Guidelines for Examination


4.2 Allowability of corrections

Correction of errors is a special form of amendment, and the requirements of Art. 123(2) therefore apply mutatis mutandis.

If a request for correction does not comply with Rule 139, and the applicant or patent proprietor maintains the request, the proposed change in the text is to be treated as an amendment and must comply with Art. 123(2) and, where applicable, Art. 123(3).
