Industrial and Commercial Property (Protection) Act, 1927

Single patent for cognate inventions.

31.—(1) Where the same applicant has put in two or more provisional specifications for inventions which are cognate or modifications one of the other, and has obtained thereby concurrent provisional protection for the same, and the controller is of opinion that the whole of such inventions are such as to constitute a single invention and may properly be included in one patent, he may accept one complete specification in respect of the whole of such applications and grant a single patent thereon.

(2) Such patent shall bear the date of the earliest of such applications, but in considering the validity of the same, and in determining other questions under this Act, the court or the controller, as the case may be, shall have regard to the respective dates of the provisional specifications relating to the several matters described therein.
