May a patent application be amended during examination, and what is the key limitation?
Yes, an applicant may amend the application during examination, but with an important restriction. Section 49, Intellectual Property Code of the Philippines, allows amendment provided that such amendment does not include new matter outside the scope of the disclosure contained in the application as filed. This means the applicant cannot use amendment to add totally new technical subject matter that was not originally disclosed. Amendments must stay within the bounds of the original disclosure while clarifying or refining the claims or description. 21-Dec-25About Nicolas and De Vega Law Offices
