806.05 Related Inventions - 800 Restriction in Applications Filed Under 35 U.S.C. 111; Double Patenting


806.05 Related Inventions

Where two or more related inventions are being claimed, the principal question to be determined in connection with a requirement to restrict or a rejection on the ground of double patenting is whether or not the inventions as claimed are distinct. If they are distinct, restriction may be proper. If they are not distinct, restriction is never proper. If nondistinct inventions are claimed in separate applications or patents, double patenting must be held, except where the additional applications were filed consonant with a requirement to restrict in a national application.

The various pairs of related inventions are noted in the following sections.
