(a)if issue has been joined on the application before the appointed day, the application, any appeal from the comptroller’s decision on it and any further appeal shall be prosecuted under the old law, but as if references in the 1949 Act and rules made under it to the Appeal Tribunal were references to the Patents Court;
(b)if issue has not been so joined, the original application shall be taken to be an application under section 33 of the 1949 Act for the revocation of the patent on whichever of the grounds referred to in section 32(1) of that Act corresponds (in the comptroller’s opinion) to the ground on which the original application was made, or, if there is no ground which so corresponds, shall be taken to have abated immediately before the appointed day.
