The Indian branch of Hoffman-La Roche Scientific has filed two separate petitions against Cipla in the Bombay High Court alleging patent and trademark infringements over its anti-infection drug Valcyte.

The first petition alleges that Cipla Ltd, India’s second largest pharmaceutical company, infringed Roche’s patent by launching a generic version of Valcyte. The second petition says Cipla violated the Swiss drug maker’s trademark by launching the product in a phonetically similar name, Valcept.

Other than that, the companies are not saying much about the development.
