Explanation
Answer: B - MPEP § 2111.03 (fourth paragraph) states, in reliance upon In re Herz, 537 F.2d 549, 551-52, 190 USPQ 461, 463 (CCPA 1976), that “[t]he transitional phrase ‘consisting essentially of’ limits the scope of a claim to the specified materials or steps ‘and those that do not materially affect the basic and novel characteristic(s)’ of the claimed invention.” (A) is incorrect. The statement is contradicted by MPEP § 2111.03 (second paragraph), which states, in reliance upon Genentech, Inc. v. Chiron Corp., 112, F.3d 495, 501, 42 USPQ2d 1608, 1613 (Fed. Cir. 1997) that “[t]he transition term ‘comprising’, which is synonymous with ‘including,’ ‘containing,’ or ‘characterized by,’ is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. (C) is incorrect. The statement is contradicted by MPEP § 2111.03 (third paragraph), which states, in reliance upon In re Gray, 53 F.2d 520, 11 USPQ 255 (CCPA 1931) that “[t]he transitional phrase ‘consisting of’ excludes any element, step , or ingredient not specified in the claim.” (D) is incorrect. The statement is directly contradicted by MPEP § 2111.03 (third paragraph), which states “[a] claim which depends from a claim which ‘consists of’ the recited elements or steps cannot add an element or step.” (E) is incorrect because (A), (B) and (C) are incorrect.
