Oppositions made simple How to start: Leena Menghaney, MSF Access Campaign
1987: first ARV AZT1996: TRIPLE HAART THERAPY 2000: Glaxo Blocks Access To Lamivudine/Zidovudine in Ghana In letters to a drug distributor in Ghana and an Indian generic-drug maker, Glaxo said sales of generic versions of its drug, Combivir, in Ghana would be illegal because they would be violating company patents. As a result, the Indian company, Cipla Ltd. of Bombay, has stopped selling its low-cost version in Ghana, a small country in West Africa.

Globalisation of Patent Rules • 1995 WTO Trade related aspects of intellectual property rights agreement (TRIPS) • “minimum” standards of protection of intellectual property rights • 20 year patents on pharmaceutical products • No differentiation between lifesaving medicines and trivial goods • 2005 Indian amended its patents act to be compliant with TRIPS and starts to grant product patents (transition period ends).

Innovation in decline? patent protection has increased over the last 20 years, but the mean innovation rate has fallen Only 153 out of 1,035 new-drugs approved by the FDA during a 12 year period from 1989-2000 were for highly innovative drugs – medicines that contained new active ingredients and also provide significant clinical improvement. (NIHCM Foundation, 2002) Only 68 (5.9%) out of 1,147 newly patented drugs appraised by the Canadian Patented Medicine Prices Review Board between 1990 and 2003, met the regulatory criterion of being a breakthrough drug – the first drug to treat effectively a particular illness or which provides a substantial improvement over existing drug products. (Morgan et al, BMJ 2005) 68% of 3,096 new products approved in France between 1981 and 2004 brought ‘nothing new’ over previously available preparations. (Prescrire International, 2005)
Prevention is better than cure 3 steps Law/guidelines setting the patentability criteria Local examination – law provides for examination of every application Pre - Grant Oppositions
Examination system weeds out patent applications that should not be granted
Efforts to stop evergreening: India: Section 3(d) stipulates that the following shall not be treated as an invention within the meaning of the Act: “ the mere discovery of a new form of a known substance which does not result in the enhancement of the known efficacy of that substance or the mere discovery of any new property or new use for a known substance or of the mere use of a known process, machine or apparatus unless such known process results in a new product or employs at least one new reactant.” Explanation.—For the purposes of this clause, salts, esters, ethers, polymorphs, metabolites, pure form, particle size, isomers, mixtures of isomers, complexes, combinations and other derivatives of known substance shall be considered to be the same substance, unless they differ significantly in properties with regard to efficacy

Novartis patent application on life saving cancer drug – CPAA files opposition in 2005 Glivec’s base compound, Imatinib mesylate, was patented in 1993 and was not eligible for an Indian Patent because India joined the WTO only in 1995.
Result of CPAA’s opposition Jan 2006 • Patent for Glivec rejected • Generic versions of Glivec were once again available in the Indian market at affordable prices
MSF worried But since January 2005, India is obliged to grant patents on medicines the source of HIV medicines may dry
MSF pharmacist: Generic pipeline All these needed ARVs will be at risk of production if patents are granted
Prognôsis A granted patent in India for an essential drug (including Antiretrovirals) will block generic production by Indian companies and make drugs either unavailable or unaffordable (or both) across the developing world Partnerships: PLHIV networks, legal AID groups and MSF need to work together on opposing HIV medicine patent applications
Patent Applications in India US received 288K patent applications in 1999
Patent Filing Trends in India • Major Increase in the number of patent applications filed at the Indian Patent Office (IPO) • PCT is the favorite filing route • ~60% applications filed with the IPO were national phase filings under PCT • Majority of filers are foreign residents (Bayer, Gilead) Patent Filings at the IPO Source: Annual Reports of the IPO Source: Annual Reports of the IPO
Searching Indian Patents – A BIG Challenge • Opposition dependent on information available. But how does patent office manage publication in India: • no searchable database to identify applications (reduced to manual searching through thousands of patent applications) • Publication of only abstract. requirement of publication of patent specification deleted making it difficult to oppose effectively. • Information only available after visiting four patent offices in Mumbai, Delhi, Kolkata and Chennai (no centralised system) • Refusal to provide examination report Access to examination report available under USPTO & EPO • Refusal to provide copies of patent decisions/case law (trademark decisions are available in journals) under sec 153, rule 134 f). How we did it : • Manual procurement of patent copies from the Indian Patent Office • Need to submit request and fees at one of the four patent office branches where the application was filed (involves travel time & cost) • Regular follow-up required to obtain the copy of the patent application • May take three to four weeks for one application
Ex. of AZT+3TC patent application « a pharmaceutical composition and a method of inhibiting human immunodeficiency virus (HIV) is disclosed which comprises administering to an HIV infected patient a homogenous composition of lamivudine, zidovudine and a pharmaceutical glidant in an amount which achieves antiviral efficacy »
Efforts to stop evergreening Not all patent applications are valid. Many patent applications are for a new use of an old drug, or simply for derivatives of old drugs or combinations of old drugs. (TRIPS requires patent protection for ‘inventions’) E.g. AIDS drug patent applications: • a fixed dose combination of lamivudine/zidovudine used in the treatment of HIV/AIDS: not a new invention but simply the combination of two existing drugs. Status of application - Withdrawn • tenofovir disoproxil fumarate (TDF), a key AIDS drug: forming a salt (fumaric acid) out of an existing compound (tenofovir disoproxil), is common practice within the pharmaceutical industry, and should not be considered a new invention. Status of applications - Opposed II. Any person can oppose the grant of a patent application
Combivir patent opposition – Indian and Thai groups hold protests on the same day, issue joint press release… …GSK announces withdrawal of Combivir patent application 7 August 2006: PLHIV protest outside GSK offices in Bangkok, Thailand. 7 August 2006: Indian groups demonstrate outside GSK offices in Bangalore, India.

The basic patents on Nevirapine (NVP) were applied for by BoehringerIngelheim in November 1990, and are due to expire in November 2010. BI also applied for a patent on the hemihydrate form of NVP, used in the suspension in 1998, which is due to expire 2018. Additionally, BI applied for a patent on the extended release formulation of nevirapine in 2008, which is due to expire in 2028. India has a specific provision in its patent law that does not grant patents on minor changes to existing medicines. It allows any person to file a technical opposition Legal safeguards: Prohibition of Evergreening & right to file oppositions
STAGES OF EXAMINATION FILING OF APPLICATION PROVNL. / COMPLETE PUBLICATION OF APPLICATION • PROMPTLY AFTER 18 MONTHS REQUEST FOR EXAMINATION • WITHIN 48 MONTHS FROM F.D. EXAMINATION-ISSUE OF FER 3rd Party Representation • ALL OBJECTIONS TO BE COMPLIED WITHIN 12 MONTHS REJECT/GRANT OF PATENT OPPOSITION • WITHIN 12 MONTHS Decision of Controller Appeal Revocation/Amendment Appellate Board
Strategy for India : Identifying Barriers Shortlist drugs • Use organisations like MSF, Pharmacists, other treatment providers like CPAA Study US/EP/PCT patent families of short-listed drugs • As almost 80% patent filers are foreigners, there are good chances that the patent would have patent applications in US/EP/PCT • Since full texts of all granted patents are not available online, and manual procurement of patents takes time, PCT, US, EP documents help in quick assessment Order full text of patent applications/patents from patent office • You can ask a patent agent to find • You can directly ask patent office for equivalent patent application • Protests, Right To Information laws, prominent leaders can help Order full text of patents from relevant branch of the IPO • Note the branch of the IPO in the application number, and order the full text from that branch only • Presence of local vendor helps in regular follow up with the IPO and quicker delivery of patents
Patents Not Absolute • Patent applications can be opposed during examination process (pre-grant oppositions) • Patents can be challenged after grant (post grant opposition) • Patents considered valid until challenged (ex: Thai patent on ddI
Message: Why are pre-grant oppositions important? • Pressure on patent offices to do thorough analysis of patent applications • TRIPS does not define: • inventions • patentability criteria • Great majority of patent applications are on new forms / improvements of known compounds • Rejection means access to generic medicines which are affordable
Check legislation • Does your country examine application locally and then • Some countries have no pre-grant opposition procedure but have post grant • Some countries have pre-grant but no post grant (Thailand) • Some countries have both (India) • Some countries have neither (South Africa) • Some countries grant opponents right to be heard (India) but others do not (Brazil)
Growing movement – SA, Thailand, Argentina, Philippines - Examination system weeds out patent applications that should not be granted. Direct benefit with earlier expiry of patents on ARVs. Compulsory licensing China - key announcement of procedures India – applications by generic competitors South Africa – reforms needed
