This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

37 CFR 1.142(b) is a crucial regulation in the context of restriction requirements. It provides examiners with the authority to enforce restriction requirements and manage non-elected claims. The significance of this regulation includes:

• It gives examiners the power to cancel non-elected claims when the applicant fails to do so after a final restriction requirement.
• It supports the efficient examination process by allowing examiners to focus on the elected claims.
• It helps maintain the integrity of the restriction requirement process.

As referenced in MPEP 821.01: “Claims to the nonelected invention should be treated as indicated in 37 CFR 1.142(b).” This regulation ensures that applicants comply with restriction requirements and that patent applications proceed efficiently through the examination process.
