76 Power to correct clerical errors, etc.

(1) The comptroller may, in accordance with the provisions of this section, correct any clerical error in any patent, any application for a patent or any document filed in pursuance of such an application, or any error in the register of patents.

(2) A correction may be made in pursuance of this section either upon a request in writing made by any person interested and accompanied by the prescribed fee, or without such a request.

(3) Where the comptroller proposes to make any such correction as aforesaid otherwise than in pursuance of a request made under this section, he shall give notice of the proposal to the patentee or the applicant for the patent, as the case may be, and to any other person who appears to him to be concerned, and shall give them an opportunity to be heard before making the correction.

(4) Where a request is made under this section for the correction of any error in a patent or application for a patent or any document filed in pursuance of such an application, and it appears to the comptroller that the correction would materially alter the meaning or scope of the document to which the request relates, and ought not to be made without notice to persons affected thereby, he shall require notice of the nature of the proposed correction to be advertised in the prescribed manner.

(5) Within the prescribed time after any such advertisement as aforesaid any person interested may give notice to the comptroller of opposition to the request, and where such notice of opposition is given the comptroller shall give notice thereof to the person by whom the request was made, and shall giv6 to him and to the opponent an opportunity to be heard before he decides the case.
