Headword
Opposition by patent proprietor

G 9/93 is a decision issued on 6 July 1994 by the Enlarged Board of Appeal of the European Patent Office (EPO). Unlike the revised European Patent Convention 2000, there used to be no explicit provision in the former European Patent Convention 1973 that allowed a patent proprietor to have one's own patent revoked. A patent proprietor may, however, seek a revocation of one's own patent. For example, the patent proprietor may want to avoid costly revocation proceedings concerning a patent owned by that proprietor. In an earlier decision G 1/84, the Enlarged Board of Appeal dealt with the issue of a patent proprietor opposing one's own patent and held such oppositions admissible. The Enlarged Board of Appeal dealt with the same issue again in later decision G 9/93 and it overruled its earlier decision G 1/84 thereby holding oppositions against one's own patents inadmissible.[1]

Practical aspects

A new provision in the form of Шаблон:EPC Article was introduced in consequence of the inadmissbiity of self-opposition under G 9/93.[3] Unlike the former EPC 1973, the revised EPC 2000 has a provision (Шаблон:EPC Article) allowing for revoking one's own patent. Accordingly, a patent proprietor can request revocation of their own patent via that provision instead of opposing their own patents.

In addition to the revocation provision in Шаблон:EPC Article, there also is a limitation procedure provided for in Шаблон:EPC Article. Accordingly, patent proprietors cannot only have their patents revoked; they can also have the scope of their European patents limited post-grant.
