Summary of Facts and Submissions

I. In a decision delivered orally on 19 February 1992, with written reasons posted on 5 May 1992 the Opposition Division rejected the opposition which had been filed against European patent No. 0 232 302 granted upon the subject matter of European patent application No. 86 904 301.8, and maintained the patent unamended.

II. The Opponent lodged an appeal against this decision on 9. July 1992, and filed on 11 September 1992 a written statement setting out the grounds of appeal and requesting the revocation of the patent in full.

III. In a letter dated 24 August 1994 the Proprietor stated that he no longer approves of the text of the patent as maintained by the Opposition Division and does not intend to supply amendments to the text. It was further stated that the patentee was hereby abandoning the patent and did not wish to defend the opposition before the Board of Appeal.

Reasons for the Decision

1. The appeal is admissible.

2. Since the Proprietor withdrew his approval of the text of the patent as granted and stated that he would not submit an amended text, there is no text of the patent on which the Board can consider the appeal. Since according to Article 113(2) EPC the European Patent Office must consider the European patent only in the text agreed by the proprietor of the patent, the patent cannot be maintained in any form and has, therefore, to be revoked; cf. T 73/84 (OJ EPO 1985, 241).

3. Moreover, the additional statement of the Proprietor that he abandons the patent makes it clear that the Proprietor agrees that the patent should be revoked. Said statement must therefore be considered equivalent to a request that the patent be revoked; cf. T 237/86 (OJ EPO 1988, 261).

ORDER

For these reasons it is decided that:

1. The decision under appeal is set aside.

2. The European patent No. 232 302 is revoked.
