5. Stützung durch die Beschreibung

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:

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).

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.

Zusammenfassung

In T 56/21 the board addressed the question whether Art. 84 EPC provides a legal basis for (i) objecting to an inconsistency between what is disclosed as the invention in the description (and/or drawings, if any) and the subject-matter of the claims, the inconsistency being that the description (or any drawing) contains subject-matter which is not claimed, and (ii) requiring removal of this inconsistency by way of amendment of the description (hereinafter: "adaptation of the description").

As the appeal concerned ex parte proceedings, the board dealt with the interpretation of Art. 84 EPC for the purpose of its application in examination proceedings. The board analysed the function and relationship of the claims and the description, the relationship between the assessment of patentability and the determination of the extent of protection as well as the requirements of support by the description and clarity in Art. 84 EPC.

On adaptation of the description, the board came to the following conclusions:

(a) Art. 84 and R. 43 EPC set forth requirements for the claims, not for the description.

(b) It is the purpose of the assessment of Art. 84 EPC as part of the examination of patentability to arrive at a definition of the patentable subject-matter in terms of distinctive technical features distinguishing it from the prior art.

(c) Art. 69(1) EPC and the Protocol on the Interpretation of Art. 69 EPC are not concerned with the definition of the subject-matter according to Art. 84, first sentence, EPC, or the assessment of patentability in examination before the EPO but with the extent of protection in the context of infringement proceedings in the contracting states. Art. 69 EPC and its Protocol are hence not applicable in grant proceedings before the EPO.

(d) The requirements of Art. 84 EPC and R. 43 EPC are to be assessed separately and independently of considerations of extent of protection when examining a patent application.

(e) In examination, future legal certainty is best served by a strict definitional approach which ensures that allowable claims per se provide an unambiguous definition of the subject-matter meeting the requirements for patentability.

(f) Adapting the description to match the more limited subject-matter claimed does not improve legal certainty but reduces the reservoir of technical information in the granted patent. This may have unwarranted consequences in post-grant proceedings and may encroach on the competence of national courts and legislators.

(g) R. 48 EPC is not concerned with the adaptation of the description, but with the avoidance of expressions which are contrary to public morality or public order, or certain disparaging or irrelevant statements in the publication of an application.

The board held that in examination of a patent application, neither Art. 84 nor R. 42, 43 and 48 EPC provide a legal basis for requiring that the description be adapted to match allowable claims of more limited subject-matter. Within the limits of Art. 123 EPC, an applicant may, however, amend the description of its own volition.

In the case at hand the description included a passage entitled "SPECIFIC EMBODIMENTS", which contained claim-like clauses. Those clauses included subject-matter which was not claimed. The board set aside the (refusal) decision under appeal and the case was remitted to the examining division with the order to grant a patent based on the main request on file.
