Relaxed guidelines for amendments after grant

The revision is in response to a series of court judgments rendered by the Intellectual Property Court (IP Court), which revoked TIPO’s decisions on not entering the patentees’ claim amendments after grant. According to Article 64 of the Patent Act, amendments to the contents of the specification and drawings after grant should be limited to narrowing the scope of claims, correction of the errors made in the specification, or explanation of obscure descriptions.
