Tuesday, July 17, 2018 T 181/17 - Inventive step attack with document used for novelty attacks as closest prior art

The introduction of new grounds during opposition and opposition appeal proceedings may be difficult, but also the introduction of new lines of reasoning in support of raised grounds of opposition. A raised ground of lack of inventive step may allow assessment of novelty in view of  the closest prior art - G 7/91 and Guidelines (2017) D-III, 5. Also, in a case where a patent has been opposed under Article 100(a) EPC on the grounds of lack of novelty and inventive step having regard to a prior art document, and the ground of lack of novelty has been substantiated, a specific substantiation of the ground of lack of inventive step is neither necessary - given that novelty is a prerequisite for determining whether an invention involves an inventive step and such prerequisite is allegedly not satisfied - nor generally possible without contradicting the reasoning presented in support of lack of novelty; in such a case, the objection of lack of inventive step is not a fresh ground for opposition and can consequently be examined in the appeal proceedings without the agreement of the patentee - T 131/01. One would expect that introducing a new line of attack for an existing ground to be less difficult, e.g. when introducing a new inventive step attack using a document used for novelty as closest porior art. However, in the case below, the inventive step attack based on D17 -not admitted in first instance proceedings, but filed with and admitted into the appeal and used for several novelty attacks- as the closest prior art was not admitted into the proceedings in accordance with Article 13(1) Rules of Procedure of the Boards of Appeal (which provides that any amendment to a party's case after it has filed its grounds of appeal or reply may be admitted and considered at the Board's discretion, where the discretion shall be exercised in view of inter alia the complexity of the new subject-matter submitted, the current state of the proceedings and the need for procedural economy.)

Tuesday, September 15, 2015 T 169/12 - late lines of attack

In appeal against the rejection of the opposition, the opponent submitted new lines of attacked based on documents that were originally mentioned in the notice of opposition, but were never used in any attack before the opposition division. The appellant (opponent) further submitted two new documents in the appeal procedure. Which of the documents and which lines of attack were admitted into the procedure in view of Art. 12 and 13 RPBA?
