Manual of Patent Examining Procedure

This is the 3,200+ page Manual of Patent Examining Procedure used by every US Patent Examiner to learn and reference while they do their jobs. Its importance can't be understated as it relates to the examination process undertaken by the examiners. 

This is only published when the USPTO releases a new edition, and features:

  • A SINGLE VOLUME with full sized 8.5" x 11.0" Letter sized pages
  • When space allows, we add a comprehensive Table of Contents
    (see Status page for current release - link at bottom of page)
  • Includes Complete PDF on CD-ROM with forms
  • Minimum font size of main text is 10 points (any larger will force 2 volumes).
  • The appendices of the MPEP contain a copy of the following manuals:
       - Appendix R  - 37-CFR  (Rules & Regs),
       - Appendix L  - US Code (Laws),
       - Appendix T  - Patent Cooperation Treaty (PCT)
       - Appendix AI - Administrative Instruction Under the PCT
       - Appendix P  - Paris Convention for the Protection of Industrial Property
       Please note that the manual copies are often not the most recent
       editions available. They were added when the USPTO originally
       assembled the currently available version of the MPEP. Which may not be
       reissued for up to 2 years.

The current edition, date of publication (month and year) along with availability and prices are listed on the Book Prices & Status page (1st button below) or go directly to one of the order forms with the Order Buttons (below center and right):

Cooperative Patent Classification System


In September 2014, the USPTO and KIPO (Korean IP Office) inked an agreement to work together on the CPC. KIPO will fully CPC classify all new patent applications and utility models, but no mention of back-file data. The CPC system is gaining wide acceptance. It definitely has the detail needed to replace the US system, and then some. We're still studying and learning the details, and the USPTO decision for the two year overlap (CPC/USC) makes more sense to us (it gives us more time, too. 1 year down, 1 to go). The EPO seems to have completed most, if not all of the their ECLA to CPC translations and CPC assignments, and unlike the ECLA data, the EPO's CPC data have been added to DOCDB for all countries they handle. We think it's a wonderful addition to the data, and our compliments and thanks go to the EPO!
