55. Term of patents of addition
(1) A patent of addition shall be granted for a term equal to that of the patent for the main invention, or so much thereof as has not expired, and shall remain in force during that term or until the previous cesser of the main patent, and no longer:
Provided that if the main patent is revoked, the court or Controller, on the patentee’s request, may order that the patent of addition become an independent patent for the remainder of the main patent’s term, and it shall continue in force accordingly.
(2) No renewal fees are payable for a patent of addition, but if it becomes an independent patent under sub-section (1), the same fees become payable thereafter as if originally granted as an independent patent.
