Question 29
Domain 2: Patent Application Filing and Claim DraftingWhat distinguishes a continuation-in-part (CIP) from a regular continuation application?
Correct answer: B
Explanation
A continuation-in-part differs because it includes new subject matter while still claiming priority to the earlier filing. A regular continuation must be based on the same disclosure as the parent, but a CIP "adds new matter not disclosed in the parent application."
Why each option is right or wrong
A. A CIP must be filed by a different inventor
B. A CIP adds new matter not disclosed in the parent application
Under 35 U.S.C. § 120 and 37 C.F.R. § 1.53(b), a regular continuation must be filed while the earlier application is pending and may claim the parent’s filing date only for subject matter already disclosed there. A continuation-in-part is different because it is permitted to include additional disclosure not present in the parent; that new matter gets only the CIP’s filing date, while the earlier disclosure can still rely on the parent date.
C. A CIP has a different examiner than the parent
D. A CIP cannot claim the benefit of the parent filing date
