Restriction practice in the context of potential interferences is addressed in MPEP 2303 . The section states: “ Potential interferences present an additional situation in which a restriction requirement may be appropriate. Specifically, restriction of interfering claims from non-interfering claims, or from unpatentable claims whose further prosecution would unduly delay initiation of an interference, can be an appropriate use of restrictions under 35 U.S.C. 121. “ This means that examiners may use restriction requirements to separate interfering claims from non-interfering claims or unpatentable claims that could delay the interference process. It’s recommended to consult an Interference Practice Specialist (IPS) when making such restrictions.
