Dispute Summary
Novartis AG applied for a patent on the ß-crystal form of imatinib mesylate. Hetero Drugs Limited opposed the application, arguing that the invention was anticipated by prior art and did not meet the enhanced efficacy criteria under Section 3(d) of the Patents Act, 1970. The Tribunal agreed with the opposition, finding that the subject matter was a new form of a known substance without significant improvement in efficacy.
