- This is the second appeal in this opposition case. In T 303/13, the Board had remitted the case with the "with the order to maintain the patent in amended form on the basis of claims 1 to 5 of auxiliary request 6, filed with the letter dated 26 April 2013, and the description and figures to be adapted" .
- In the decision of the OD, " the cover page, the page bearing the signatures of the opposition division and the "Druckexemplar" appear contain or refer to the claim set dated 7 July 2017", however, " the reasons of the decision as well as an enclosure of the decision refer to the claim set dated 26 April 2013." The wording of these two claim sets differ.
- The decision is therefore insufficiently reasoned. " it is not unambiguously clear from the impugned decision which request it is based on. None of the other parts of the file are of help here."
- The patentee had introduced as sole request in appeal the set of claims of 26 April 2013. The opponent argues that this claims set should not be admitted under Article 12(4) RPBA on the ground that the patentee had failed to submit them before the OD.
- The Board admits the request, because: "The present board is thus bound by the order in decision T 303/13 made by the first board (Article 111(2); T 843/91 of 5 August 1993, Reasons 3.4 citing T 79/89). In T 303/13, the first board ordered the maintenance of the patent based on the claims of what is now the respondent's sole request. Considering the above binding effect, the present board has no discretion to reject as inadmissible the claims of respondent's main request."
