Patent Claims Flashcards

Which of the following best describes an 'omnibus claim' as used in some foreign patent systems?

Answer: A claim that covers all embodiments in the specification by direct reference to the drawings

An omnibus claim refers directly to the specification and drawings without reciting specific elements, a practice not permitted by the USPTO.

In patent claim drafting, antecedent basis requires that:

Answer: A term using 'the' or 'said' must have been introduced earlier in the claim with 'a' or 'an'

Proper antecedent basis requires that a claim element be introduced with 'a' or 'an' before it is referenced with 'the' or 'said' to avoid indefiniteness.

A claim that recites a step of 'heating the composition to a temperature sufficient to cause reaction' most likely satisfies § 112(b) when:

Answer: A person of ordinary skill in the art would know what temperature is required based on the disclosure

Functional language like 'sufficient to cause reaction' is definite when a person of ordinary skill would understand the scope based on the specification and knowledge in the art.

When claims are rejected under § 112(a) for lack of written description, the examiner must show that:

Answer: One skilled in the art would not recognize that the inventor had possession of the claimed invention

A written description rejection requires showing that the specification would not convey to skilled artisans that the inventor possessed the claimed invention at the time of filing.

Which of the following situations creates a new matter issue under 35 U.S.C. § 132?

Answer: Adding a new example to the specification that was not in the original application

Adding substantive content—such as a new example—to the specification that was not present in the original disclosure constitutes new matter prohibited by § 132.

A claim reciting 'a widget having a diameter of 5 cm' and a prior art reference disclosing 'a widget having a diameter of approximately 5 cm' would likely result in:

Answer: Anticipation because the claimed value falls within the prior art disclosure

When a prior art reference discloses a range or approximation that encompasses the claimed value, the prior art anticipates the claim.

Under the broadest reasonable interpretation (BRI) standard used during prosecution, claim terms are given:

Answer: Their broadest reasonable meaning consistent with the specification

During prosecution, the USPTO applies BRI, giving claim terms their broadest reasonable interpretation consistent with the specification as understood by one skilled in the art.
