Opinion

T.S. Ellis, III, United States District Judge

This is an appeal from a decision by the United States Patent & Trademark Office ("PTO"), calculating the patent term adjustment for United States Patent No. 8,981,063, owned by plaintiff, the Mayo Foundation for Medical Education and Research ("Mayo"). Specifically, the PTO determined that the six-month period extending from the conclusion of the interference proceeding until the PTO's mailing of the notice of allowance constituted "time consumed by continued examination requested by the applicant" pursuant to 35 U.S.C. § 154(b)(1)(B). Accordingly, the PTO excluded this period from the patent term adjustment calculation. Mayo argues that the PTO erred in excluding this time period from its adjustment calculation because the applicant's requested "continued examination" ended when the interference was declared. This dispute has been fully briefed and argued and is now ripe for disposition.

I.

Because Congress has relatively recently altered the patent law landscape in a manner particularly pertinent to this appeal, a brief description of this new landscape provides necessary context for resolution of the issues here.

The patent process begins when an applicant seeking a United States patent files an application with the PTO. See *42835 U.S.C. § 111. The PTO then conducts an examination of that application, reviewing the application first for procedural requirements and then referring the application to an examiner to determine whether the claimed invention meets substantive patentability requirements. Id. §§ 101, 112, 103, 131. If the examiner determines that an applicant is entitled to a patent, a written notice of allowance is given or mailed to the applicant. Id. § 151. If, on the other hand, the examiner determines that the application does not meet patentability requirements, the examiner sends the applicant a notice rejecting the application and explaining the reasons for the rejection. See id. § 132(a). The applicant may then appeal the determination to the Patent Trial and Appeal Board ("PTAB") or file a request for continued examination ("RCE") of the application pursuant to 35 U.S.C. § 132(b). See 37 C.F.R. § 1.114. When an applicant files an RCE, the PTO withdraws the finality of the rejection, and an examiner continues examination of the application. See Id. § 1.114(d).

Throughout this process, the examiner or the applicant can also recommend an application for an "interference" proceeding. See 35 U.S.C. § 135(a) ; see also 37 C.F.R. § 41.202(a).2 Where two parties claim the same patentable invention, an interference proceeding serves to determine which party is entitled to priority of invention. See Rolls-Royce, PLC v. United Techs. Corp. , 603 F.3d 1325, 1330 (Fed. Cir. 2010). Because interference proceedings are costly and time-consuming, examiners generally must complete examination or reexamination of the application before an interference is declared, and there must be at least one claim that "(1) [i]s patentable but for judgment in the contested case, and (2) [w]ould be involved in the contested case." 37 C.F.R. § 41.102.3

Once an interference is declared, the PTAB takes evidence and "enters final judgment on questions of priority and patentability arising in an interference." Manual of Patent Examining Procedure (" MPEP") § 2301.4 Generally, the examiner will not examine the application again until after the interference concludes.5 At that point, the application returns to the examiner, who then takes action, depending on the judgment in the interference proceeding. See id. If the PTAB's judgment contains a recommendation for further action, the examiner must reopen prosecution to consider the recommendation. See id. § 2308. Specifically, the PTAB may recommend rejection of a claim in which case the examiner generally must issue the recommended rejection. See 37 C.F.R. § 41.127(c). If, on the other hand, the PTAB determines that the applicant has priority with respect to a claim, the examiner "should update the search and *429may, but is not required to, reopen prosecution for any claim not disposed of in the judgment." See MPEP § 2308 ; see id. § 2301.

If, at the end of this process, a patent issues, the patent term will last for twenty years from the date the initial patent application was filed. Prior to 1994, patent terms were seventeen years from the date the patent issued. In 1994, Congress changed the patent term to twenty years from the date the application was first filed.
