How often are reserved sections in the MPEP updated or filled?

The frequency of updates to reserved sections in the MPEP varies and is determined by the USPTO based on several factors:

• Changes in patent laws or regulations
• New court decisions affecting patent examination
• Evolving USPTO policies and procedures
• Feedback from patent examiners and practitioners

Reserved sections may be filled or updated during regular MPEP revisions, which typically occur annually or as needed. However, there is no fixed schedule for updating specific reserved sections, and some may remain reserved for extended periods.
