Gilead files patent suit against Teva

22 December 2008

Gilead Sciences has filed a law suit in the US District Court in New York against Teva Pharmaceuticals USA and Israeli parent Teva Pharmaceutical Industries for infringement of US patent numbers 6,642,245 and 6,703,396. Both are associated with emtricitabine, a component of Truvada (emtricitabine and tenofovir disoproxil fumarate), and are licensed exclusively to Gilead Sciences by Atlanta-based Emory University. Truvada is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults.

The law suit is based on an Abbreviated New Drug Application filed by Teva Pharmaceuticals USA, which seeks approval to manufacture and market a generic version of Truvada before the expiration of both emtricitabine patents.
