A. Patentansprüche

Catchword: 

An amendment to a figure of the patent as granted may extend the protection conferred by the patent even if the claims and the description remain unamended (see point 3 of the Reasons).

Catchword: 

1. On the limits of claim interpretation in the light of the description (see point 13 of the reasons).  2. In application of decision G 3/14, an objection under Article 84 EPC that a claim is not supported by the description is open to examination in opposition or opposition appeal proceedings only when, and then only to the extent that, the lack of support has been introduced by an amendment to the patent. It must thus be accepted that the removal of an inconsistency between the description and a claim amended in opposition or opposition appeal proceedings is not possible when the inconsistency previously existed in the patent as granted (see point 83 of the reasons).

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: 

With regard to the question of compatibility of certain principles of claim interpretation for the purposes of considering novelty or inventive step with Article 69 EPC, reference is made to Reasons 1.1.11 to 1.1.16.  The principle of primacy of the claims seems to exclude the use of the description and drawings for limiting the claims if an interpretation of the claim in the light of common general knowledge already leads to a technically meaningful result. Similarly, the principle, established by case law, according to which "limiting features which are only present in the description and not in the claim cannot be read into a patent claim" is also fully compatible with Article 69 EPC and Article 1 of the Protocol.

Catchword:

Any unclarity that may arise from an ambiguity in an application as filed is to the detriment of a patent proprietor, who is ultimately responsible for the drafting of the application as filed and its claims. The fact that a feature in the application as filed is unclear cannot therefore justify or excuse the complete deletion of the unclear feature or its replacement by another feature if this results in an extension beyond the content of the application as filed. What prompted a patent proprietor to make a particular amendment to the claims cannot have any influence on the outcome of the assessment of the ground for opposition under Article 100(c) EPC (point 8 of the Reasons).

Catchword: 

As to claim construction, see point 2.7 of the Reasons.

Catchword:

Wenngleich sich ein Patentanspruch nicht an einen Linguisten, sondern an die Fachperson richtet, müssen bei der Bestimmung des - stets sprachlich angegebenen - technischen Anspruchsgegenstands aus fachmännischer Perspektive die geltenden Regeln der Sprachlehre ebenfalls berücksichtigt werden (Nr. 4.6 der Gründe).

Catchword: 

Under Article 69(1) EPC the description and the drawings can only be used for interpreting features which are already present in the claims, but not for adding further – positive or negative - claim features or for replacing existing claim features by others (Reasons 2.15). The application as filed usually cannot provide guidance for interpreting the claims of the patent as granted (Reasons 2.16). A board of appeal is not limited to the claim interpretations advanced by the parties but may also adopt a claim interpretation of its own (Reasons 3.4.2). Relying on documentary evidence is not a precondition for the adoption of a certain claim interpretation by a board of appeal (Reasons 3.4.3).

Catchword:

To assess whether an amended patent claim contains added subject-matter under Article 123(2) EPC, the claimed subject-matter must first be determined by interpreting the claim from the perspective of the person skilled in the art. In a second step, it must be assessed whether that subject-matter is disclosed in the application as filed (Reasons 1.3.8 to 1.3.10).

Catchword:

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.

Catchword:

1. If a request is not admitted because earlier objections are not overcome, Rule 111(2) EPC requires that these earlier objections be made explicit in the decision (see reasons 3).

2. Non-convergence of requests is, on its own, not a sufficient reason for non-admittance. It must be reasoned that and why non-convergent requests affect procedural economy in view of the particular circumstances of the case (see reasons 4).

3. The purpose of the claims to define the matter for which protection is sought (Article 84 EPC) imparts requirements on the application as a whole, in addition to the express requirements that the claims be clear, concise and supported by the description. The Board deems it to be an elementary requirement of a patent as a legal title that its extent of protection can be determined precisely. Whether this is the case for a specific patent application (or an amended patent) can only be decided with due consideration of the description. Claims and description do not precisely define the matter for which protection is sought if they contradict each other (see reasons 27 to 34).

Catchword: 

The requirement that the claims are to be supported by the description under Article 84, second sentence, EPC does not necessarily mean that all the "embodiments" of the description of a patent application have to be covered by the (independent) claims, i.e. that all the embodiments must fall within the scope of those claims (see point 6.2.2 of the Reasons).

Exergue : 

Interprétation des revendications de procédé comportant des caractéristiques de type produit (que l'on pourrait qualifier de revendications « process-by-product ») (voir le point 1.1.4 des motifs)

Catchword: 

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. (Reasons, point 5.7)

Catchword: 

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).

Catchword: 

On the application of Rule 80 EPC and the findings of the Enlarged Board of Appeal in G 3/14 in case of an alleged discrepancy between the description and a feature stemming from a granted claim, see point 4.
