Dispute Summary
Daewoong Pharmaceutical appealed the rejection of its Indian Patent Application (No.201817048074), which covered a crystalline form of compound c28. The rejection was based on Section 3(d) of the Patents Act, 1970, as the drug was considered known and lacked enhanced therapeutic efficacy. Daewoong sought to introduce additional data demonstrating superior properties like stability and dissolution rates. The High Court accepted the application for additional documents but framed two critical issues: whether this post-filing data is admissible, and if the crystalline form ultimately meets Section 3(d) requirements.
