|}

G 1/84 is a decision of the Enlarged Board of Appeal of the European Patent Office (EPO), which was issued on July 24, 1985. The Board held in this decision that:

: "A notice of opposition against a European patent is not inadmissible merely because it has been filed by the proprietor of that patent."

The decision was overruled in G 9/93, a later decision in which the Enlarged Board held that a European patent cannot be opposed by its own proprietor.
