Summary of Facts and Submissions

I. An appeal was lodged by the Appellant/Opponent against the decision of 20 September 1989 of the Opposition Division, which maintained European patent No. 35 269 in amended form, requesting that the decision be set aside and the patent revoked.

II. In a letter submitted on 9 September 1992 the Respondent/Patentee stated the following:

"... we request that the patent be revoked".

Reasons for the Decision

1. The appeal is admissible.

2. The Patentee has made it clear in his letter received on 9 September 1992 that he wishes his patent to be revoked.

The Board can therefore in the exercise of its power under Article 111(1) EPC decide to revoke the European patent (see Decision T 237/86, OJ EPO 1988, 261).


For these reasons, it is decided that:

1. The decision under appeal is set aside.

2. European patent No. 35 269 is revoked.
