1. The provisions in Article 84 EPC and Rules 42 and 43 EPC provide an adequate legal basis for claim interpretation when assessing patentability. In particular, the requirement that the claims shall be "supported by the description" in Article 84 EPC, 2nd sentence, indicates that the description may be relied upon as an aid or support for understanding the subject-matter of the claims. 2. However, as implicitly derivable from this provision, the support of the description for interpreting the claims should only be resorted to in the exceptional cases where the subject-matter of the invention and/or its technical context needs to be clarified, and may only be applicable when the invention in the description corresponds to the invention as claimed. 3. The support of the description should, in any case, not be used for restricting or modifying the subject-matter of the invention beyond what a person skilled in the art would understand when reading the wording of the claims within the relevant technical context.

The normal rule of claim construction of reading a feature specified in a claim in its broadest technically meaningful sense corresponds to determining the broadest scope encompassed by the subject-matter being claimed according to a technically sensible reading. In the case of a feature defined in a positive manner, which imposes the presence of a specific element, this is effectively achieved by giving to the element in question its broadest technically sensible meaning. However, for a feature defined in a negative manner, which excludes the presence of a specific element, the broadest scope of the claim corresponds to the narrowest (i.e. most limited) technically sensible definition of the element to be excluded.

1.) Article 69 EPC in conjunction with Article 1 of the Protocol thereto can and should be relied on when interpreting claims and determining the claimed subject-matter in proceedings before the EPO, including for the purpose of assessing compliance with Article 123(2) EPC (Reasons 3.1-3.15). 2.) Although Article 69(1), second sentence, EPC requires that generally account be taken of the description and the drawings when interpreting a claim, the primacy of the claims according to Article 69(1), first sentence, EPC limits the extent to which the meaning of a certain claim feature may be affected by the description and the drawings (Reasons 3.16-3.16.2). 3.) Claim interpretation is overall a question of law which must as such ultimately be answered by the deciding body, and not by linguistic or technical experts. It does, however, involve the appraisal of linguistic and technical facts which may be supported by evidence submitted by the parties (Reasons 3.17).
