Full Text Searchable MPEP edition 8:
PDF image CATPrep provides searchable copies of revisions of edition 8 of the Manual of Patent Examining Procedure as a service to the legal community, prospective USPTO registration examinees, and our Patent Bar Simulator software customers.

Please note that these files are large. Broadband users will need about 15 minutes to complete the download, and dial-up users of 56k modems may need more than 70 minutes. Most users can simply "right-click" the links below and select "Save-as" to save the file on their computer.

Please note that the 'MPEP Viewer' available on test day is based on Adobe Acrobat Reader 5, which is not the latest version. Recent versions of Acrobat Reader provide a new search interface. To emulate the search function available on test day, we recommend only using version 5 which is freely available here.

the MPEP Edition 8 Revision 3 as a single file (~21MB) multiple files (~26MB)

Please Note: The computer-delivered USPTO registration exam is currently proctored at locations with access to a copy of the Manual of Patent Examining Procedure (MPEP) that can only be searched for specific text one chapter at a time. The copies of the MPEP provided here are actually easier to search than the ones available during the actual exam because they support the ability to search the MPEP in its entirety.

To emulate the same chapter-by-chapter MPEP search available during the actual exam, you should download the MPEP Edition 8 Revision 4 in multiple files (linked above) and use Adobe Acrobat Reader 5 (also linked above) to view and search each chapter of the MPEP.

Quick MPEP Page & Section Search:
Use this search to find the pages on which a specific phrase appears and then jump (Ctrl+N in Acrobat Reader) directly to that page in our single file versions of the MPEP. This quick search is also integrated into the menu of our Patent Bar Simulator. Both MPEP eight edition revisions 3 and 4 may be searched using the form below.


We hope that you will find our offerings valuable tools in your preparation for the USPTO Registration Examination. If you encounter any problems or have any questions regarding our software or services you will most likely find an answer or solution on our Help & Frequently Asked Questions page, but if you have a concern not addressed there please feel free to 'Contact Us'.
