Innovative pharmaceutical companies have rapidly invented new medicines to fight against chronic conditions and notorious diseases such as AIDS that have plagued the worldwide population. Along with this innovation, however, emerged a lack of accessibility caused by pharmaceutical companies' ever-rising drug prices that are prohibitive to the poorest countries, which coincidentally have some of the sickest populations. While there are legitimate arguments to both sides on whether the increase in drug prices is a necessary evil, no one can dispute the burdens it places on poor populations.
Even in the United States, many Americans have resorted to filling their prescriptions with drugs from foreign countries. In fact, prices for prescription medication are continuing to rise above the inflation rate. Seeing as how the U.S. boasts one of the richest economies in the world, it is not surprising that one third of the worldwide population does not have any access to essential medication.
This research guide will focus on legal and economic factors surrounding the global problem of gaining access to innovative drugs. The paper will begin with some background history of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), leading up to the most recent modification that was adopted in Hong Kong on December 18, 2005. This discussion is necessary to understand the obstacles against providing access to essential drugs despite the compulsory licensing provision that was passed specifically for that purpose: to help provide essential drugs to those that could not otherwise afford them. The analysis will then consider reasons that support and oppose expanding the compulsory licensing provision to hurdle those obstacles. The analysis will show that the benefits of providing essential medication outweigh the risks of lost capital gains and counterfeit drugs. Finally, the research guide will cite several solutions that have been suggested by others and propose further research on their feasibility.
A. How TRIPS Formed a Marriage between Intellectual Property Law and the International Trading System
Prior to 1994, intellectual property law and international trade policies were essentially separate entities that were very limited in force and scope. The earliest treaties that related to intellectual property, namely the Paris Treaty and Berne Convention, focused primarily on preventing nations from enacting discriminatory intellectual property laws. Trade negotiations revolved around tariff and trade barrier reductions. In 1994, mounting pressure from the entertainment, pharmaceutical, and high-tech industries culminated in a major shift in international trade policy during the Uruguay Round of the General Agreement of Trades and Tariffs (GATT). At its conclusion, the World Trade Organization (WTO) was established to enforce international trade agreements and the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) was adopted.
So how did TRIPS marry intellectual property law with international trade regulations? Part I of the TRIPS Agreement reiterates adherence to the non-discrimination principles of GATT: "national treatment" and "most-favored-nation." Under these principles, Part II adopted the following intellectual property agreements: Paris Convention, Berne Convention, Rome Convention and the Treaty on Intellectual Property in Respect of Integrated Circuits. Parts III-V contained minimum requirements of intellectual property rights (IPRs), procedures, and mechanisms for dispute settlement.
Taking a step back, there are two Articles in Part I of the original TRIPS Agreement that particularly concern the pharmaceutical industry. Article 7 states that protection of intellectual property rights should be for the purpose of promoting innovation "in a manner conducive to social and economic welfare, and to a balance of rights and obligations." However, Article 8 opens the door to the controversial issue of suspending intellectual property rights for the purpose of public health and socio-economic need. Furthermore, Part VI contained provisions that allowed flexible transition periods for lesser developed countries to come into compliance. Still, the original TRIPS agreement left many ambiguities as to when and how WTO members may circumvent intellectual property rights to gain access to essential drugs or whether holders of intellectual property rights could prevent subsequent import or export of their product once it they have placed it in the market. TRIPS essentially did three things: (1) required WTO members to subject themselves to a minimum standard of protection for IPRs in order to avail themselves of the benefits of GATT, (2) gave WTO jurisdiction for resolving disputes related to intellectual property, and (3) provided procedures and remedies for dispute resolution.
The key in evaluating the policy trend of TRIPS in relation to the pharmaceutical industry is to look through the lens of its Article 7 objective to balance two competing interests: promoting innovation of new drugs and providing access to these drugs. For example, nations with weak economies and public health crises want medication for their people while innovative pharmaceutical companies want to protect their temporary exclusive rights in order to recoup their investment and maximize profits. At that time, the original TRIPS agreement took on a utilitarian posture. It placed more emphasis on promoting innovation than on providing access to essential drugs, thereby favoring member nations that enjoy the majority of pharmaceutical innovation. Recognizing this inequity, the WTO decided to place more emphasis on public health.
In 2001, the WTO Ministerial Conference officially initiated the Doha Agenda with a declaration [hereinafter Doha Declaration] that acknowledged the need to recognize a sovereign nation's right to protect public health, even at the expense of intellectual property rights. Namely, the Doha Declaration affirmed a sovereign nation's authority to grant compulsory licenses during national emergencies and to define what constitutes a national emergency. A country that was suffering a major epidemic could compel licensure for domestic production of patented medication that they could not otherwise afford.
Still, the Doha Declaration fell short of its objective to "promote access to medicines for all." Even with a compulsory license, many countries with severe health epidemics did not have the means or capacity to manufacture drugs. Nonetheless, TRIPS required that the majority of manufacture and sales resulting from compulsory licensing must be limited within the domestic market. Furthermore, the license was non-assignable; a country in dire straits could not assign a compulsory license to a nearby country that had adequate capacity to manufacture and sell generic versions of the drug at an affordable price. Recognizing these shortcomings, the WTO met again in 2003 to continue negotiating on the Doha Agenda at the Fifth Ministerial Conference in Cancun. There, they passed the Implementation Decision which extended compulsory licensing provisions by temporarily removing limitations on exports of drugs under a compulsory license to countries that could not manufacture drugs themselves.  This decision was adopted by the General Council in consideration of the Chairperson's statement, in which he reassured the members that compulsory licensing is to be used in good faith and stressed the need to prevent diversion of supplied drugs.
In 2005, during a ministerial conference in Hong Kong [hereinafter Hong Kong Declaration], the General Council agreed to make the Implementation Decision permanent by amending TRIPS. Now, a country that is eligible for compulsory licensing but lacks sufficient drug manufacturing capacity can import drugs from an exporting member that is also operating under a compulsory license, subject to certain conditions. That is, the TRIPS Council must be notified before a cross-border compulsory license can be issued, but approval is not required. However, remedial measures to resolve conflicts from alleged abuse of the system remain vague. Thus, the TRIPS Council's sentiment, with respect to their goal of striking a balance between the competing Article 7 interests, has shifted from favoring IPRs to favoring wider access to drugs for the benefit of public health. There are, however, uncertainties as to whether the amendment will achieve its purpose.
Despite the WTO's tremendous efforts to create a diplomatic compulsory licensing system that improve access to prescription medicine, the latest TRIPS amendment did not resolve several existing issues and even created some new concerns. Particularly troublesome are the lack of specific requirements in determining eligibility for compulsory licensing, risks of arbitrage and production of counterfeit drugs, and whether TRIPS, in its current construction, will actually help developing countries gain accessory to essential drugs..
On its face, the compulsory licensing provisions contain a number of vague terms that are intended to broaden the scope, but instead will most likely increase the transaction costs of assigning a valid compulsory license. These ambiguities have been articulated by Vishal Gupta, who suggests some objective approaches in determining valid circumstances for compulsory licensing.
The problem is that the scope of eligible diseases, drugs, and nations are undefined. The lack of specificity was intended to give least developed countries flexibility to decide for themselves what constitutes a public health emergency and minimize delay in accessing essential drugs. However, it may actually create more controversy because any nation can, in theory, declare a public health emergency for questionable reasons to assign compulsory licensing for any patented drug. Furthermore, TRIPS requires countries utilizing compulsory licensing to pay "adequate remuneration" without specifying a method of calculation. Perhaps, lists of valid diseases, drugs, and nations that are calculated and updated annually by a nonpartisan body can prevent such tension.
Arbitrage, also called "parallel trading" and "diversion" within the context of international trade, is a problem that manifests when a buyer purchases products at below market price and subsequently exports the products to another market where they are priced higher. In terms of economics theory, arbitrage essentially shifts surplus from the producer to the consumer. A good example of this practice occurs between Canada and the United States.
The general consensus is that pharmaceutical arbitrage poses a danger to innovation because it undermines already-existing efforts to provide affordable drugs through differential pricing and reduces the revenue needed to keep pharmaceutical research and development a profitable investment. However, Kevin Outterson, J.D., has written a fantastic article suggesting that arbitrage in the pharmaceutical industry is not a serious threat to innovation, and may even benefit society by making drugs more affordable. Unlike many articles that limit the scope of analysis to economics principles when discussing the effects of arbitrage, Outterson consistently weighs his economic analyses against social welfare.
Still, this is currently the hottest topic for economists regarding whether providing access to drugs through compulsory licensing will have a detrimental effect on the market, and consequently hinder innovation - perhaps because the U.S. Congress recently passed the Pharmaceutical Market Access and Drug Safety Act in 2004. There is a wide range of opinions that speak to how the new law will affect the pharmaceutical market. At the extreme is the view that legalizing re-importation of drugs into the U.S. will severely damage not only the pharmaceutical market in the U.S., but also the global market. Another view predicts that the law will not significantly improve access to cheaper drugs because rational pharmaceutical companies will respond by not selling their products in markets from which Americans are allowed to re-import. And yet another opinion reasons that re-importation should not significantly harm the drug market because pharmaceutical companies will just ramp up their marketing efforts to sell higher quantities; after all, they have a history of successful marketing such that consumers prefer to buy designer brand drugs over generic equivalents.
Adding to the controversy is the lack of uniform rules for protecting the rights of patent holders. That is, TRIPS does not address whether patent rights are exhausted once patented products are sold into the market stream. In fact, TRIPS does not currently mandate its members to adopt any specific measures to prevent arbitrage as a pre-condition to compulsory licensing. There is, however, a provision requiring drugs made under compulsory licenses to be designated by distinctive packing, colors and shapes to help quickly detect acts of arbitrage and identify the source of production or export. The distinctive look requirement can also help the WTO adopt a uniform rule of exhaustion for pharmaceutical products that are manufactured under a compulsory license. For now, the WTO requires members who import and export pharmaceutical products under a compulsory license to send notice of the details of the transaction, such as name of the drug, name and address of the manufacturer, name and address of the importer, quantity, and duration. However, importers are only expected to take "reasonable measures" to prevent re-exportation.
A similar risk to arbitrage that is frequently included in compulsory licensing discussions is the production and export of counterfeit drugs with no therapeutic value. This is perhaps the most severe threat to public health as people will not be able distinguish a counterfeit drug by its physical appearance. Pharmaceutical companies argue that compulsory licensing with no clear standards against arbitrage will increase the probability that consumers in developed countries will inadvertently purchase dangerous substitutes in efforts to purchase cheaper drugs.
According to Outterson, however, empirical evidence tends to show that the threat of counterfeit drugs is overstated for several reasons. First, he points out that counterfeit drugs should be distinguished from functional, generic copies of patented drugs. Narrowing counterfeit drugs to non-functional copies that lack the active ingredient, he then cites authority claiming that the majority of the non-functional counterfeit drugs are produced domestically. Furthermore, he reasons that as drug prices fall, there will be less incentive for criminals to produce counterfeit drugs because the of the unattractive profit margin. Moreover, patented drugs, not cheap generics, are the target of counterfeiters, so increased availability of low-cost generic drugs would actually dissuade counterfeiting.
TRIPS now extends compulsory licensing privileges so that nations without manufacturing capacity can import drugs. However, evidence suggests that this provision will fail in its efforts to improve access to patented drugs. Amir Attaran, an immunologist and lawyer, makes this argument based on history of compulsory licenses. According to history, compulsory licensing has rarely been used for any reason. The explanation for the under-use, or rather lack of use, lies in international politics. Many developing countries want to attract future investment and technology; therefore, they choose not to issue compulsory licenses because it might show a lack of respect for intellectual property rights and consequently decay trade relations or scare off investors.
Furthermore, if countries are reluctant to issue compulsory licenses for the benefit of their own people, it is even less likely that they will use this measure to assist another country that lacks manufacturing capacity. In other words, the Hong Kong Declaration permanently amended TRIPS so that countries with limited manufacturing capabilities could import drugs because nations that issue compulsory licenses no longer have to manufacture drugs for a predominantly domestic use. The problem in achieving that purpose is that it relies on countries with manufacturing capacity to first issue compulsory licenses.
Perhaps now that the Hong Kong Declaration permanently amended the compulsory licensing provisions, these concerns will become moot. It will be interesting to see whether the number of compulsory licenses issued will increase.
In order to maximize their profits, companies across industries utilize differential pricing schemes, sometimes more generally referred as price discrimination. The pharmaceutical industry is no exception and has engaged in differential pricing by segmenting the market based on political borders and income classes. Under this practice, the poorest countries were offered the lowest prices within the range but failed to successfully deliver essential drugs to the people.
Since the Implementation Decision was adopted in 2003, the potential threat of compulsory licenses has moved companies to voluntarily make proactive efforts to realistically make their drugs accessible. Some have dramatically lowered prices while others have offered voluntary, royalty-free licenses. And while governments have not yet issued compulsory licenses, Brazil, a middle-income country, has actively used it as a threat to negotiate lower prices for AIDS drugs.
In contrast, many still argue that the compulsory licensing provisions have not helped bring drugs to those in need. Some low-income nations like Thailand, Colombia, and South Africa have been pressured by powerful nations like the U.S. to adopt more rigorous intellectual property laws during free trade negotiations. Other countries simply lack coordinated efforts within the government or found the application process to onerous.
The emerging pattern tends to show that the leveraging capacity of compulsory licensing depends on the relative political strength of the licensing country. Considering the fact that most poor countries do not have political pull, it looks as though compulsory licensing and differential pricing negotiations in the near future will not make significant impact in improving access to medicine.
The following subsections explore potential solutions to the issues with the current TRIPS amendment. Each solution was proposed prior to the Hong Kong Declaration. While time may prove that some of these solutions are unnecessary, others deserve consideration despite the recent amendment.
As mentioned in the prior section, the Hong Kong Declaration has left significant ambiguities that, though well intended, may impede efficient use of compulsory licensing. Clarifying these ambiguities will not only improve efficiency in utilizing compulsory licenses but may also encourage nations to issue compulsory licenses without concerns of political backlash.
The most common suggestion is to develop and maintain a set of lists that universally recognize diseases that can be considered a threat to public health and drugs that are automatically eligible for compulsory licenses. This reduces tension between countries and time for governments to deliberate on whether granting compulsory licenses for certain drugs would be diplomatic.
Another suggestion is for WTO to adopt a uniform socio-economic model to determine whether a nation is eligible to grant compulsory licenses. Adopting a model prevents abuse and ensures that not just any nation can use compulsory licensing to gain cheaper access to drugs. One method is to conduct a benefit-detriment analysis that compares the monetary loss suffered by the pharmaceutical company with the aggregate social benefit. The WHO also periodically compiles and updates a comprehensive data set of socio-economic indicators relevant to the pharmaceutical sector that can be used to identify nations, drugs, and diseases that qualify for compulsory licensing.
Finally, the ambiguity concerning when patent rights are exhausted should be clarified. This is one area where ambiguity may be the lesser of two evils because penalizing rogue individuals or governments for engaging in arbitrage ultimately punishes the greater mass population that is in need of essential drugs. By requiring nations to take "reasonable measures" to prevent arbitrage, TRIPS implies that, at least in the international domain, patent rights are not exhausted by sales made through compulsory licensing. Still, the WTO should explicitly establish a default standard for countries that do not have a rule of exhaustion or at least define what can be considered an arbitrage violation with equitable remedies.
Another solution, proposed in a recent article by Outterson, is to establish a systematic buy-out mechanism for the patent rights to identified essential drugs with limitations to a particular geographic market. This would not only circumvent the controversial issue of granting compulsory licenses and provide drugs at production cost. Approximately 80% to 90% of the global sales of patented pharmaceutical products are made in 30 wealthy countries who are all members of the Organization for Economic Cooperation and Development (OECD). Conversely, the vast majority of the world population that suffers from chronic and infectious diseases lives in non-OECD countries, comprising greater than 84 % of the population. By selling drugs to non-OECD countries at production cost or generic prices, the public health benefit would substantially outweigh the lost revenue so as not to reduce incentives for pharmaceutical innovation.
In his recent article, Outterson outlines a three-step process for this buy-out mechanism. An eligible purchaser could be any entity from a government, to an inter-governmental organization (such as the WHO or WTO), to a philanthropic foundation (e.g., Gates Foundation). In many ways this mechanism is similar to compulsory licensing in that they are both forms of compensated takings, but there are a few key differences. First, unlike a compulsory license, a single patent buy-out does not have to be limited to a one drug and a specific country. Instead, one patent buy-out can be negotiated for a class of drugs (albeit for a single pharmaceutical company) that can be manufactured and sold a number of countries, thereby resulting in lower transaction costs than would occur for each compulsory license. Second, the purchaser would have exclusive rights to market and license the drug(s) in the negotiated region. In contrast to pharmaceutic2al companies whose objective is to maximize profits, the new owner of exclusive marketing and licensing rights can offer multiple non-exclusive, no-royalty licenses to generic drug manufacturers in order to generate a competitive market. Third, unlike compulsory licensing under TRIPS which requires royalty payments to the patent holder, the patent-buyout price would be determined by the net present value of expected future profits. This adds flexibility in financing the buy-out and is more attractive to pharmaceutical companies who, under compulsory licensing, would have had to later reconcile the number of drugs actually manufactured and sold in order to verify royalty payments.
The drawbacks to this proposal are loss of profit to pharmaceutical companies, increased risks of arbitrage to OECD nations, and potential for counterfeit drug manufacture under the guise of a generic. While it is irrefutable that market loss decreases incentives for innovation, careful design of patent buy-outs, safeguards against arbitrage as mentioned in II(B), and reduced burdens of compulsory licensing should provide adequate incentives for pharmaceutical companies to engage in negotiations. As also mentioned in II(B), the incentive for counterfeiting generic drugs is negligible. Patent buy-outs seem to be one of the most diplomatic alternatives to compulsory licensing, but more research should be conducted on availability of financing and buy-out terms that would attract innovative pharmaceutical companies.
One obvious method for improving access to patented drugs is to finance public pharmaceutical research. This way, patented drugs can directly enter the public domain. One proposal, by U.S. Representative Dennis Kucinich, is to finance pharmaceutical research through a set of competing publicly supported research centers and offer prize money for breakthroughs. Granted that this proposal was intended for application in the U.S. only, it still has merit. The notion is that as more patented drugs are directly placed in the public domain, pharmaceutical companies would be forced to compete with similar drugs that are already being sold in the market as generics, thereby driving down prices.
Applying the solution in a global setting, the key sponsors would be similar to those for patent buy-outs: individual governments, intergovernmental entities like the WHO, and philanthropic foundations. The best scenario would be funding through an intergovernmental entity so that research expenses can be shared equitably. Potential problems arise with sustained financing and for governments and intergovernmental entities, political interference.
Sustained financing is the first issue because projects such as these are not profit-making machines, and so their longevity is heavily dependent on their success. Without a stable source of funding, these research efforts run the risk of being run into the ground due to mismanagement or getting beat by a private institution on the way to filing a patent. This risk is especially high with government funded research as some may be required regular disclosures of incremental research findings.
Political interference will also be a risk in terms of management and direction of research. For example, some governments will forbid funding for research in certain areas such as stem cell research. Also, performance assessments are not measured by profit, so there is anger that research grants awarded to a research group may not always be based purely on merit. Notwithstanding these issues, a public international effort to compete with the pharmaceutical industry will send a positive message to the global community and may compel pharmaceutical companies to negotiate patent buy-outs. More research should be conducted on past experiences with publicly funded biomedical research.
Progress towards providing equal access for drugs has been slow. It is not yet certain whether more education and assistance in filing for compulsory licenses or whether TRIPS provisions can even help developing countries overcome the intimidation factors of powerful governments. Because cross-border compulsory licensing rights have been in effect for only three years, more observations need to be made before any assessment can be deemed accurate. I encourage those who are interested in this topic to either track the progress and new game strategies employed by developing countries under TRIPS or explore some of the concerns and potential solutions mentioned in this research guide.

The author concludes that developed and developing countries are better served by open markets and recommends the WTO to prohibit governments from blocking parallel imports.
Outterson, Pharmaceutical Arbitrage: Balancing Access and Innovation in
International Prescription Drug Markets, 5 Yale J. Health Pol'y, L. &
Ethics 193 (2005) - HIGHLY RECOMMENDED
This is a very comprehensive article that focuses on arbitrage in the pharmaceutical industry. In addition, it gives a fairly detailed explanation of how the pharmaceutical market functions differently from other goods markets and how the economics change between differential pricing and arbitrage. The author concludes that because the pharmaceutical industry is supra-optimal, the financial loss that would result from pharmaceutical arbitrage would be substantially outweighed by the gain in access. Other articles by this author are recommended as he is one of few authors that considers the effects on both the economy and social welfare.

Implications of The Pharmaceutical Market Access and Drug Safety Act of
2005, 12 New Eng. J. Int'l & Comp. L. 161 (2005)
This article runs an economic analysis the implications of legalizing importation of drugs from Canada. The author concludes differential pricing is essential to drug innovation and importation of drugs from Canada will have a detrimental economic impact on both foreign and domestic pharmaceutical industries. The author explicitly states that social welfare and public health considerations were excluded from the analysis.

This article is another take on the economic impact of legalizing importation of drugs from Canada. In conclusion, the author predicts that the law will not significantly improve access to cheaper drugs because rational pharmaceutical companies will respond by not selling their products in markets affected by the legislation. The author explicitly states that social welfare and public health considerations were excluded from the analysis.

This article was previously listed under "Arbitrage." However, this article also discusses the dangers of counterfeit drugs. He observes that empirical data indicates the vast majority of non-functional counterfeit drugs in the U.S. are produced domestically. This article also explains how the differential pricing is used in the pharmaceutical industry.

Project on Technology - Great website to find fairly recent
developments by country or region.
This website is dedicated to production of and access to knowledge. Recently, they have begun focusing heavily on access to medical technology. Their interface is very user-friendly because the page is organized by topic, geographic region, specific drugs, specific countries, pharmaceutical companies, and even specific topics. The only drawback is the lack of comprehensive, up-to-date news.
- TCS Daily - Good for learning
about recent strategies used by governments and industry in trade
TCS is for Technology, Commerce, and Society. This site believes in "free markets, open societies, and individual human ingenuity." Therefore, the articles will have some spin, meaning they do not support compulsory licensing. But the facts in the articles are quite accurate. This is a very modern, hybrid website where authors regularly write articles on recent global events and members (some of whom are industry experts) can submit their own articles and post blogs.

 Kevin Outterson, in a heuristic approach, argues that (1) a system dependent on voluntary differential pricing to deliver affordable drugs to poor populations is likely to fail and (2) the vast majority of pharmaceutical innovation takes place in a handful of countries, thus making it nonrival. Furthermore, he asserts that pharmaceutical arbitrage will not harm innovative pharmaceutical companies because the market is supra-optimal and challenges those who oppose this view to support their claims with transparency and allow the public domain to evaluate pricing and production costs.

 The articles that suggest compulsory licensing will be ineffective in providing access to innovative drugs were written prior to the Hong Kong Declaration.
 In an idealistic economic model, goods are sold at near production cost. However, businesses recognize that consumers are willing to pay more for products that have greater demand. Thus, companies use various analyses to determine the highest price that a customer is willing to pay. What results is the same product being sold at different prices to different buyers. This is a very crude description of differential pricing. For more information, please economics references.

 See Outterson, supra note 22 at 205.
 There are several reasons why differential pricing fails to provide access to patented drugs. First, transaction costs are high when prices are negotiated on a case-by-case basis. Second, pharmaceutical companies seldom, if ever, offered drugs at or below production cost. Id. at 227.
 There have been many dramatic price cuts since 2001, when the Doha Declaration first proposed cross-border compulsory licensing. However, these price cuts have not significantly increased access to drugs. In 2004, Merck granted a voluntary, royalty-free license to a South African drug manufacturer, perhaps to prevent South Africa from beginning the trend of exercising the right to issue a compulsory license. See Outterson, supra note 22 at 226-27.

 These additional protections, collectively called "TRIPS Plus" require things such as prohibiting generic manufacturers from using data generated by innovator companies in their licensing applications for five years after marketing approval and providing protections for new formulations of existing drugs in countries that traditionally do not recognize slight changes as innovation.
