A new online resource for civil society and patient groups in developing countries to challenge unwarranted drug patents was launched by Médecins Sans Frontières (MSF). The Patent Opposition Database comes as many developing countries face dramatically high drug prices because patents block the production of lower-cost generic versions. The Patent Opposition Database is accessible at patentoppositions.org
“Drug companies routinely apply for patents or are granted monopolies on medicines even when these aren’t actually deserved. It’s a myth that every patent application that is filed is valid. When you look closely, a patent application may fail one or more of the legal tests it needs to pass. The idea behind this database is to help civil society and patient groups stop unwarranted patents from blocking people’s access to more affordable medicines,” said Michelle Childs, Director of Policy Advocacy for MSF’s Access Campaign.
A ‘patent opposition’ is allowed under international trade rules as a way to keep checks and balances on pharma patenting. In countries where they are allowed, like Thailand, Brazil or India, patent oppositions have successfully prevented undeserved patent monopolies from being granted and allowed generic competition to bring the price of medicines down.
“Successful patent oppositions by civil society in India have enabled us to use more affordable generic versions of key HIV medicines in our treatment programmes,” said Dr Esther C Casas, MSF HIV/TB Specialist for Zimbabwe.
“Due to the volume of applications, local patent examiners can miss information and grant unjustified patents. Just putting two or three separate pills into one, or using known industry practices to formulate a drug, should not be considered innovative enough to warrant a new 20-year patent, for example. By filing patent oppositions, we can highlight this information and the possibility of invalid patents being granted is reduced,” explains Vikas Ahuja, President, Delhi Network of Positive People.
Successful examples include the opposition by Indian groups to GlaxoSmithKline’s patent application in India on the HIV fixed-dose-combination zidovudine/ lamivudine, on the grounds that it was not a ‘new invention’, but simply the combination of two existing drugs. This combination is now widely used in HIV treatment in developing countries. A pre-grant opposition filed by the Cancer Patient Aid Association was also the spur for the rejection of Novartis’s patent application on the salt form of imatinib, on the basis that the medicine was merely a new form of an old medicine. The move – which is now the subject of a challenge before the Supreme Court – opened up generic competition on the drug used in the treatment chronic myeloid leukaemia and brought the price down by 92 per cent from over $2158 per month to $174 per month.
Childs said, “An unwarranted patent not only delays the entry of price-lowering competition, it also undermines the drive for genuine innovation. With very few innovative new drugs in their product pipelines, pharma companies desperately want to stave off generic competition by trying to get more patents on old molecules, or on processes that are not new.”
The Patent Opposition Database aims to guide civil society groups through the process of challenging an unjustified patent. It will allow organisations to forge new alliances and share vital specialist knowledge, as a patent application can often be challenged in different countries on the same basis. It contains a searchable listing of 45 patent oppositions relating to key medicines and over 200 other supporting documents that will aid in the building of future patent oppositions. The resource will grow as more data is added.
The launch of the database marks the 10-year anniversary of the first time a patent opposition filed by a patient group – Thailand’s AIDS Access Foundation – successfully overturned an unfair patent on the HIV drug didanosine in the Thai courts.
