In accordance with the patent laws, rules and procedures as related in the MPEP, which of the following statements regarding operability or enablement of a prior art reference is the most correct?
  1. The level of disclosure required for a reference to be enabling prior art is no less if the reference is a United States patent than if it is a foreign patent.
  2. A reference is not presumed to be operable merely because it expressly anticipates or makes obvious all limitations of an applicant’s claimed apparatus.
  3. A non-enabling reference may not qualify as prior art for the purpose of determining anticipation or obviousness of the claimed invention.
  4. A reference does not provide an enabling disclosure merely by showing that the public was in possession of the claimed invention before the date of the applicant’s invention.
  5. All of the above are correct.
Explanation
Answer: A - MPEP § 2121, under the heading “What Constitutes An ‘Enabling Disclosure’ Does Not Depend On The Type Of Prior Art The Disclosure Is Contained In,” states, in reliance upon In re Moreton, 288 F.2d 708, 711, 129 USPQ 227, 230 (CCPA 1961): “The level of disclosure required within a reference to make it an ‘enabling disclosure’ is the same no matter what type of prior art is at issue.... There is no basis in the statute (35 U.S.C. 102 or 103) for discriminating either in favor of or against prior art references on the basis of nationality.” Answer (B) is incorrect. MPEP § 2121, under the heading “Prior Art Is Presumed To Be Operable/Enabling,” states that “[w]hen the reference relied on expressly anticipates or makes obvious all of the elements of the claimed invention, the reference is presumed to be operable.” Answer (C) is incorrect. MPEP § 2121.01, under the heading “35 U.S.C. 103 Rejections And Use Of Inoperative Prior Art,” quotes Symbol Technologies Inc. v. Opticon Inc., 935 F.2d 1569, 1578, 19 USPQ2d 1241, 1247 (Fed. Cir. 1991) as stating that “a non-enabling reference may qualify as prior art for the purpose of determining obviousness under 35 U.S.C. 103.” Answer (D) is incorrect. MPEP § 2121.01 states that “[a] reference contains an ‘enabling disclosure’ if the public was in possession of the claimed invention before the date of invention.” Answer (E) is incorrect because answers (B), (C) and (D) are incorrect.
