Ajanta Pharma succeeds in revoking Allergan Patents

Ajanta Pharma, a specialty focused pharmaceutical formulation company, has emerged successful in revoking two composition patents of Allergan Inc. The company had applied for revocation of both the patents under independent applications in 2011 on grounds of obviousness, not an invention, not patentable, insufficiency and non-disclosure under Section 8 of the Patents Act (2005) with Intellectual Property Appellate Board (IPAB). The combination patent decision has emerged as a landmark decision at IPAB.

Both the patents were on medicines for eye-related treatments and were granted by the Kolkata Patent Office in December 2007 and May 2008 respectively.

Ajanta Pharma is engaged manufacturing pharmaceutical products. The company runs three divisions -- prescription drugs, OTC and institutional sales.
