Question 31
Domain 2: Patent Application Filing and Claim DraftingWhat is the broadest reasonable interpretation (BRI) standard used for during patent examination?
Correct answer: B
Explanation
During patent examination, the USPTO applies the broadest reasonable interpretation standard to claim language so examiners can assess patentability before issuance. This means claims are construed during prosecution at the USPTO, not narrowly as in litigation, to ensure the application is examined against the full scope reasonably supported by the words used.
Why each option is right or wrong
A. Determining patent infringement in litigation
B. Construing patent claims during prosecution at the USPTO
Under USPTO examination practice, the broadest reasonable interpretation standard is applied when an examiner interprets claim language during prosecution, before a patent issues. The rule is reflected in 37 C.F.R. § 1.104 and longstanding USPTO examination procedure, which requires claims to be read as broadly as reasonably supported by the specification so the Office can determine patentability on the record before allowance.
C. Calculating patent damages
D. Evaluating patent term extensions
