T 0127/85 (Blasting compositions) of 01.02.1988

Objections to clarity of claims or any consequent requests for amendment are only relevant to opposition proceedings as far as they can influence the decisions on issues under Art. 100 EPC or arise in relation to matter to be amended in consequence of such issues (cf. point 2.1 of the Reasons).

It could lead to an abuse of the opposition proceedings if the patentee were allowed merely to tidy up and improve his disclosure by amendments (here: deletion of an example) not necessitated by proper opposition grounds (cf. point 7.1 of the Reasons).
