 About the MPEP

The Manual of Patent Examining Procedure (MPEP) is published to provide USPTO patent examiners, applicants, attorneys, agents and representatives of applicants with a reference work on the practices and procedures relative to the prosecution of patent applications before the USPTO. The MPEP contains instructions to patent examiners, as well as other material in the nature of information and interpretation, and outlines the current procedures which the patent examiners are required or authorized to follow in appropriate cases in the examination of a patent application. The MPEP does not have the force of law or the force of the rules. The MPEP is available in both paper and electronic form.

Suggestions for improving the form and content of the MPEP are always welcome. They should be addressed to: Mail Stop MPEP, Commissioner for Patents, P.O. Box 1450, Alexandria, VA 22313-1450 or sent via e-mail to:
