Updating our previous post concerning the patent status of the antiretroviral Raltegravir in India, we can confirm that application no. 868/CHENP/2004 has now been granted in the Official Journal of 15 February 2008. The granted Patent No. is 212400. See also the post by Patent Circle here.
Following Maraviroc and Etravirine, which was recently granted a patent in India, Raltegravir is third next- generation antiretroviral to have been granted a patent in India.
Any interested parties seeking to file a post-grant opposition against Raltegravir will have until 14 February 2009 to do so.
