T 17/22 - On the "Invitation pursuant to Rule 137(4) EPC and Article 94(3) EPC"
In the present case, the examining division issued a decision to refuse the application based on the ground under Article 123(2) EPC and on lack of novelty, lack of inventive step and lack of clarity. However, the examining division had issued only two communications before deciding to refuse the application: the first was a communication under Rules 161(1) and 162 EPC, inviting the applicant to correct any deficiencies noted in the written opinion raised by the EPO as ISA in the international phase, and the second was a communication under Rule 137(4) EPC headed "Invitation pursuant to Rule 137(4) and Article 94(3) EPC", accompanied by an annex raising an objection under Article 123(2) EPC and the statement: "nota bene: The amendment appears also not suitable to remedy the deficiencies". In the statement setting out the grounds of appeal, "the appellant contended among others that the examining division had committed a substantial procedural violation as, in the proceedings before the examining division, the appellant never had the opportunity to address the objections as expressed in the appealed decision. Moreover, with the invitation pursuant to Rule 137(4) EPC, the appellant had only been alerted that certain amendments had not been sufficiently identified and/or their basis in the application as filed has not been sufficiently indicated. The subsequent decision to refuse the European patent application without any further ado had come completely to the surprise of the appellant. Thus, the appellant submitted that the right to be heard under Article 113(1) EPC had been violated.".
The Board considered the scope of Art. 94(3) EPC in detail and considered that at least one substantive communication pursuant to Art. 94(3) EPC and Rule 71(1) EPC is required before a decision to refuse the application on substantive grounds is issued (or, exceptionally, summons for OP). The Board addressed in detail whether a communication under Rules 161(1) and 162 EPC can/cannot be considered a communication under Article 94(3) EPC and whether an "Invitation pursuant to Rule 137(4) EPC and Article 94(3) EPC" can/cannot considered a substantive communication under Article 94(3) EPC.
