impose more costs on patients than the benefit they impart through their purported function of helping patients distinguish different kinds of drugs. This Article has analyzed how current use of trademark and trade dress fuel patient nonadherence to prescription drug regimens, cause medication error, and raises prices. Partial and even complete solutions to some of these problems may be found in existing legal authorities. The FDA has already explicitly acknowledged the confusion that may arise through drug names otherwise protected by trademark and has aggressively used its authority to reject 40% or more of names that may result in nonadherence, patient confusion, and medication errors by both providers and patients. It has further implicitly acknowledged in guidance related problems that pill shape, color, and size may raise with respect to the same patients.
What is more, it appears that the new generation of blockbuster drugs—biologic drugs that treat numerous autoimmune conditions—may be similarly affected by trademark and trade dress. As Michael S. Sinha has carefully analyzed, companies are pairing these injectable and inhalable medicines with devices and delivery systems over which they are also patenting functional and non-functional features.210 If the law is not clarified, then these next generation drugs may be just as costly as the last generation of small molecule drugs.
To address these problems, the FDA may expand the reach of its authority with respect to manufacturing to certify pharmaceutical size, shape, and color. Federal judges, who almost exclusively review the issues raised by allegedly trademark infringing drugs, could apply persuasive appellate and U.S. Supreme Court authority to find that most features of drugs are functional.
These measures, of course, are limited to the effects of trademark and trade dress protection on patients. In this context, as in many others, there is a great need for publicly supported programs that expand health literacy, especially in contexts for which there is already a great deal of evidence as to sources of confusion and nonadherence. But the role of trademark and trade dress protection is relatively straightforward and should be addressed in ways more consistent with better individual and public health outcomes.

Tweaking something old and calling it new, on the other hand, is considerably easier. In the pharmaceutical trade, when brand-name companies patent ‘new inventions’ that are really just slight modifications of old drugs, it’s called ‘evergreening.’ And it’s a practice that, according to some who have looked into it, isn’t doing a whole lot to improve people’s health. ‘Typically, when you evergreen something, you are not looking at any significant therapeutic advantage. You are looking at a company’s economic advantage,’ says Dr. Joel Lexchin, a professor in the School of Health Policy and Management at York University in Toronto, Ontario. ‘The response from the brand side is that they are trying to protect their markets so they can further invest in R&D [research and development]. And even if they make a modification to a drug, doctors are still quite able to prescribe the generic version of the older product. Having said that, the brand-name companies put an awful lot of money into marketing the newer version, and that marketing is designed to affect what doctors do.’”).
- Id. In one example, in Switzerland, a co-payment incentive program combined with an increase in generic drug competition contributed to the replacement of brand-name drugs and the reduced prices of brand-name drugs. However, this loss of profit from brand-name drugs was fully offset by successful marketing of follow-on drugs through evergreening strategies.

In order to be copyrightable, a work must be original, at least minimally creative, and fixed in a tangible medium of expression. Original, in this sense, means that the work was not copied from another source. It is a binary distinction. Creativity is a scalar concept involving more or less novelty or cleverness. The Court has explained, however, that the threshold for creativity in copyright law is very low. And to constitute a fixed writing, a work must be made ‘sufficiently permanent or stable to permit it to be perceived, reproduced, or otherwise communicated for a period of more than transitory duration.’”).

In this vein, courts have typically asserted, first, that trade dress can act like a traditional trademark, helping consumers identify and distinguish products,and second, that so long as the functionality doctrine excludes protection for those features that represent ‘the best or one of a few superior designs available,’trade dress protection will generate no anticompetitive consequences. However, this analysis fails to justify recognition of trade dress as principal register subject matter for two reasons. First, the Court has repeatedly warned against ‘simplistically . . . assuming that whatever furthers the statute’s primary objective must be the law.’Second, the policy analysis that courts have offered both overstates the benefits that such recognition achieves and understates its true cost. A more careful analysis of the policies implicated by trademark protection fully justifies distinguishing between the protection of words and symbols as trademarks and the protection of trade dress under principles of unfair competition.”) (footnotes omitted).

The argument that, like functional elements, color ought to be automatically denied protection because of the risk of creating monopolies through tying up all available colors does not seem persuasive; the evidence showed that, in addition to the other primary colors, an endless number of color combinations was available to the defendants. The case for functionality thus depends on the evidence proffered by defendants that copying whatever colors Ives had chosen served a number of utilitarian purposes,essential to effective competition. At this stage of the case we need not go beyond saying that the judge was warranted in considering this to be fairly arguable. With respect to secondary meaning we cannot say that Ives would necessarily be unable to establish that consumers had come to associate the blue and blue-and-red colors with the trademark Cyclospasmol.”) (citations omitted); Daly & Emery, supra note 10.

These numbers in France increased following the implementation of a reference price scheme covering off-patent drugs in 2003.”) (citations omitted).

The FDA’s guidance is not binding, and by its own terms, it applies only to new generic drug products submitted to the Office of Generic Drugs via an abbreviated new drug application (ANDA) . . . . [G]eneric drug companies should be careful that their efforts to adhere to FDA guidance do not expose them to trade dress infringement claims.”).
