How often is the Manual of Patent Examining Procedure (MPEP) updated?

The Manual of Patent Examining Procedure (MPEP) is regularly updated to reflect changes in patent laws, rules, and procedures. According to MPEP 101:

The Manual is updated periodically to include changes in patent laws and rules and also changes in Patent and Trademark Office procedures.

While the MPEP doesn’t specify an exact frequency for updates, they typically occur:

• Multiple times per year to incorporate new policies and procedures
• After significant changes in patent laws or regulations
• When court decisions impact patent examination practices

Users should always refer to the most recent version of the MPEP available on the USPTO website for the most up-to-date information.
