The COVID pandemic has underscored that intellectual property (IP) can limit the ability to address public health crises because IP owners have the legal right to bar others from making needed supplies. However, what is less well understood yet critical to making medical treatments available are IP-related barriers existing in regulatory laws that complement traditional IP protection. In other words, even if a potential manufacturer of a needed treatment can obviate patent and trade secret hurdles, that manufacturer could be thwarted due to less well understood regulatory barriers.
There are two key barriers to treatments for which regulatory authorities are involved in review, such as drugs and vaccines. The most dominant is “data exclusivity,” which can prevent approval of follow-on treatments (a generic or biosimilar)Footnote 1 by barring reliance on previously submitted clinical data of the comparator original that is used to expedite regulatory approval of these lower-cost treatments.Footnote 2 In addition, in some countries “patent linkage” can bar regulatory approval of a safe and effective drug solely due to alleged infringement of patent(s) associated with making that drug.
The chapter begins with the genesis of these regulatory protections and their general parameters before discussing their prevalence among countries. It then turns to discussion of proposed and actual modification of Trade Related Agreement on Intellectual Property Rights (TRIPS) requirements for COVID and how that intersects with these regulatory barriers. The chapter concludes with recommendations.
1 Background
A Genesis
Data exclusivity and patent linkage were both introduced in the United States in 1984 as part of a legislative compromise intended to promote development of new drugs and expedite generic entry, along with other amendments to patent laws to similarly promote the same balance.Footnote 3 Although some aspects of these laws create regulatory barriers, they have also helped to promote more generics.Footnote 4
The new law promoted generic entry by permitting proposed manufacturers of generics to rely on clinical data of the originator drug companies to help infer the generic is safe and effective with a limited showing of bioequivalence to the original; this essentially provided an expedited approval process that avoided unnecessarily duplicating all the same clinical tests of the original approved drugs.Footnote 5 This reliance was only possible after a newly established term of data exclusivity from the date of approval of the originator. Permitting subsequent companies to rely on this clinical data to obtain regulatory approval was a major improvement. Previously, the Food and Drug Administration (FDA) considered this data to be an indefinite trade secret.Footnote 6 As a result, there were few generic drugs approved even after patents on the original drugs expired since potential generic companies needed to create their own clinical data, but could not recoup costs to do so.Footnote 7 Whereas the manufacturer of a new drug can easily recoup the costs of its clinical data by charging a premium enabled by a patent, a generic is by definition a copy of another’s drug and so would not meet the patent requirement of being “new.” To address pioneer companies’ concerns about the ability of generic companies to “free ride” on the time and expense of their data, data exclusivity was created.
In addition, generic companies obtained an exception from patent infringement for making a patented drug as part of clinical tests needed to create its proposed equivalent to conduct bioequivalence testing and obtain regulatory approval. This patent exception promoted generic approval and avoided undue extension of the patent term that would otherwise occur, since it typically takes years for regulatory authorities to review data. Although new at the time, most countries today have similar laws and the patent exception is also consistent with international IP rules.Footnote 8
Creators of new drugs also obtained benefits from this new law. First, they obtained an extension of the patent term to compensate for the fact that review of drug applications usually reduces the effective term of a patent since a patented drug has no market power without regulatory approval.Footnote 9 Moreover, these creators obtained patent linkage, a powerful new way to bar competitors from the marketplace by delaying regulatory approval to address alleged patent infringement. As a result of this law, applicants of new drugs submit a list of patents that would allegedly be infringed by manufacturing the drug when seeking regulatory approval. When drugs are approved, the patents covering the drugs, as well as their expiration dates, are published in conjunction with the drugs so that potential generic applicants are aware of these patents.Footnote 10 Generic applicants need to certify as part of their regulatory approval that there are no unexpired patents, thus creating a link between patent status and regulatory approval.Footnote 11 Although the United States created a mechanism for a generic to potentially challenge whether linked patent(s) were invalid or not infringed, the system still generally resulted in an undue delay of two or more years while the patent issues were litigated.Footnote 12
In 1987, the EU created a similar abbreviated pathway for approving generics by permitting them to rely on earlier clinical data after a newly created period of data exclusivity expired.Footnote 13 Data exclusivity was granted for different reasons in the European Union than in the United States. Not all EU member states at the time provided the scope of patent protection desired by the pharmaceutical industry; Spain and Portugal did not provide product patents to pharmaceuticals and instead only patented methods of making drugs.Footnote 14 The European Union, however, has thus far not adopted patent linkage; the EU considers patents irrelevant to the function of a regulatory agency that is intended to protect public health.Footnote 15
B Parameters of Regulatory Barriers
Data Exclusivity
Data exclusivity essentially bars a subsequent applicant from relying on the clinical data of the original manufacturer for the period of the exclusivity to seek expedited approval of new treatment without creating its own clinical data.Footnote 16 During the term of data exclusivity, no reliance is possible and applications for follow-on versions will not be approved.Footnote 17 Some countries extend the term of exclusivity based on submission of additional clinical data relating to new use of an existing drug, or pediatric use.Footnote 18 Also, some countries provide a separate type of exclusivity to promote “orphan drugs” to treat rare conditions even if there is no reliance on any clinical data.Footnote 19
Data Exclusivity Rationale?
Proponents of data exclusivity argue that it protects and encourages investment in producing clinical data that supports new drugs.Footnote 20 However, this is the same justification for the existence of patent protection, such that some have argued there is no need for both data exclusivity and patent protection.Footnote 21 That said, the industry and some commentators argue that data exclusivity may be helpful for providing protection for drugs that have some value, even if unpatentable.Footnote 22 In addition, the industry has claimed that data exclusivity will promote more investment in countries that provide it.Footnote 23
But is data exclusivity justified? A new drug must provide clinical data of safety and efficacy to be marketed and the clinical data from these tests are not improved in any way if data exclusivity is granted to its creator. Moreover, the policy reason for providing data exclusivity in countries with less economic means seems particularly tenuous given that it slows access to lower cost drugs without any public benefit. This is especially true since the current data does not show any positive effect of adding data exclusivity on the economic development for countries in the Global South, rebutting the claim that data exclusivity will promote more investment in countries that provide it.Footnote 24
How Data Exclusivity Is Different than Patent Protection
Patents and data exclusivity have different requirements. A patent is only awarded to an invention after verification that it meets certain requirements (such as being novel and having an “inventive step”) and provides a disclosure of information to the public who can then build on this invention; these requirements are considered part of the social bargain to justify the high prices that result from patent protection. In contrast, there are no similar requirements of novelty of a drug, or public disclosure to receive data exclusivity. Rather, it is generally automatically “granted” for a drug deemed to satisfy usual regulatory standards of being safe and effective. Although, like patents, data exclusivity can provide a measure of exclusivity in the marketplace, it cannot be challenged in the same way as patents; for example, whereas patents can be challenged for failing to meet patentability requirements (such as not actually being novel), there is generally no possible challenge to data exclusivity for a drug deemed safe and effective. In addition, unlike the issuance of a patent that comes with an official document that provides its owner legal rights to enforce in a judicial system, data exclusivity is enforced not by its owner, but by government agencies. Essentially, where it exists, governments are barred from approving a subsequent drug that relies on the previously submitted clinical data during the period of data exclusivity.Footnote 25 Unlike with patent protection, nothing is disclosed to the public in exchange for this exclusivity. Whereas patent protection is often justified in part due to the disclosure of how to make and use the invention that might otherwise be kept as a trade secret, there is no similar justification for data exclusivity.Footnote 26 And, in fact, even in countries that do not provide data exclusivity, companies must provide the same clinical data to be able to sell their drug. Also, whereas patents and most other types of IP are enforced by the IP owner, data exclusivity is enforced by regulatory agencies. Lastly, although most countries have an exception from usual patent rights for compulsory licenses, most nations do not have an exception from data exclusivity to ensure effective use of a compulsory license.Footnote 27
Intersection of Data Exclusivity and Patent Protection
When a drug is subject to both data exclusivity and patent protection, the term of data exclusivity may impact whether it lasts beyond patent protection. The effective term of a patent is about twelve years from grant of regulatory approval, which is longer than the five-year term of data exclusivity in most countries.Footnote 28 However, data exclusivity can last beyond the patent term for a drug whose patent application was pending a long time, if a regulatory approval process was lengthy, or if a country provides a longer term of data exclusivity or delay before approval of a generic. Also, in the United States, although there is a five-year term of data exclusivity for conventional drugs, there is a twelve-year term for more complex and expensive biological drugs such as insulin. So, in such cases, data exclusivity can sometimes outlast patent protection, but even then, it could depend on whether there are multiple patents. The arthritis drug Humira, for example, was first approved for sale in the United States in 2002 and although the initial patent on the drug composition expired in 2016, due to a thicket of over 100 patents on different aspects of the drug it is still under some patent protection more than twenty years later despite a novel challenge on antitrust grounds.Footnote 29 There are also situations beyond the United States where generic drugs can be delayed after the patent expires due to data exclusivity or other protection, such as supplementary protection certificates that essentially extend patent protection. For example, a study of these TRIPS-plus provisions imposed on Ukraine found that the average delay of generics was over one year due to such provisions.Footnote 30
In addition, whereas the novelty requirement of patents requires companies to apply promptly (to avoid a bar to patentability), there is no similar criteria that would prompt a company to seek regulatory approval in less profitable countries where data exclusivity applies. Since most countries provide exclusivity from the date of domestic approval, rather than first global approval, there is often no incentive to seek timely approval in all countries – unless a country specifically requires data exclusivity to begin from first global approval. Unless data exclusivity is triggered by first global approval, companies may deliberately introduce products later in less profitable developing countries so that they can first benefit from exclusivity in the wealthier countries, followed by an additional term in the developing country.
Moreover, although patent and data exclusivity are separate barriers, sometimes data exclusivity alone will be a problem. There are different reasons this could be the case. First, there may be no patent either because a patent application was denied, or an issued patent was invalid. So, sometimes data exclusivity alone can be a barrier to generic drugs. This was the case in Russia where the primary patent on a Hepatitis C treatment was partially revoked, but data exclusivity barred generics for six years.Footnote 31
Intersection of Data Exclusivity and Emergency Approval
Data exclusivity, along with the ability to use an expedited path for follow-on approval begins with traditional regulatory approval of a drug. Data exclusivity may not exist when there is emergency approval of a new treatment that is likely to occur during a pandemic based on a more limited showing of data.Footnote 32 For example, in the United States data exclusivity is reflected in laws that bar a subsequent applicant from relying on data from a fully approved drug; there is no expedited generic approval based on emergency approval.Footnote 33 However, depending on how long an emergency situation lasts, there could be time to obtain full approval of drugs initially approved based on emergency authorization. For example, both the Pfizer and Moderna COVID-19 vaccines received full approval in the United States about eight months after emergency approval.Footnote 34
It is also possible that a drug approved before a pandemic could be discovered to be useful for a pandemic. In such a situation, even if there was emergency approval of the drug for the new use, a data exclusivity period based on the original approval could bar a company from obtaining regulatory approval to make a follow-on drug. This seems especially true in a country that has a longer period of data exclusivity. On the other hand, if a drug is long known, data exclusivity would have expired. That was true for hydroxychloroquine, which was initially considered a promising treatment for COVID-19; it was first approved to treat malaria in 1950, such that no data exclusivity existed during the COVID-19 pandemic that would have barred generics.Footnote 35
Patent Linkage
The term patent linkage refers to a conditional relationship between approval of a follow-on drug and the patent status of the original product. If one or more patents are linked to making the follow-on drug, that may delay its marketing approval. Importantly, a follow-on drug could be denied regulatory approval not based on the usual regulatory standards of safety and efficacy, but solely on a potential patent problem. Typically, information about whether a drug (or its active ingredient) would be infringed when made is based on assertions by self-interested patent owners. A company that seeks marketing approval for a new drug typically informs a regulatory agency of patent(s) the company asserts would be violated by anyone making that drug. There is often no independent assessment by the regulatory agency that enforces patent linkage of whether the patent(s) associated with a drug are relevant, let alone valid.Footnote 36
Is There More than One Type of Patent Linkage?
There are different ways that nations provide patent linkage. A country may bar or stay regulatory approval of a generic entirely based on alleged patent infringement.Footnote 37 Another possibility is that a country may permit the patent owner to address the patent issue with the alleged infringer in a litigation or administrative proceeding. Yet another possibility is that a country could notify the patent owner of a follow-on application, but without the need to delay approval to resolve a patent issue. In addition to these three mechanisms, nations may provide the same system of patent linkage for all follow-on drugs, or different systems for generics versus biosimilars.Footnote 38
What Is the Justification for Patent Linkage?
Companies that develop new drugs generally argue that patent linkage is needed to ensure effective patent enforcement.Footnote 39 However, the usual way to enforce patents is for patent owners to pursue their own claims in court. The industry argues that judicial enforcement, even with the possibility of preliminary injunction, is uncertain. It is true that patent linkage can provide more certainty by absolutely barring approval of an allegedly infringing drug. However, it is a costly one for society in terms of preventing timely approval of lower-cost drugs that may not in fact infringe any patents since patent linkage occurs generally without review of patent issues.Footnote 40
What Does Patent Linkage Add to Traditional Patent Protection?
Patent linkage can be a major hurdle that delays entry of follow-on drugs if a regulatory agency stays approval. This is true even in countries that permit the follow-on manufacturer to challenge the patent because such challenges take time, which could be a serious problem during a pandemic. However, patent linkage does not add much to patent protection if a country only notifies the patent owner, rather than delaying regulatory approval.
C International Requirements and Prevalence of Regulatory Barriers
Before discussing the prevalence of regulatory protections globally, it is important to consider whether any international agreements require them. The foundational international agreement concerning IP is TRIPS, which applies to all members of the World Trade Organization (WTO) – that is, most countries of the world.Footnote 41 Since TRIPS was concluded in 1994, the United States and European Union have continued to seek stronger IP protection in a series of free trade agreements (FTAs) often referred to as “TRIPS-plus” agreements since they require more than TRIPS. Data exclusivity is more often required since only the United States requests patent linkage.
Is Data Exclusivity Required?
Whether TRIPS requires data exclusivity has been a major point of contention. The TRIPS provision at issue is part of the provisions related to countries generally requiring trade secret protection. In particular, the relevant part ambiguously states:
Members, when requiring, as a condition of approving the marketing of pharmaceutical or of agricultural chemical products which utilize new chemical entities, the submission of undisclosed test or other data, the origination of which involves a considerable effort, shall protect such data against unfair commercial use.Footnote 42
For countries that require submission of clinical data to approve a drug, which is true in most industrialized countries,Footnote 43 the United States, European Union, and the pharmaceutical industry claim this provision requires data exclusivity, arguing that reliance on the data of another is “unfair commercial use,” but this point is heavily contested.Footnote 44 Although the United States did bring a request for consultation, there has never been a WTO panel decision on this issue, leaving it unresolved.Footnote 45 There was an earlier draft that explicitly required data exclusivity, but it was not enacted, such that a proper interpretation should indicate that data exclusivity is not required, as many scholars and policymakers agree.Footnote 46
Although TRIPS should not require it, this provision may have prompted some countries to adopt data exclusivity. For example, Jordan, Switzerland, and New Zealand adopted data exclusivity when amending their laws to comply with TRIPS.Footnote 47 Even for countries that did not adopt data exclusivity to comply with TRIPS, they may have been required to adopt it because of FTAs that explicitly mandate such an obligation.
Is Patent Linkage Required?
Unlike data exclusivity, most countries do not consider patent linkage to be part of TRIPS.Footnote 48 There is nothing in TRIPS that specifically refers to regulatory authorities and patents. The industry has asserted that the general TRIPS provision about providing expeditious remedies to prevent infringement is violated by a country that does not have patent linkage.Footnote 49 However, patent linkage does not require a method to challenge a patent; that is simply a feature of some types of patent linkage. Moreover, even FTAs that require patent linkage do not necessarily require a method of challenging a patent covering a drug.Footnote 50
Prevalence of Data Exclusivity
There are roughly fifty countries and the EU that provide data exclusivity, which is a substantial number, and yet this represents less than half of the over 100 members of the WTO.Footnote 51 Data exclusivity exists not only in the United States and European Union, where it originated, but also in other high-income countries such as Australia, Canada, South Korea, New Zealand, and Switzerland.Footnote 52 FTAs also require this for lower-income countries such as Bahrain, Brunei, Chile, Colombia, Costa Rica, Dominican Republic, El Salvador, Guatemala, Honduras, Laos, Malaysia, Mexico, Morocco, Nicaragua, Oman, Peru, Panama, Singapore, and Vietnam.Footnote 53 China proposed data exclusivity in May 2022.Footnote 54
The term of data exclusivity is typically at least five years from approval of the original drug in the country granting such exclusivity.Footnote 55 The EU originally required at least six years and permitted variation among member states, but later adopted a uniform eight-year period of exclusivity, largely reflecting industry demands.Footnote 56 The United States has a twelve-year term of data exclusivity for follow-on biologics (complex drugs that are injected or infused such as vaccines), but only a five-year term for generics.Footnote 57 The United States has tried to mandate longer terms for biologics in FTAs, mirroring its domestic laws, but thus far have been unsuccessful.Footnote 58 Other countries often provide the same term for all treatments.Footnote 59
Some FTAs that mandate data exclusivity have mediating factors. For example, some FTAs permit an exception to such exclusivity in the event of compulsory license or public health needs, which Malaysia, Chile, and Columbia have implemented.Footnote 60 In addition, some FTAs mandate data exclusivity but permit countries to specify that the data exclusivity may not exceed the term of patent protection,Footnote 61 or begin the term of data exclusivity not from the earlier date of approval in a partner country, so long as the originator drug is approved shortly after the approval in a partner country.Footnote 62
Prevalence of Patent Linkage
The United States originally negotiated patent linkage in FTAs with high-income countries such as Canada (1993), Singapore (2004), Australia (2005), and South Korea (2007).Footnote 63 The United States proposed patent linkage when negotiating the Trans-Pacific Partnership Agreement.Footnote 64 Although the United States withdrew from that agreement, the patent linkage provision remains in the renamed and now concluded Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), which includes Vietnam, Malaysia, Chile, and Peru.Footnote 65 Japan is also required to provide patent linkage pursuant to the CPTPP, but its official position is that no changes in the law are requiredFootnote 66 since Japan has unofficially considered whether a generic might conflict with a patent on the active ingredient to deny regulatory approval since 1994.Footnote 67 China adopted patent linkage in 2019 and is also required to provide patent linkage as a result of a 2020 FTA with the United States.Footnote 68 Taiwan, Ukraine, and United Arab Emirates also provide patent linkage.Footnote 69 So, in total, there are more than a dozen countries that provide patent linkage, or must provide patent linkage pursuant to FTAs,Footnote 70 as well as some countries that adopted patent linkage without a specific FTA.Footnote 71 In addition, there are some countries that do not formally provide patent linkage, but have informal measures such as requiring applicants to indicate a proposed generic is not protected by patents.Footnote 72
Implementation of patent linkage varies much more than data exclusivity. For example, although the United States has a relatively transparent system for patents that are linked to generic drugs, with a public list of patents associated with approved drugs, it does not for biologics.Footnote 73 Other countries treat generics and biologics the same for patent linkage but may have no public information available for potential generic manufacturers to know whether there are associated patents.Footnote 74 Also, although countries may provide a system for adjudicating whether patent(s) are valid and infringed, this can happen in traditional court systems, or through an administrative procedure that may involve regulatory authorities.Footnote 75 In addition, the stay of regulatory approval of the follow-on generic can vary substantially – up to nine months (South Korea), thirty months (United States), or even indefinite (Australia).Footnote 76 Although the potential stay in Australia is indefinite, other aspects of its law promote approval of follow-on drugs. Notably, if the follow-on applicant certifies that it will market the drug in a manner that will not infringe, the patent owner is not notified, and no stay of approval will occur.Footnote 77 In addition, even if the patent owner is notified, that only happens after approval of the follow-on (instead of upon receiving it), such that there is no undue delay in grant of marketing approval.Footnote 78
Some countries have measures in their patent linkage system that aim to limit abuse by patent-owning companies. Some countries do not permit companies to add patents after the initial application for approval.Footnote 79 Some countries impose penalties for false and misleading action by the patent owner.Footnote 80 In addition, some countries provide an incentive for a generic applicant to challenge weak or irrelevant patents by providing a short period of exclusivity as the only generic in the market.Footnote 81 However, this would not be an incentive in markets where prices of follow-on drugs are regulated. Even if prices are not regulated, the utility of this provision has been undermined by anticompetitive agreements whereby initial challengers are paid by the originator to not enter the market for a period of time.Footnote 82
2 Exploring the Intersection of Regulatory Protections and International Obligations
This section explains the IP obligations under TRIPS that are not previously discussed, proposed and actual waiver of TRIPS obligations to promote access to needed COVID treatments, and how these reflect incomplete understanding, or at least failure to fully address these regulatory protections. Although there are FTAs that require regulatory protections, they are not specifically discussed here since there have been no proposals to waive these FTA provisions. This likely reflects a strategic decision to first address the international agreement that applies to most countries, especially since some countries believe that TRIPS requires data exclusivity.
A International Obligations: TRIPS
Of particular importance to the issue of medical treatments, TRIPS requires all countries to provide minimal levels of patent protection in all fields of invention, including drugs.Footnote 83 Although TRIPS requires that inventions be patented and subject to enforcement, there are exceptions from patent rights: a compulsory license and a “limited exception.” Since the “limited exception” under TRIPS has been narrowly interpreted thus far,Footnote 84 a compulsory license to usual patent rights is the primary flexibility for minimizing the TRIPS requirement that patents must be granted on medical treatments. Consistent with prior international laws, TRIPS permits governments to issue compulsory licenses of patents which essentially permit the government to grant anyone the right to use a patented invention, subject to government-dictated royalties.Footnote 85 However, TRIPS imposes additional conditions, including that they must be mostly for domestic use.Footnote 86 In addition, after members realized that compulsory licenses were of no utility for countries that lack inadequate capacity to domestically manufacture drugs, TRIPS was amended to permit compulsory license for export to such countries with even more conditions.Footnote 87
An important issue is the consequence for failure to comply with TRIPS. There is a WTO dispute settlement process that can mandate a country to bring its laws into compliance or else face sanctions that can include withdrawal of WTO benefits.Footnote 88 Member states use this dispute process infrequently, likely due to fear of an undesirable ruling. However, the Global North has often suggested violations of TRIPS and based on this exercised unilateral pressure on countries. For example, there have been no formal WTO challenges concerning compulsory licenses, but the United States and European Union have repeatedly criticized use of these licenses and even done so during COVID.Footnote 89
B Proposed and Actual Modification of TRIPS Requirements for COVID
After the Global North engaged in vaccine nationalism by pre-ordering many more vaccines than needed, and companies were unwilling to license adequate numbers of manufacturers, India and South Africa proposed waiving IP obligations under TRIPS so that countries could create COVID vaccines.Footnote 90 Modification of TRIPS does not automatically change domestic IP laws. But modification can permit nations to modify domestic laws without international liability under the WTO and hopefully also without unilateral pressure from other countries. This section explains the original proposal, a counterproposal by the EU, and the ultimate agreement as background to understanding the extent to which they would impact regulatory barriers.
India and South Africa Proposal: Waive Multiple TRIPS Obligations to Address COVID
The original TRIPS waiver proposed a broad exemption from multiple provisions of TRIPS for prevention, containment, or treatment of COVID-19, which was later clarified to include vaccines, treatments, diagnostics, and personal protective equipment for three years from the date of the decision.Footnote 91 The TRIPS provisions that would have been suspended during this time period included all the patent provisions and trade secrets, including protection of undisclosed data submitted for regulatory review from “unfair commercial use.”Footnote 92 This proposal was suggested by South Africa and India but had broad support from developing countries, as well as heads of state and policymakers.Footnote 93 The United States also supported this, but only for vaccines.Footnote 94
EU: TRIPS Compulsory License Clarification
In June 2021, the EU sent a communication to the WTO that it believed voluntary licenses were most effective to increase production, and beyond that, it proposed use of compulsory licenses and suggested language to explain their use for COVID-19. The EU suggested clarifying that:
the COVID-19 pandemic is a national emergency, such that waiver of prior negotiation with patent owner is not necessary;
remuneration for licenses “should reflect affordable price.”Footnote 95
Although these statements may seem helpful, they do not add anything. A global pandemic clearly satisfies a national emergency under the existing TRIPS agreement, such that no prior negotiation is necessary. Moreover, even if there was any controversy concerning what constitutes a national emergency, each WTO country has the right to decide for itself.Footnote 96 In addition, TRIPS only requires licenses to provide “reasonable compensation,” so it already permits affordable prices; for example, India permits compulsory licenses to be issued if prices are unaffordable.Footnote 97
Limited TRIPS Waiver
In May 2022, the WTO circulated a draft text to all member countries based on language that was negotiated by South Africa, India, the United States, and the European Union in March 2022.Footnote 98 Some supporters of the original proposal strongly objected to this text as unduly narrow, with over 100 organizations urging rejection of the proposal,Footnote 99 whereas industry claimed it was unnecessary and harmful.Footnote 100 In June 2022, the WTO membership adopted a limited waiver of one TRIPS patent obligation for COVID-19 vaccines.Footnote 101 This waiver is very limited because it only modifies a complicated and cumbersome provision to circumvent the usual TRIPS requirement that compulsory licenses must be predominantly for domestic use that has only been applied once.Footnote 102 Although this is a welcome change given the provision is wholly unsuited for emergency use, the waiver of this provision only applies to developing countries and even explicitly discourages countries with existing capacity to use the procedure.Footnote 103 This seems patently illogical in that developing countries in the best position to supply other countries with vaccines are encouraged not to do so.Footnote 104
C Examining the Intersection of TRIPS Modifications and Regulatory Barriers
Now that the individual TRIPS proposals and actual waiver have been introduced, this section shows how each incompletely addresses regulatory barriers beyond the obvious fact that additional waivers of TRIPS-plus obligations would be required to remove all international barriers.Footnote 105 But before discussing these, a few observations about the relevance of regulatory barriers to the Global South and Global North may be helpful.
Even though these proposals and actual waiver do not fully remove regulatory barriers, this is a nonissue in some countries. For example, neither South Africa nor India currently require data exclusivity or patent linkage. However, this may change; data exclusivity is proposed in the FTA between India and the United Kingdom currently under negotiation.Footnote 106 Moreover, even if South Africa and India are successful in resisting FTAs that require regulatory barriers, both will likely soon exist in China, which has been an important source of COVID-19 vaccines. In addition, there are other developing countries that could make follow-on treatments that are currently subject to these regulatory barriers, such as Mexico, Vietnam, and Chile.
High-income countries that have these regulatory barriers may reduce their flexibility to protect domestic citizens during a pandemic. For example, early in the COVID-19 pandemic there were inadequate supplies of the treatment remdesivir, such that many recommended that the United States use its domestic powers to override usual patent rights.Footnote 107 Although remdesivir was only approved for emergency use and thus not subject to data exclusivity, if it had been granted orphan drug exclusivity as its manufacturer had planned before public protest, that would have been an additional barrier.Footnote 108 Moreover, the statutory provision permitting the United States to override patent rights for government use does not provide for overriding regulatory barriers such as data exclusivity or orphan drug exclusivity.Footnote 109
India and South Africa Proposal
The original proposal to modify TRIPS requirements proposed waiving not only patent obligations, but also ones concerning undisclosed information that some have argued requires data exclusivity.Footnote 110 However, discussion of this proposal suggests that some countries failed to understand that data exclusivity can be a barrier. Countries that strongly objected to this proposal repeatedly noted that it would not be effective on several grounds, but data exclusivity was not one; rather, they suggested that voluntary or even compulsory licenses were adequate.Footnote 111 But licenses are ineffective in countries where there is data exclusivity without any exception, as developing countries noted.Footnote 112 In addition, many that opposed this proposal focused on the fact that a waiver of trade secret obligations under TRIPS would not help scale up manufacture of vaccines since removal of liability does not mandate disclosure of trade secrets.Footnote 113 That is true. However, data exclusivity is a bigger, largely undiscussed hurdle. Some countries may be able to mandate or encourage companies to share needed trade secrets.Footnote 114 Even without compelled disclosure, companies can develop an alternative method as underscored by South Africa’s successful creation of a method to make the Moderna COVID-19 vaccine.Footnote 115 In contrast, data exclusivity in most countries is an absolute legal barrier without any exception. The few countries known to have exceptions to data exclusivity, such as Malaysia, are not major sources of generic drugs.Footnote 116
EU Compulsory License-Only Proposal
The EU’s proposed clarification of compulsory license provisions does not address regulatory barriers at all. It completely ignores the fact that effective use of compulsory licenses could be blocked by the existence of data exclusivity or patent linkage. Accordingly, this proposal is a strong example of lack of recognition of data exclusivity as a barrier to making needed treatments.
This lack of recognition is somewhat surprising. The EU’s own data exclusivity laws have previously been a barrier to use of a compulsory license during the Avian flu pandemic; public health advocates suggested that the EU should amend its laws to create such an exception.Footnote 117 In addition, the EU is aware that data exclusivity can be a barrier since the EU has an exception to such exclusivity for compulsory licenses of drugs for export.Footnote 118 Since the EU has previously recognized data exclusivity as a barrier, its proposal could be considered an intentionally incomplete attempt to address the pandemic.
TRIPS Waiver for COVID-19
Although the final June 2022 waiver (as well as the leaked March 2022 text) is better than the EU proposal in explicitly noting that the provision some argue to require data exclusivity should not bar regulatory approval of subsequent treatments, its utility is limited.Footnote 119 First, the waiver seems to improperly suggest that a pandemic is a unique situation for which article 39(3) should not be a barrier, rather than that this provision should never be interpreted to require data exclusivity.Footnote 120 Moreover, this waiver does not alone eliminate regulatory barriers adopted in domestic laws. Failure to consider that developing countries may be barred from effective use of the waiver due to data exclusivity mandated by TRIPS-plus agreements is a significant omission. Although some countries such as India and China could make vaccines, the waiver explicitly discourages countries with capacity from doing so. In addition, China has both data exclusivity and patent linkage and has proposed data exclusivity.
The waiver is also inadequate for excluding countries of the Global North that could grant compulsory licenses to export drugs and vaccines – but for which such licenses could be stymied by regulatory barriers.Footnote 121 Canada, for example, is completely excluded from using the new waiver of the usual complex compulsory license procedure for export. Canada is notably the only country that has ever issued a compulsory license for export in the over twenty years that TRIPS has permitted this to occur. And, while a Canadian company has agreed to provide Bolivia with COVID-19 treatments, due to lack of amendment of Canadian laws to permit such a license for those treatments, no shipment has occurred.Footnote 122 Moreover, although Canada’s law permits an exception from data exclusivity for such licenses, there is no exception from patent linkage, which Canada must provide pursuant to an FTA.Footnote 123
3 Looking Ahead
There are several things nations should do domestically to reduce regulatory barriers to accessing treatments during a pandemic. Since data exclusivity and patent linkage can impose barriers to timely access to lower-cost treatments, these should be avoided if possible. If that is not possible, then adopting patent linkage that simply provides notice to the patent owner and an exception to data exclusivity would be preferable.
At the international level, nations should avoid new agreements or unilateral pressure to mandate data exclusivity or patent linkage. Although this may seem obvious, it is very important considering that available generics for the world could quickly change if India adopts one or both protections. Also, to the extent that there are existing international agreements imposing commitments, nations should create exceptions.
The above steps should be helpful to promote access to medicine in future pandemics as well as non-pandemic circumstances.
