Summary of Facts and Submissions

I. In an interlocutory decision dated 11 July 1990, the Opposition Division decided to maintain the patent No. 0 070 435 in amended form.

II. The Appellant appealed against this decision by a letter filed on 4 September 1990, paid the fee for appeal on the same date and filed a statement of grounds of appeal on 20 November 1990.

III. In a letter dated 22 July 1991 the Respondent stated:

"Patentee herewith requests revocation of the above- mentioned European Patent."

Reasons for the Decision

1. The patentee has made it clear in his letter received on 22 July 1991 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:

The decision of the Opposition Division dated 11 July 1990 is set aside and European patent No. 0 070 435 is revoked.
