Tuesday, February 12, 2019 T 0592/15 - No postponement of decision

In this examination appeal case, the application as filed comprised three independent method claims (claims 19, 39 and 40). However, after an objection under Rule 43(2) EPC in the European search opinion, all claim sets submitted by the applicant during the examination phase, as well as those filed with the grounds of appeal, contained only one independent method claim.

A month prior to the oral proceedings, the applicant filed a main request and two auxiliary requests, all containing three independent method claims. Four days before the oral proceedings, the applicant informed the Board that he would no attend the oral proceedings. He further advised that "it is intended to file a divisional application based upon the present application and it is requested that the present application be maintained pending until the divisional application has been filed".

The Board found the filing of more than one independent method claim at this stage of the proceedings to be prima facie objectionable under Rule 43(2) EPC. Accordingly, the appellant's main, first and second auxiliary claim requests were not admitted into the proceedings.

As there was no admissible claim request of the appellant, the appeal was to be dismissed. The Board found that the request of the applicant to postpone the taking of this actual decision at least until a divisional application had been filed would require the Board to investigate whether the appellant has eventually indeed filed a divisional application and, as the case may be, to even postpone the oral proceedings. Moreover, the Board found that the appellant would gain complete control over the duration of the present appeal proceedings including the possibility of having them pending ad infinitum if no divisional application was filed at all.

Consequently, the Board refused the appellant's request to postpone the taking of the decision on the allowability of the appeal and decided to dismiss the appeal.

Friday, July 06, 2018 T 0156/15 - Admissibility of expert evidence and tactically filed requests

Does it help to submit an expert opinion regarding added matter in a divisional application (Art. 76(1) EPC), when the expert is a well-known former chair of a technical Board of Appeal and member of the Enlarged Board of Appeal? And how far will the Board go in admitting requests submitted during oral proceedings in response to the Board’s deliberations on previous requests?

European patent No. 2 106 790, based on European patent application No. 09007867.6, was filed as a divisional application of European patent application No. 05728268.3. Opposition to the patent was filed by one opponent. By interlocutory decision of the Opposition Division, the patent in suit was maintained in amended form according to Auxiliary Request 1. This Auxiliary Request 1 only differed from the patent as granted in an amendment introduced in paragraph [0020] of the description. Claim 1 of auxiliary request 1 was identical to claim 1 of the patent as granted, which reads:

"1. A composition, which has been prepared in a solution, comprising a therapeutically effective dose of insulin or insulin derivative, ions of citric acid, and a zinc metal chelator effective to dissociate the insulin into monomers or dimers, in a form suitable for subcutaneous administration".

The amendment to paragraph [0020] of the description resulted in citric acid no longer being listed as a suitable chelator, but only as a solubilising acid, thus arguably rendering the claim novel over prior art document D2.

Both parties appealed the decision. The opponent argued, inter alia, that the patent was not in compliance with Art. 76(1) EPC, as the parent patent nowhere disclosed “ions of” of any acid as solubilising agent.

During oral proceedings, the Board came to the conclusion that by admitting submissions made by a former Board member, however eminent that person might be, it would attach undue weight to the individual making the argument rather than focus on the argument itself. Accordingly, the expert opinion was not admitted into the proceedings – rather, the Board allowed the proprietor to rely on the arguments presented therein merely as his own submissions.

Regardless, the Board found that the Main Request – identical to claim 1 as granted - does not comply with the requirements of Article 76(1) EPC, since it cannot be directly and unambiguously derived from the earlier application that the compositions of claim 1 inevitably contain the ionic form of the acids. Auxiliary requests filed sequentially in response the Board’s deliberation in this matter and on the admissibility of the requests itself were not admitted for lack of prima facie relevance or raising new issues. The Board further stressed that by adjusting its strategy to the results of the Board's deliberation, the proprietor puts the opponent in a position where it is difficult to react. For this reason, in principle, the Board could have refused these requests even without also considering the specific criteria for the exercise of its discretion to admit new auxiliary requests.

The only remaining request not violating Art. 76(1) EPC – i.e., relating to compositions containing an acid in its non-dissociated (no ions) form – then led to an inescapable trap (Art. 123(3) EPC) situation, and the patent was revoked.

Friday, July 21, 2017 J 13/14 - On divisionals and translations...

Translating prohibited?

The present European patent application was filed in English as a divisional application from a parent application which was as an international application filed in German and also published in German. On entry of the parent application before the EPO, a translation into English was filed.

However, filing the divisional application in English turned out to be fatal mistake. 

According to Rule 36(2), a divisional application shall be filed in the language of the proceedings for the earlier application, while providing for an exception in case the latter was not filed in an official language of the European Patent Office, in which case the divisional application may be filed in the (non-official) language of the earlier application while having to provide a translation.

Filing the English translation did not change the language of proceedings of the parent application (which remained German). German is an official language of the EPO, so the exception of Rule 36(2) does not appear to apply. However, one cannot fault the appellant for exploring all legal remedies.

Catchwords: 

1. For the purposes of Article 76(1), first sentence, and Rule 36(2), first sentence, EPC, a European divisional application of an earlier European patent application which was filed in an EPO official language must also be filed in the EPO official language of the earlier application. Otherwise, it is filed in an inadmissible language. In this case a correction of the language deficiency by means of a translation into the language of the proceedings for the earlier application is neither required under Rule 36(2), second sentence, EPC nor is it even admissible in view of the wording of that provision and the Enlarged Board's decision G 4/08. Nor is it possible for the applicant to remedy the language deficiency in its divisional application by means of a correction under Rule 139, first sentence, EPC or by means of an amendment under Article 123(2) EPC.

2. In accordance with the established jurisprudence of the boards of appeal, a European divisional application which was filed in an inadmissible language cannot be treated as a valid divisional application by analogous application of Article 90(2) EPC.

Friday, January 15, 2016 T 108/12 A divisional application in the inescapable trap

The application of this appeal procedure is a divisional application. The Opponent argued during the Opposition procedure and during the Appeal Procedure that the divisional application extends beyond the disclosure of the mother application. This case shows once again that one has to be careful in changing something in the divisional application. The details of this case are a little bit mathermatical and the reasoning of the Board is strongly based on what would the skilled person in the field of security/encryption consider to be the teaching of the original application. One point of discussion is: Does the mother application provide enough support for  f(α)=f'(α) (as claimed in the divisional application), if the mother application teaches f(α)=f'(α)=α? Another point of discussion was: Does the mother application provide enough support for "a specific signature is kept private" (as claimed in the divisional application) while the mother application discloses that, in certain embodiments, the signature is not transmitted.
Ok, there were problems with support of the divisional application in the mother application, but the proprietor finally ends up in the inescapable trap. It is somehow sad to end up in the inescapable trap.
