Question 4
Domain 2: Patent Application Filing and Claim DraftingWhich of the following is true about the requirement for drawings in a patent application?
Correct answer: B
Explanation
35 U.S.C. § 113 provides that the applicant "shall furnish a drawing where necessary for the understanding of the subject matter sought to be patented." That means drawings are not always required, but they are required whenever they are needed to understand the invention.
Why each option is right or wrong
A. Drawings are always optional
B. Drawings are required when necessary for understanding the invention under 35 U.S.C. § 113
35 U.S.C. § 113 states that the applicant must furnish a drawing when it is necessary for understanding the subject matter sought to be patented; the statute does not impose a universal drawing requirement in every application. In practice, the USPTO treats drawings as mandatory only if they are needed to make the disclosure intelligible, so the controlling condition is necessity for comprehension rather than the mere filing of a patent application.
C. Drawings are required only for design patents
D. Drawings must be in color
