Tuesday, May 11, 2021 T 2255/15 - Can the Board of Appeal disregard third party observations that were only filed during the appeal proceedings?

In the present case, the appeals lodged by the opponent and the patent proprietor lie from the interlocutory decision of the opposition division that the European patent No 1 369 037 in amended form. Third party observations were submitted in an early stage of the appeal proceedings, as well as in later stages, objecting to novelty and to inventive step w.r.t. newly field documents (existing grounds, but new facts, arguments and evidence). The patent proprietor requested that the third-party observations, with all the documents and annexes referred to in the observations, not be admitted into the proceedings as they were late-filed. However, the RPBA seems to only impose constraints on late-file submissions by parties, as does Art. 114(2) EPC, and not by third parties. How did the Board handle these third party observations: were they admitted and, if so, to what extent?

Tuesday, February 02, 2021 T 1370/15 - A board is allowed to introduce common general knowledge without evidence also in inter partes

The use of grids is well known in the art

After his patent was revoked in opposition, the proprietor filed an appeal. The opponent (respondent) did not make any submissions in response to the appeal. The board was not convinced that the appellant's requests were inventive taking the common general knowledge of the person skilled in the art into account. In particular, the common general knowledge should not be restricted to the material presented in the first-instance proceedings or the oral proceedings by the appellant. 

The board provided the following catchword:

Not only in ex parte-, but also in inter partes appeal proceedings, a board is allowed to introduce new ex officio common general knowledge without evidence of such knowledge which prejudices maintenance of the patent, to the extent that the board is knowledgeable in the respective technical field from the experience of its members working on cases in this field. (See Reasons, point 5.3)

(emphasis added)

Tuesday, November 26, 2019 T 341/15 - Late documents and late requests in first and second instance

In the present case, the Opposition Division admitted into the proceedings late-filed documents D9 and D14 and held that claim 1 of the then main request (patent as granted) and of the then first to sixth auxiliary requests did not involve inventive step pursuant to Article 56 EPC starting from D9 as closest prior art in combination with the teaching of D14. The appellant (proprietor) holds the view that they should not have been admitted into the proceedings similarly to other documents which had not been admitted by the Opposition Division. At the oral proceedings before the Board the appellant further added that D9 only concerns the preamble of claim 1 of the main request so that it would not be relevant to the invention. The Board discussed that, according to the established case law a Board of appeal should only overrule the way in which a department of first instance has exercised its discretion if it concludes that it has done so according to the wrong principles, or without taking into account the right principles, or in an unreasonable way, and has thus exceeded the proper limits of its discretion. When considering their admission into the proceedings, the Opposition Division applied the correct criterion of prima facie relevance. In this respect the Board follows the respondent's (opponent's) view that there is no legal basis or available case law according to which some circumstances would justify that only novelty, i.e. not inventive step, should be considered for the criterion of prima facie relevance.

Tuesday, September 24, 2019 T 1359/14 (and T 1914/12) - Does the Board have discretion to admit late arguments based on facts already in the proceedings?

A reader pointed me to this decision, in French. In reason 2.1, the Board indicates that a Board has no discretion as to the admissibility of late arguments based on facts already in the proceedings. The Board referred to and followed pararaph 7.2.3 of T 1914/12, also in French, which substantially decided that the lack of "arguments" in Art. 114(2) EPC allowed to file new arguments late, contrary to what Art. 12 RBPA said/says. In view of the tightening of what will be allowed and not with the revised RPBA that enters into force on 01.01.2020, it wil be interested whether a future Board will come to the same conclusion.

In any case, it appears that there should be a referral as this decision follows T 1914/12 which however distinguished from T 1621/09, and seems is a fundamental point of law.

Thursday, September 20, 2018 T 1914/12 - Does the Board have discretion as to the admissibility of late arguments based on facts already in the proceedings?

A decision in French, but well worth reading (and well-readable, too). It concerns the question whether the Boards of Appeal, based on Articles 12(2) and 13(1) of the Rules of Procedure of the Boards of Appeal (RPBA), have the discretion not to admit arguments submitted late in the proceedings - when the facts (in this case, a prior art document) underlying these arguments have been filed in time. It particularly deals with the legal meaning of the terms "facts" and "arguments", and how "facts, evidence or requests" (Art. 12(4) RPBA) and "amendments (to a party's case)" (Art. 13 RPBA) relate to Art. 114(2) EPC, stipulating that the European Patent Office may disregard "facts or evidence" (but not arguments?) not filed in time.

The present appeal lies from the decision of the Opposition Division to revoke European Patent EP1968779 on the grounds of lack of novelty and inventive step in view of, among others, prior art document D51. Briefly, the patent is concerned with a method for bonding a strip of a flexible sheet to a rigid support involving a step of pressing and heating a polymerizable adhesive applied between the support and the strip.

In its grounds of appeal, the proprietor provided several arguments as to why the subject matter of claim 1 distinguishes itself from the disclosure of D51. In a subsequent written submission - filed after transfer of the patent from the original proprietor to the original opponent - the new proprietor argued that, in addition to the distinguishing features discussed previously, D51 differs from claim 1 by disclosing a thermoplastic rather than a polymerizable adhesive (the latter point having merely been noted in the grounds, but not elaborated on).

In its preliminary opinion preceding Oral Proceedings, the Board expressed its intention not to accept the late argument that the nature of the adhesive used was an additional distinguishing feature.

During Oral Proceedings, the proprietor submitted that the assessment of a late argument must be applied according to a more flexible test than facts, evidence or requests, according to the RPBA interpreted in the light of its travaux préparatoires, in which the explicit inclusion of the term "arguments" had been debated. The proprietor further held that the belated argument is a pure argument concerning the underlying technical reality, namely the nature of the adhesive used. In this case, it is not the facts of the case that have changed, but the position of the parties on the interpretation of a document. In regard of Art. 114 EPC, the expression "in due time" must be interpreted in respect of the right of the parties to a fair trial and the duty of the Board to judge whether a fact corresponds to the technical reality.

In its reasons, the Board concluded that indeed a "fact" can be understood as a factual (or allegedly such) element or a circumstance on which a party bases its claims, whereas an "argument" would mean a proposition that a party bases on one or more facts and that supports the plea ["moyen" in the decision] which the party debates.

The Board further noted that in the "Proposal to amend the Rules of Procedure of the Boards of Appeal (RPBA)" of 2002, leading to the current version of the RPBA, "arguments" had initially been included in the definition of "amendments to a party's case". According to the Board, the deletion of the words "arguments" from the final (current) version seems to express the intention of the Praesidium, after consultation with the Patent Law Committee, to exclude arguments from the discretionary power conferred to the Boards of Appeal.

The Board cited T 1794/12 of 16 January 2018, which relied on point 3.1 of the article by B. Günzel, "The treatment of late submissions in proceedings before the boards of appeal of the European Patent Office" ( OJ EPO, Special Edition 2/2007, page 30):

For one thing, submissions can only be rejected on the grounds of being late if the decision-making body would not have been required to examine them and take them into consideration of its own motion. It is incumbent on every decision-maker and thus also on the boards of appeal to weigh up all the relevant legal and technical arguments in making their decision. Such arguments must therefore, at least when they involve the facts of the case and not new grounds for opposition, be taken into account at all stages of the proceedings, including the appeal stage, and cannot be rejected on the grounds of being late.

As regards previous Board decisions, the present Board is not persuaded by the reasoning behind T 1069/08 and T 1621/09 - followed by many Boards - which rely exclusively on the application of Article 13(1) RPBA from the formulation of Article 12(2) RPBA to recognize the discretion of Boards in (not) admitting late submissions. According to this Board, the interpretation of those decisions ignores the fact that Article 114(2) EPC does not justify such discretion, as previous case law has repeatedly stated. According to the Board, the EPC, and in particular its Article 114 - at least in its English version - raises a difference in the treatment of facts and arguments. In particular, Article 114(2) EPC provides for a discretionary power with regard to the facts invoked belatedly, and not for late arguments based on facts already in the proceedings. Even when drafting the RPBA, the legislator seems to have intended to maintain this distinction, as is apparent from the preparatory work on Article 13 RPBA. According to this board, the RPBA, also in view of Art. 23 thereof, although it can specify and interpret the provisions of the EPC, it cannot confer on the Boards of appeal powers which the EPC does not give them.

Thus, departing from T 1621/09, the Board found that the Boards of Appeal do not have a discretion as to the (non)admissibility of late arguments based on facts already in the proceedings.

Consequently, the proprietor's assertion concerning the nature of the adhesive used, first presented in its letter of 15 October 2015, constitutes a new argument in support of the plea which it defends, namely: that the subject matter of claim 1 is novel compared to document D51. Taking into account of this argument necessarily leads to the consideration of the applicant's argumentation concerning the inventive step of the subject-matter of claim 1. The Board comes to the conclusion that it has no discretion as to the (non)admission of these arguments. It follows that the additional difference must be taken into consideration.

With this new distinctive feature, a new line of argument has been submitted for consideration of inventive step. In view of the fact that this distinctive new characteristic may have an influence on the choice of the closest prior art, a referral of the case in the first instance is considered justified by the Board.

Tuesday, November 29, 2016 T 628/14 - Within time limit for making written submissions, but too late

In this opposition appeal, an opponent submitted new documents in response of the invitation to oral proceedings under Rule 116(1) EPC ("When issuing the summons, the European Patent Office shall draw attention to the points which in its opinion need to be discussed for the purposes of the decision to be taken. At the same time a final date for making written submissions in preparation for the oral proceedings shall be fixed. Rule 132 shall not apply. New facts and evidence presented after that date need not be considered, unless admitted on the grounds that the subject of the proceedings has changed."). The documents were not admitted in the proceedings as they were late filed and prima facie not relevant. The Board emphasized that the invitation for written submissions should, according to established case law, not be construed as an invitation to file new evidence or other material departing from the legal and factual framework of issues and grounds pleaded as established with the notice of opposition. The Board also reviewed that it is at the first-instance division's discretion to admit late filed documents or not, and concluded that the first instance division did not exercise its discretion in an unreasonable way as it had assessed the prima facie relevance of both documents.

Thursday, October 06, 2016 T 971/11 - Too late for first instance but admissible in appeal

After you missed the first train, can you catch the next?

The opponent filed a document B1 just before the first-instance oral proceedings. The opposition division considered the document late and not prima-facie relevant. The document was not admitted into the proceedings. The document is again submitted with the statement of the grounds. 

On the one hand the appeal board should only verify that the opposition division's decision not to admit the document was not unreasonable. On the other hand, they need to make up their own mind when the document is presented with the appeal? The board discusses this dilemma, and in the end does not hold it against B1 that is was already rejected by the opposition division. B1 is admitted into the appeal procedure. Another new document that was filed just before the oral proceedings in appeal was not admitted.

Friday, May 15, 2015 T 1756/11 - Third party excluded from the party?

This is an appeal against a decision of the Opposition Division to maintain European Patent No. 1 219 158 in amended form in accordance with the proprietor's first auxiliary request.

The opponent filed its notice of appeal on 9. August 2011 while paying the appeal fee. The grounds were filed on 23. September 2011.

Observations by third parties were filed on 17. January 2013 and, in accordance with Art. 114 (2) EPC, communicated by the Board towards the parties.

The preliminary opinion of the Board was issued on 30. September 2014. Oral proceedings took place on 14. January 2015.

Neither the Appellant or respondent commented on the Observations by third parties.

The Board in this decision decides to disregard the late-filed third party observations and to refrain from mentioning them in its decision. Cited below is the board's motivation for this.

Headnote

"See Reasons 2"

Briefly paraphrased and translated as:

Reason 2.3: Art. 114(2) gives the Opposition Division the right to disregard late-filed facts or evidence. However, this applies to filings by parties to the proceedings, which according to Art. 115 a third party is not. Nevertheless, Art. 114(2) is considered to still apply to third party observations which were filed after the opposition time limit by way of a legal fiction according to T 951/91, reason 5.9.

The reasoning behind this is to prevent Art. 115 being (ab)used to expand the rights of third parties or even parties to the proceedings.

Reason 2.5: Although a third party thus has no right to have its observations considered by the Opposition Division, it is common practice for the Opposition Division to at least comment on the relevance of such late-filed third party observations in their decision.

Reason 2.6: Due to the third party not being a party to the proceedings, there is thus no need to, in case of late-filed third party observations (i.e., filed after the time limit for filing the notice of opposition), to comment on their inadmissibility in case the Opposition Division considered the observations not relevant and further disregarded them.

Reason 2.7: On the other hand, the Opposition Division may nevertheless consider and examine such late-filed observations out of its own motion under Art. 114(1) if it considers them prima facie relevant.

Reason 2.8: However, in appeal proceedings, the own-motion principle applies to a lesser degree ("verliert (...) das Gewicht"), especially in inter-partes proceedings, G 9/91, G10/91, reason 18. Here, the impartiality of the Board of Appeal is of up-most importance.

Reason 2.9: The Board of Appeal thus generally needs to disregard late-filed third party observations, except when they relate to amendments during the opposition or appeal-proceedings, G 9/91, G10/91, reason 19, in which case the Board may or may not admit them into the proceedings.

Reason 2.10: A party to the proceedings may however at all times submit comments on new facts or evidence from such third party observations, when these in their view can affect the decision. This right comes forth from Art. 113(1), i.e., the right to be heard. In this case, the Board has to decide on the (in)admissibility of such late-filed comments from the party to the proceedings.

Reason 2.11: In the present case, despite there being claim amendments during the opposition proceedings, the Board is of the opinion that the (anonymous) late-filed third party observations are to be disregarded and not mentioned in the decision. No party commented on the observations either in accordance with reason 2.10.

Tuesday, May 05, 2015 T 2541/11 - "Right to be heard not absolute, but must be balanced"

The appellant-opponent lodged an appeal against the interlocutory decision of the opposition division  on the amended form in which European patent no. 1394387 could be maintained. The appellant-proprietor also lodged an appeal against the above interlocutory decision. The appellant-opponent filed a new document, E12, with their grounds of appeal. The Board did not admit this new document.

Background / Summary of Facts and Submissions

I. The appellant-opponent lodged an appeal, received 12 December 2011, against the interlocutory decision of the opposition division posted on 13 October 2011 on the amended form in which European patent no. 1394387 could be maintained and paid the appeal fee simultaneously. The statement setting out the grounds of appeal was filed on 23 February 2012.

The appellant-proprietor also lodged an appeal, received 14 December 2011 against the above interlocutory decision and paid the appeal fee simultaneously. The statement setting out the grounds of appeal was filed on 20 February 2012.

II. The opposition was filed against the patent as a whole and based inter alia on Article 100(a) together with Articles 52(1) and 54(3) EPC for lack of novelty and Article 56 EPC for lack of inventive step.

The division held, inter alia, that the grounds for opposition (novelty and inventive step) mentioned in Article 100(a) EPC did not prejudice maintenance of the patent as amended according to an auxiliary request, having regard to the following documents, amongst others: E1, E4, E6, E9.

III. The appellant-opponent filed the following document with their grounds of appeal: E12.

IV. Oral proceedings before the Board were duly held on 17 December 2014. During the oral proceedings, the appellant-opponent filed an objection under Rule 106 EPC in writing. It reads as follows:

Objection acc. to Rule 106 EPC; in the name of the opponent.

The decision to not admit reference E12 into the proceedings constitutes a violation against the right to be heard for the following reasons:
