16 The authors use the term “biogenerics” or “generic biologics” to include products that are determined to be “identical” and “therapeutically equivalent” by scientists, as well as products that are found to be “highly similar” and “comparable” (similar, comparable medicines are in the same product class and have the same therapeutic purpose, but the molecules cannot be scientifically characterized as identical and the product is not defined as therapeutically equivalent). Often a distinction is drawn between these two categories, with identical or equivalent products labeled “generics” or “biogenerics” and highly similar products called “biosimilars” or “follow-on biologics.” For the purposes of this paper and the sake of simplicity, the authors choose not to make a distinction between these two categories and to use the term biogenerics to refer to all of them. Technology and regulatory pathways for both categories of product are still developing, and the authors acknowledge no one has yet engineered or registered generic copies of any vaccine, and that it may be quite difficult to do. But it is possible the scientific know-how and the regulatory environment will evolve in coming years such that it will be possible to engineer and market generic HPV vaccines, which would in fact be called “biosimilar” or “biogeneric” products. The specific challenges related to engineering and registering generic versions of biologic products like the HPV vaccine will be discussed in greater detail in the text and footnotes of Section III.

17 At least one Indian vaccine-maker, Shantha Biotechnics, is currently attempting to engineer a low-cost second-generation HPV vaccine. Second-generation products are not generic imitations or copies of the original first-generation product (in the case of the HPV vaccine there are two first-generation products, Merck's Gardasil and GSK's Cervarix). Because second-generation products are not generics, but are new and different product albeit with the same therapeutic purpose, they have to undergo the full battery of safety and efficacy tests of the relevant regulatory authorities before being approved for sale. There is no guarantee that Shatha will be successful at developing this product, which some have estimated is not likely to be ready for marketing – if at all – until 2015 or beyond.

25 For example, in 1998, a coalition of pharmaceutical companies sued South Africa, alleging that its newly inaugurated Medicines Act, which permitted price-reducing, accesspromoting practices such as parallel importation and compulsory licensing, violated TRIPS. Public resistance and poor legal bases for these claims prompted the pharmaceutical manufacturers and United States to abandon this case. But this and other incidents underscored lingering conflicting understandings of TRIPS within the international community.

54 Some countries may also have regulations making it difficult to register a follow-on drug if the original is not domestically registered.

56 In countries with linkage rules (such as the United States), the drug regulatory authority will not approve a drug for sale if another party claims a patent on it. Drug Price Competition and Patent Term Restoration Act (Hatch-Waxman Act) of 1984, Pub. L. No. 98- 417, 98 Stat. 1585 (codified at 15 U.S.C. §§ 68b-68c, 70b (1994); Federal Food, Drug, and Cosmetic Act, 21 U.S.C. §§ 301, 355, 360cc (1994); Creation of Remedy, 28 U.S.C. § 2201 (1994); Issue of Patents, 35 U.S.C. §§ 156, 271, 282 (1994)). In other words, under linkage, a drug generally must be off patent before generics can be sold. A compulsory license in a linkage system would allow the regulatory authority to approve a generic drug for sale in spite of a patent.

In countries without linkage, the drug regulatory authority gauges only safety and efficacy. If a drug works safely for its intended purpose, it may be sold on the national market. Drug companies enforce their patents through the courts or other dispute systems (in much of Latin America, patent holders file medidas cautelares), but not necessarily before a generic drug reaches market. In countries without linkage, generics may be found on the market even though a patent is claimed. Generics on the market may mean the drug is not patented, or that the patent holder has not filed suit to remove the generics, or that the claimed patent is actually weak or invalid. A compulsory license in a system without linkage would protect generics already on the market, and generics that might come on the market later, from enforcement actions brought by the patent holder.

A compulsory license provides generics companies, patients and government agencies security, ensuring a patent holder will not be able to force the generic off market after patients and agencies have come to rely on its low prices. This security may also act as an incentive to attract more generics firms to market. Drug registration, marketing and distribution are expensive for low-capitalized generics firms, and firms may prefer to avoid the risk if a drug is on patent, particularly in smaller countries where there is less potential profit to be made. Compulsory licenses assure generics firms their investment will be protected.

57 According to the Health Canada and European government patent databases, some HPV patents may expire as early as 2012, but others are slated for 2016. For a general search of Canadian and European patent databases, see Canada, Patent Register Search Page, http://www.patentregister.ca (last visited Apr. 30, 2009); European Patent Office, About Patent Information, http://www.epo.org/patents/patent-information/about.html (see infra text accompanying note 65) (last visited Apr. 30, 2009). There may be other patents set to expire later, and there remains the possibility of patent “evergreening,” filing new patents on the same products for relatively minor changes, which could extend the patents considerably longer. Absent licenses, Merck and GSK will be able to use patents to block competition until all patents covering technology necessary to produce HPV vaccines expire.

58 Practically, even absent linkage, most generic vaccine makers might not apply for FDA approval so long as the originator products are patented. See Michelle Meadow, Greater Access to Generic Drugs: New FDA Initiatives to Improve Drug Reviews and Reduce Legal Loopholes, FDA Consumer, Sept.-Oct. 2003, at 14. But if there were a pathway to generic vaccine approval and no linkage, FDA approval would at least be technically possible as a strategy to assist worldwide registration, even if the U.S. market would not be available for sales.

59 New products receive eight years of data exclusivity, after which follow-on companies may file “biosimilar” applications. Biosimilars will not be approved for sale until another two years have passed. See generally Janie Mackay, bioLOGIC Europe 2007, 10 IDrugs 543 (2007). If the innovator also receives approval for new uses of the original product, this can add one additional year of data exclusivity, for a total of eleven years available exclusivity (8+2+1) following marketing approval.

66 The authority to license data is also implicit in the authority to issue compulsory licenses for patents, for what good would such licenses be if data exclusivity prevented registering generics in any event?

68 There are, however, public databases listing patents for the wealthy countries.

69 The FDA's Orange Book is an example, though notably, it excludes the HPV patents. The Orange Book lists patents for drugs approved under the Food, Drug and Cosmetic Act; but Gardasil was approved under the Public Health Services Act, which regulates most biologic drugs and vaccines.

70 In the United States, drug patent disclosure is a precondition of marketing approval. The Drug Price Competition and Patent Term Restoration Act of 1984 (more commonly known as the Hatch-Waxman Act) requires every person introducing a drug into commerce to file a new drug application (NDA) with the Food and Drug Administration (FDA). Drug Price Competition and Patent Term Restoration Act (Hatch-Waxman Act) of 1984, Pub. L. No. 98- 417, 98 Stat. 1585 (codified at 15 U.S.C. §§ 68b-68c, 70b (1994); Federal Food, Drug, and Cosmetic Act, 21 U.S.C. §§ 301, 355, 360cc (1994); Creation of Remedy, 28 U.S.C. § 2201 (1994); Issue of Patents, 35 U.S.C. §§ 156, 271, 282 (1994)). The NDA must include patent information–specifically, the patent numbers and expiration dates of patents that might reasonably be asserted in an infringement action. Drugs cannot be marketed until the FDA approves this application. Id. The FDA's Orange Book includes the submitted patent information in its Addendum, making it a little easier for generics manufacturers or health agencies to research patents held on critical medicines.

Here, entering CA2215834 reveals a Merck patent; entering CA2113712 reveals a Frazer/Zhou patent.

73 It will be easy to look up patents if every time an application is filed, a priority number of US19950423387 19950425 (corresponding to the HIV/AIDS medicine Kaletra) is entered in precisely that format. If, however, country codes, spaces and dashes are treated differently with each application – such that the same patent listed above could read “1995042338719950425” – or if the number is entered incorrectly, or if the numbers are not always entered into the database, or if the number sequences entered are pulled from different sources each time, such a search could become unreliable (note that a search for only part of the number sequence – for example, 19950423387 – should turn up results so long as the number was entered correctly in some form). Id. In such a case, the patent officer might have to employ one further creative method: reading the international patents for unique keywords that are likely to be listed in the national patent (some patent offices use this method). For example, U.S. or European patents might include specific terms describing a drug's chemical makeup that are distinguishable from other drugs to an informed reader. These terms could be entered into a national database as a keyword search. It may be helpful if someone with a background in chemistry or pharmaceuticals is available to assist.

74 This does not necessarily mean the patents are valid, but assessment of the validity of the HPV patents is beyond the scope of this paper. For health policy planning purposes, the HPV patents sharing the aforementioned priority numbers have not been discredited.

Also recall some patents related to key medical products, such as those only covering the product when used in combination with a tangential product, may not create barriers to generic competition. That is, if a patent specifically protects only the combination of Medicine A and Medicine B, then it does not protect Medicine A used without Medicine B. Generics companies are free to market Medicine A unless a separate patent specifically protects Medicine A, its essential components, or exclusive manufacturing process. This point is relevant because patents held by little known companies sometimes surface in patent searches, claiming use of a variety of established medicines in combination with a separate, lesser known product. These patents cannot control use of the established products except as used in conjunction with their own. In other words, not every patent naming a medicine somewhere in its text actually prohibits competition with that medicine.

76 The World Intellectual Property Organization's (WIPO) online portal is http://www.wipo.int/portal/index.html.en. Countries should generally consolidate their international obligations (TRIPS if already applicable, trade agreements, etc.) in the domestic law, but occasionally this might not happen. For example, Ecuador has its own Law on Intellectual Property (1998), with distinct terms, but also is a member of the Andean Community, which applies a Common Intellectual Property Regime (2000) for its members. Arguably, the two are not consistent (see, e.g., differences in the compulsory licensing chapters), but Ecuador has not amended its law to account for any differences. See Treaty Creating the Court of Justice of the Cartagena Agreement, art. 1, March 10, 1996 (discussing direct applicability of Andean Community decisions in member countries), available at http://www.comunidadandina.org/ingles/normativa/ande_trie2.htm. A non-official translation of Andean Community Decision 486: Common Intellectual Property Regime is available from the Andean Community at http://www.comunidadandina.org/ingles/normativa/D486e.htm. Ecuador's Law on Intellectual Property can be accessed through the World Intellectual Property Organization Collection of Laws for Electronic Access portal.

77 In some cases, no clear procedures for issuing compulsory licenses are specified in the law. Government officers may be hesitant to initiate the licensing process without clear protocol guiding their decisions. For these reasons, it makes sense for governments to implement public health-friendly compulsory licensing regulations where they do not yet exist. The danger is implementing regulations that unnecessarily restrict government action. Regulations should ideally specify several possible clear paths to compulsory licenses, enabling anyone to request licenses and not limiting authority to grant them to any single government agency.

78 See WTO, TRIPS and Public Health, supra note 32. Note that while some countries may restrict the grounds for issuing compulsory licenses to situations of emergency or national security, most do not, and WTO rules leave the grounds entirely open. Id.

79 TRIPS, supra note 23, art. 31(b). Licenses issued to remedy anticompetitive practices are another exception. See id. at art. 31(k).
