Feedback to IPOS on 18 December 2025 Regarding the Use of Invitations to Amend for PPH Requests
ASPA sent an email to the Intellectual Property Office of Singapore (IPOS) on 18 December 2025 enclosing a letter titled “Letter from ASPA to IPOS - Use of Invitations to Amend for Patent Prosecution Highway Requests Made After a Request for Examination Has Been Made”.
The letter concerned the use of Invitations to Amend for Patent Prosecution Highway requests made after a request for examination has already been made.
IPOS responded on 3 March 2026 to acknowledge ASPA’s views. IPOS also indicated that it would propose amendments to the Examination Guidelines for more clarity.
