7 CFR § 97.105 - Denial of an application.
(b) In denying an application, the examiner shall cite the reasons the application was denied. When a reason involves the citation of certain material which is complex, the particular part of the material relied on shall be designated as nearly as practicable. The pertinence of each reason, if not obvious, shall be clearly explained.
(c) If prior domestic certificates are cited as a reason for denial, their numbers and dates and the names of the owners shall be stated. If prior foreign certificates or rights are cited, as a reason for denial, their nationality or country, numbers and dates, and the names of the owners shall be stated, and such other data shall be furnished, as may be necessary to enable the applicant to identify the cited certificates or rights.
(d) If printed publications are cited as a reason for denial, the author (if any), title, date, pages or plates, and places of publication, or place where a copy can be found shall be given.
(e) When a denial is based on facts known to the examiner, and upon request by the applicant, the denial shall be supported by the affidavit of the examiner. Such affidavit shall be subject to contradiction or explanation by the affidavits of the applicant and other persons.
(f) Abandoned applications may not be cited as reasons for denial.
