704.12(a)    Relationship of Requirement for Information to Duty of Disclosure [R-08.2012]

The duty of candor and good faith under 37 CFR 1.56 applies to the applicant’s reply to a requirement for information under 37 CFR 1.105, and requires that the applicant reply to a requirement under 37 CFR 1.105 with information reasonably and readily available.

37 CFR 1.56 requires parties identified in 37 CFR 1.56(c) to disclose to the Office information material to the patentability of the claimed subject matter. This threshold is substantially higher than that for requiring information under 37 CFR 1.105, which is reasonable necessity to the examination of the application. See, e.g., Star Fruits S.N.C. v. United States, 280 F.Supp.2d 512, 515-16 (E.D. Va 2003)("Beyond that which a patent applicant is duty-bound to disclose pursuant to 37 CFR 1.56, an examiner may require the production of ‘such information as may be reasonably necessary to properly examine or treat the matter.’")

In contrast with the applicant’s duty to disclose on his or her own initiative information material to patentability under 37 CFR 1.56, the Office has the authority to require information reasonably necessary to the examination or treatment of a matter in an application. Such information may not be considered material to patentability by applicant, hence applicant would not be required to provide the information under 37 CFR 1.56. The information is instead reasonably necessary to determine the state of the art, the context in which the invention is practiced, the directions in which the relevant art are advancing, the similarity between the claimed subject matter and other art worked on by the applicants and their assignees or to otherwise proceed in the examination and treatment of matters in an application.

Similar to 37 CFR 1.56, applicant is required by 37 CFR 1.105 to submit information already known, but there is no requirement to search for information that is unknown. Unlike 37 CFR 1.56, applicant is required by 37 CFR 1.105 to submit information that may not be material to patentability in itself, but that is necessary to obtain a complete record from which a determination of patentability may be determined.
