Key points
- "At the end of the oral proceedings, the examining division informed the appellant that it could expect a communication pursuant to Rule 71(3) EPC on the basis of auxiliary request 2, provided that a clean copy of the application documents was filed."
- "On 21 August 2019, the examining division issued a third communication pursuant to Rule 71(3) EPC expressing its intention to grant a European patent based on auxiliary request 2. In an annex, the examining division set out the reasons why it had admitted the third-party observations and why it considered the claims of the main request and auxiliary request 1 to be unclear and thus not allowable."
- " By letter dated 20 December 2019, the appellant indicated that it did not approve the text proposed for grant in the third communication pursuant to Rule 71(3) EPC. It requested a decision which could be appealed if the examining division was not able to grant a patent based on either the main request or auxiliary request 1."'
- "On 25 June 2020, the examining division issued the decision under appeal. The reasoning given for the admittance of the third-party observations and the non-allowability of the main request and auxiliary request 1 is an almost verbatim copy of the reasoning annexed to the third communication pursuant to Rule 71(3) EPC. Compared to the composition of the examining division which had conducted the oral proceedings and which had issued the third communication pursuant to Rule 71(3) EPC, the composition of the examining division which signed the decision under appeal was changed: the first examiner was no longer part of the division, the previous chairman had become the first examiner and a new chairman had been appointed."
- "It is established case law that a signed written decision issued after oral proceedings should be taken by the same members of the first-instance division who conducted the oral proceedings. If a change in the composition of the division occurs after oral proceedings, parties should therefore be offered new oral proceedings."
- "According to Article 18 EPC, oral proceedings should be held before the examining division itself. The right under Article 116(1) EPC to have oral proceedings can therefore only mean a right to have oral proceedings before the examining division in a composition which also takes the final decision on the case. If the division conducting the oral proceedings could be different from that taking the final decision, oral proceedings would be deprived of its purpose and Article 116(1) EPC would be meaningless."
- The decision is set aside, and the appeal fee is reimbursed.
- Compare T 0229/18, where the Chair of the Board retired between the oral proceeding and the issuing of the written decision. These two decisions may not be inconsistent with each other, but it is a rather delicate balance.
