Les procédures d’opposition contre les brevets de Myriad Genetics sur le gène BRCA1 ont débouché sur la révocation totale d’un premier brevet sur la méthode de diagnostic génétique du cancer du sein, décision de l’Office européen des brevets (OEB) du 18 mai 2004, puis sur la révocation de l’essentiel du second brevet qui portait sur le gène lui-même, le 21 janvier 2005. Ce brevet ne porte plus que sur quelques fragments du gène utilisés comme sondes, les revendications sur les applications diagnostiques ayant été supprimées. Enfin, le 25 janvier 2005, L’OEB a fortement réduit les revendications d’un troisième brevet qui portait sur des mutations particulières du gène. Au lieu des 34 mutations accordées initialement par l’OEB, ce brevet ne porte plus que sur une sonde étroitement définie pour détecter une seule mutation. Et l’usage de cette sonde n’est pas un point de passage obligé. Ces décisions mettent fin au monopole juridique revendiqué par Myriad Genetics sur le gène BRCA1 dans sa totalité et sur le diagnostic génétique du cancer du sein. Elles laissent le champ libre aux généticiens européens qui peuvent développer et mettre en oeuvre leurs méthodes de tests dans le cadre d’une organisation clinique et à caractère non lucratif1.
Abstract
proceedings instituted against three European patents held by the US company Myriad Genetics, on the BRCA1 gene and the breast cancer diagnosis gene, resulted in the total or partial revocation of these patents. These decisions put an end to the legal monopoly claimed by Myriad Genetics on the BRCA1 gene and on breast cancer gene tests, and left the field open to European geneticists to develop and implement theirtest methods within the framework of a clinical not-for-profit organization. The opposition procedure, through which any actor is allowed to challenge European patents, was used by geneticists doctors in Europe to refuse the emergence of an industrial monopoly on a medical service offered in a clinical context. The decision to revoke or strongly limit these patents was based on the European Patent Office’s refusal to establish an invention priority on a sequence that had errors at the time the application was filed by the patent holder, in September 1994. The patent holder was granted an invention priority only on 24 March 1995, when it filed an application for a corrected sequence of the gene. But by then the BRCA1 gene sequence had already been divulged in a public data base, Genbank, from October 1994, notably by Myriad. Myriad Genetics’ patents were thus victims of the patent race that prompted the firm to file multiple patent applications on insufficiently validated sequences, and of the conflict between diffusion in the public domain and the novelty requirement. Opposition to the patents, undertaken by a coalition of medical institutions, human genetic societies, two States, Holland and Austria, an environmental protection organization (Greenpeace), and the Swiss Labour Party, made it possible to preserve and develop the clinical economy of genetic tests in Europe. It resulted in amendments to intellectual property laws in France and thus extended the possibility of using compulsory licences for public health purposes to in vitro diagnosis.
