T 1581/08 03-04-2009

1. According to Article 108 EPC a notice of appeal must be filed in writing within two months after the date of notification of the decision appealed from. The notice shall not be deemed to have been filed until after the fee for appeal has been paid.

Under Rule 99(1)(a) EPC, the notice of appeal must contain the name and address of the appellant, under Rule 99(1)(b) EPC an indication of the decision which is impugned, and under Rule 99(1)(c) EPC a request defining the subject of the appeal.

A statement setting out the grounds of appeal must be filed in accordance with Article 108, 3rd sent. EPC and Rule 99(2) EPC within four months after the date of notification of the decision appealed from.

According to Rule 99(2) EPC the statement of grounds of appeal shall indicate the reasons for setting aside the decision impugned, or the extent to which it is to be amended, as well as the facts and evidence on which the appeal is based.

If the extent to which cancellation of the decision is requested is not expressly stated in the notice of appeal, the competent Board has to examine whether the relevant information can be determined from the totality of the appellant's submissions (cf. Case Law of the Boards of Appeal, 5th edition, 2006, VII.D.7.4.1(b)).

If the statement of grounds of appeal is found to lack such reasoning, the appeal is to be rejected as inadmissible (Rule 101(1) EPC).

2. The letter dated 7 August 2008 expressly mentions only the name of the appellant but neither its address nor a statement identifying the decision which is impugned and the extent to which amendment or cancellation of that decision is requested.

However, since the application number of the patent in suit and its publication number are stated, there had been only one opposition filed against that patent, the decision was to reject the opposition and the professional representative acting on behalf of the appellant is identical to the one who filed the notice of opposition and who represented the appellant during the opposition proceedings, the identity of the appellant and the impugned decision can be established by the Board.

As the opposition had been rejected by the Opposition Division with the impugned decision, the Board can also determine from the appellant's submissions that it requests that the decision under appeal be set aside and that the European Patent Nº EP 1 270 498 be revoked.

3. Whereas the letter of 7 August 2008 can be understood to serve as a valid notice of appeal by the appellant, it cannot serve as the statement of grounds of appeal as required by Article 108, 3rd sent. EPC and Rule 99(2) EPC because it lacks the necessary reasoning why the appellant seeks the cancellation of the decision under appeal and the revocation of the patent.

Sufficiency of grounds of appeal is not a question of form, but of substance. The mere existence of some argumentation and carrying the heading "Statement of the Grounds of Appeal" or "Grounds" does not automatically pass the threshold of Article 108 EPC, even if clearly relating to the substance of the impugned decision (cf. T 145/88, OJ EPO 1991, 251, Headnote). On the other hand, sufficiency is also not a question of volume. There is no minimum requirement as to the length or the fullness of detail of the argumentation which is necessary for an admissible appeal. In this context a distinction is to be drawn between insufficiency for the purposes of admissibility and insufficiency as far as the persuasiveness of the grounds is concerned which - if the arguments are not convincing - results in the dismissal of the appeal (cf. T 922/05 not published in OJ EPO, point 2 of the reasons).

According to the established case law of the Boards of Appeal the grounds for appeal should specify the legal or factual reasons on which the case for setting aside the contested decision is based. The arguments must be clearly and concisely presented to enable the Board and the other party or parties to understand immediately why the decision is alleged to be incorrect, and on what facts the appellant bases his arguments, without first having to make investigations of their own (cf. T 220/83, OJ EPO 1986, 249, point 4 of the reasons and Case Law, supra, VII.D.7.5.1).

This principle is also mirrored in Article 12(2) RPBA: "The statement of grounds of appeal ...shall contain a party's complete case. They shall set out clearly and concisely the reasons why it is requested that the decision under appeal be reversed..., and should specify expressly all the facts, arguments and evidence relied on."

Further, to be sufficient for the admissibility of an appeal the grounds must be analysed in detail vis-à-vis the main reasons given for the contested decision (cf. T 213/85, OJ EPO 1987, 482, point 3 of the reasons).

If no or insufficient relationship between the two can be established, the Board considers that the appeal is inadmissible.

4. The case law allowing exceptions to the principles enumerated above (cf. Case Law, supra, VII.D.7.5.2) is not applicable to the present appeal for the reasons that follow.

4.1 It is assumed to the benefit of the appellant that the letter dated 7 August 2008 refers for the grounds of appeal to the numbering of the features a) to k) of claim 1 as stated in point 12 of the decision under appeal, the last phrase: "Exactly the same as that of IRUNDIN, with the same purpose." probably being related to feature l). However, the actual technical features of the patent in suit are not discussed as such. The listing a) to l) could be understood as a rudimentary allegation that the subject-matter of claim 1 of the patent in suit lacks novelty over a document, which is, however, not mentioned.

Even assuming it relates to the ground of opposition of lack of novelty based on document D3, which had been raised by the appellant only with its letter of 2 June 2006, i.e. after the time limit for filing an opposition under Article 99(1) EPC had expired and which was not taken into account by the Opposition Division for this reason, the listing does not involve any legal and/or technical arguments why the features of claim 1 can be clearly and unambiguously derived from document D3.

The appellant alleges that certain features of the pipe of claim 1 are "similar" to the pipe made by itself ("Irundin") but does not define the related content of the Spanish document D3, which is filed without translation into one of the official languages of the EPO, nor does it compare the claimed invention of the patent in suit with the prior art thus defined. The appellant even admits that it does not understand certain features of claim 1 of the patent in suit (features e) and k)) and, when referring to figure 2 of D3, it acknowledges that some features of claim 1 of the patent in suit are not visible (i.e. disclosed) in D3. With this, the appellant leaves it for the Board to not only provide itself a translation of this document in one of the official languages of the EPO, but also to analyse it and to compare the features allegedly disclosed in that document with the features of claim 1 of the patent in suit.

Arguments why the decision under appeal is not correct, thus, are neither clearly and concisely presented by the appellant with its letter of 7 August 2008 in a way to enable the Board and the respondent to understand why the decision of the Opposition Division is wrong, nor is it apparent upon reading the decision of the Opposition Division and the written statements of the appellant for which reasons the decision should be set aside.

4.2 The fact that the appellant in its notice of appeal requested a "deadline to extend time limit and to expand the grounds exhibit more technical" has no effect on this assessment of the admissibility. The request has no legal basis because the time limit for filing the statement of grounds of appeal pursuant to Article 108, 3rd sent. EPC is not extendable, nor is further processing available. Apart from that, the appellant filed no further submissions before issue of the Board's communication regarding the question of the lacking admissibility of the appeal.

4.3 Although this was brought to the appellant's attention by way of this communication, the appellant in its reply dated 6 March 2009 has not submitted persuasive arguments to convince the Board otherwise.

The appellant merely repeats its allegation that the patent in suit would lack inventive step over D1, D2 and figure 3 of D3 without further technical explanation. Apart from the fact that it probably referred to figure 2 of D3 in its letter of 7 August 2008 and now mentions figure 3 for the first time in the opposition and appeal proceedings, the reply contains in essence nothing but the appellant's assertion that the invention of the patent in suit would be obvious "through the reading of an expert". However, it remains a secret what the elements are which the Opposition Division did not consider correctly but which were obvious for an expert on the matter. The fact that the appellant conceded in its letter of 7 August 2008 that it did not understand features e) and k) raises doubts as to the exact qualification of the expert referred to by the appellant.

5. Since the appellant has not filed a sufficient statement setting out the grounds of appeal with which the appellant seeks to have the decision under appeal to be set aside and the patent in suit to be revoked the appeal has to be rejected as inadmissible pursuant to Article 108, 3rd sent. EPC in combination with Rules 99(2) and 101(1) EPC.
