The sole purpose of the title is to inform the public about the technical information disclosed in the application. The title has no bearing on the content of the application as filed or on the protection conferred by the patent, once granted. Furthermore, the title is not part of the documents to be approved by an applicant before a patent can be granted.
Thus the ultimate responsibility for the title rests with the division, and it is within the division's discretion to accept or not any request from the applicant for a change in the title (see also A‑III, 7).
