5.1.7 Applicability of Rule 137(5) EPC in opposition proceedings

You are viewing the 9th edition (2019) of this publication; for the 10th edition (2022) see here

The board in T 735/12 held that an opponent's objection under R. 137(5) EPC that a claim included features taken only from the description and therefore unsearched was inoperative if only because R. 137 EPC governed solely amendments to a European patent application and was therefore not applicable in opposition (appeal) proceedings.
