Summary of Facts and Submissions

I. In an interlocutory decision dated 9 August 1993, the Opposition Division decided that the patent No. 0 282 165, as amended by the proprietor, met the requirements of the EPC.

II. The Opponent appealed against this decision by a letter filed on 9 September 1993, paid the fee for appeal and filed a Statement of Grounds of Appeal on the same date. He requested that the patent be revoked.

III. In a letter dated 20 December 1995 the Patentee (Respondent) stated: "we hereby formally request that the above-identified patent be revoked."

Reasons for the Decision

1. The appeal complies with Articles 106 to 108 and Rule 64 EPC and is admissible.

2. The Patentee (Respondent) has made clear in his letter dated 20 December 1995 that he wishes his patent to be revoked. The Board can therefore in exercise of its power under Article 111(1) EPC decide to revoke the European patent (see Decisions T 186/84, OJ EPO 1986, 79 and T 237/86, OJ EPO 1988, 261).


For these reasons it is decided that:

The decision of the Opposition Division is set aside and the European patent No. 0 282 165 is revoked.
