1.14. Amending the description

Catchword: 

1. There is no provision stipulating that examples within the meaning of Rule 42(1)(e) EPC should not be in the form of claim-like clauses, i.e. in the form of one or more independent clauses followed by a number of clauses referring to previous clauses, at the end of or in another part of the description. There is no justification for deleting such examples just because they were drafted as claim-like clauses. They are to be treated like any other part of the description and thus, inter alia, must support the claims (Article 84 EPC). (Reasons 3.4 and 3.5)  2. It is a general and overarching objective, and as such also a "requirement" of the Convention, that authorities, courts and the public interpreting the claims at a later stage should, as far as possible, arrive at the same understanding of the claimed subject-matter as the EPO bodies deciding on the patentability of the same subject-matter. The only tool for achieving this objective is the patent specification as the expression of a unitary legal title. The description, as an integral part of the patent specification, should therefore also serve this overriding objective, i.e. it should provide a common understanding and interpretation of the claims. If the description contains subject-matter which manifestly impedes a common understanding, it is legitimate to insist on its removal under Articles 84 and 94(3) EPC and Rules 42, 48 and 71(1) EPC. (Reasons 5.5.3)  3. The board approves the practice where instead of a direct removal, i.e. the deletion of the subject-matter not covered by the claims, a "removal" by way of an appropriate statement is made, leaving the technical disclosure unaffected. (Reasons 5.7.2)  4. A referral to the Enlarged Board of Appeal whose sole purpose is to correct the Guidelines and which is not necessary either for ensuring a uniform case law within the boards or for the board's decision is not admissible. Such a referral could be perceived as an attempt to encroach on the President's powers under Article 10(2)(a) EPC. (Reasons 8.2.2)

Catchword: 

1. Mere inconsistencies among the indications in the request for grant of a European patent (EPO Form 1001), and between some of them and the originally filed application documents, are not sufficient to prove an alleged obvious error or the obviousness of a correction offered under Rule 139 EPC. 

2. The ban on corrections under Rule 139 EPC by replacement of at least the complete description is categorical.
