Rule 50 Revocation of patents

On any appeal under sections 12 and 13 of the Administration of Justice Act 1969^f1 from an order for revocation of a patent, the appellant must serve notice of the appeal on the Comptroller-General, Intellectual Property Office (“the Comptroller”) as well as on every respondent.

A respondent who decides not to oppose the appeal must serve notice of that decision on the Comptroller together with the relevant statements of case.

The Comptroller must within 14 days serve on the appellant and file a notice stating whether or not the Comptroller intends to appear on the appeal.

Where notice is given under paragraph (3), the Comptroller may appear on the appeal.
