What are the general principles for determining distinctness or independence of claimed inventions?

The Manual of Patent Examining Procedure (MPEP) outlines several key principles for determining the distinctness or independence of claimed inventions:

• When the USPTO requires restriction, double patenting cannot be held.
• It is crucial that a restriction requirement is never made when related inventions, as claimed, are not distinct.
• For specific criteria on distinctness, the MPEP directs examiners and applicants to sections 806.05 through 806.05(j) and 809.03.
• The criteria for patentably distinct inventions are found in MPEP § 802.01.

As stated in MPEP § 806:

“Where restriction is required by the Office double patenting cannot be held, and thus, it is imperative the requirement should never be made where related inventions as claimed are not distinct.”

This emphasizes the importance of proper distinctness determination to avoid unnecessary restrictions and potential double patenting issues.
