Singapore patent office denial of post grant amendments in revocation hearing founded on undue delay and unfair advantage

Last month, the Intellectual Property Office of Singapore (IPOS) Patent Registrar invoked its discretionary powers to deny a patentee’s request to enter post grant amendments as a defense in a revocation hearing based on findings of undue delay in presenting the post grant amendments and unfair advantage in pursuing monetization efforts in Singapore centered on the broader unamended Singapore claims when narrowing amendments had been required to obtain or retain grant of corresponding patents in other countries.
