Question 34
Domain 3: Patent Prosecution and MPEP-Based PracticeWhich of the following is NOT a basis for filing a restriction requirement?
Correct answer: C
Explanation
A restriction requirement is proper only when the claims are to "independent and distinct inventions." Claims that are directed to overlapping subject matter are not distinct, so they do not provide a basis for restriction. Overlap means the claims are too closely related to be separated into different inventions.
Why each option is right or wrong
A. The application claims two distinct inventions
B. The application claims two independent inventions
C. The claims are directed to overlapping subject matter
Under 35 U.S.C. § 121 and MPEP § 803, a restriction requirement is authorized only when the examiner can identify independent and distinct inventions, not merely related claims. Claims that overlap in subject matter are not “distinct” for restriction purposes; overlap instead indicates the claims are too closely related to justify forcing an election between them.
D. The application claims a combination and a subcombination that are separately patentable
