R 4/17 - Four is a party
In the present case, the Opponent appealed the decision of the Opposition Division to maintain the patent as granted. The Board of Appeal sent three registered - but without advice of delivery - communications (notice of appeal; statement of the grounds of appeal; further letter) to the Respondent-Proprietor. In the absence of any response from the Proprietor to these letters, the Board of Appeal considered itself to be in a position to issue a decision revoking the patent without the need to hold oral proceedings. This decision of the Board was sent to the parties under cover of a registered letter with advice of delivery.
The Proprietor filed a petition for review of the decision, arguing that it had no record of ever having received the first three letters, thus depriving him of his right to be heard.
The Enlarged Board now deals with this petition for review, and finds that in the present case, the Proprietor had, within the meaning of Article 113(1) EPC, no opportunity at all to comment on the grounds for the decision under review. This qualifies as a fundamental violation of his right to be heard.
Catchwords:
In the event of any dispute about whether a letter from the EPO reached the addressee or on which date, it is incumbent on the EPO to establish that the letter has reached its destination or to establish the date on which the letter was delivered to the addressee (Reasons, point 2).
[...] parties must be able to rely on the EPO complying with the relevant provisions of the EPC and, at least for the purposes of Article 113(1) EPC, they and their representatives have no duty to monitor the proceedings themselves by regularly inspecting the electronic file (Reasons, point 4).
In respect of the implausibility of the non-arrival of letters put forward by the Other Party the Enlarged Board considers that it cannot be expected that the Petitioner should prove a negative, that is the nonreceipt of a letter, or provide a plausible explanation for non-receipt (Reasons, point 4).
