306 Assignment of Division, Continuation, Substitute, and Continuation-in-Part in Relation to Parent Application [R-07.2015]
In the case of a division or continuation application, a prior assignment recorded against the original application is applied (effective) to the division or continuation application because the assignment recorded against the original application gives the assignee rights to the subject matter common to both applications. Although the assignment recorded against an original application is applied to the division or continuation application, the Office’s assignment records will only reflect an assignment of a division or continuation application (or any other application) if a request for recordation in compliance with 37 CFR 3.28, accompanied by the required fee (37 CFR 3.41), is filed.
In the case of a substitute or continuation-in-part application, a prior assignment of the original application is not applied (effective) to the substitute or continuation-in-part application because the assignment recorded against the original application gives the assignee rights to only the subject matter common to both applications. Substitute or continuation-in-part applications require the recordation of a new assignment if they are to be issued to an assignee, unless the substitute or continuation-in-part application is filed on or after September 16, 2012, and the assignee is the original applicant therein. See 37 CFR 3.81. See also MPEP § 307 and § 308.
