Article 47 Request for correction of error

Without prejudice to rule 45(3), a request for the correction of an error in the register or in any document filed at the Patent Office in connection with registration shall be made on Patents Form 11/77; and the correction shall be clearly identified on a document annexed to the form or, if not, on the form itself.

The comptroller may call for such written explanation of the reasons for the request or evidence in support of it as he may require in order to satisfy himself that there is an error and, upon being so satisfied, shall make such correction as may be agreed between the proprietor of the patent or applicant and the comptroller.
