'''Reduction to practice''' transforms an idea into an invention that is ready to be patented by the [[United States Patent and Trademark Office]].Determination of priority—Reduction to practice, Patent Law Basics § 10:4 [[Patent|Patents]] protect an inventor's rights to their invention.''See'' U.S. Const. art. I, § 8, cl. 8. An invention, under U.S. law, must "refer to a concept that is complete, rather than merely one that is 'substantially complete'." Pfaff v. Wells Elecs., Inc., 525 U.S. 55, 60 (1998). Reducing a concept to practice is one way that inventors demonstrate that their invention is complete and thus ready to be patented to United States Patent and Trademark Office during the [[patent application]] process.Helsinn Healthcare S.A. v. Teva Pharms. USA, Inc., 586 U.S. 123, 130 (2019)

Prior to passage of the [[Leahy–Smith America Invents Act|American Invents Act]] (the "AIA"), reduction to practice was dispositive in determining [[Priority right|priority]] between competing inventors.Golden Bridge Tech., Inc. v. Apple Inc., 937 F. Supp. 2d 504, 516 (D. Del. 2013), adhered to on reconsideration (Apr. 25, 2013), aff'd, 758 F.3d 1362 (Fed. Cir. 2014) Priority establishes who can claim the patent rights to an invention invented by more than one person.''Id.'' Before 2013, the United States operated on a [[First to file and first to invent|first-to-invent]] system.Glob. Health Sols. LLC v. Selner, 148 F.4th 1363, 1367 (Fed. Cir. 2025) The person who reduced the concept to practice first, either actually or constructively, was entitled to the patent rights for that invention.Z4 Techs., Inc. v. Microsoft Corp., 507 F.3d 1340, 1352 (Fed. Cir. 2007) (quoting Monsanto Co. v. Mycogen Plant Sci., Inc.'','' 261 F.3d 1356, 1362 (Fed.Cir.2001)) Post-AIA however, the first inventor to file is entitled to the patent under the now [[First to file and first to invent|first-to-file]] system, even if the claimed invention was conceived earlier by a different inventor.Glob. Health Sols. LLC v. Selner, 148 F.4th 1363, 1367 (Fed. Cir. 2025); In re Samuels, No. 2022-1121, 2024 WL 960931, at *2 (Fed. Cir. Mar. 6, 2024) Thus, actually reducing to practice has become a moot vehicle in establishing patent priority.John DiGiancomo, ''Actual vs Constructive: The Death of Reduction to Practice in Patent Law'', Revision Legal, https://revisionlegal.com/patent/actual-vs-constructive-the-death-of-reduction-to-practice-in-patent-law/(April 19, 2021)

==== Actual Reduction to Practice ====

==== Actual Reduction to Practice ====

Actual reduction to practice is established when an inventor (1) "construct[s] an embodiment or perform[s] a process" that meets the claims and (2) "determine[s] that the invention would work for its intended purposes."Cooper v. Goldfarb, 154 F.3d 1321, 1327 (Fed. Cir. 1998). Essentially, the inventor demonstrates that they built the invention for the purposes outlined in the patent application. The inventor does not need to understand "why [their] invention works . . . to achieve an actual reduction to practice,"Teva Pharm. Indus. Ltd. v. AstraZeneca Pharms. LP, 661 F.3d 1378, 1383 (Fed. Cir. 2011) (quoting Parker v. Frilette, 462 F.2d 544, 547 (1972)) but must recognize the success of their invention in achieving its intended purpose.Estee Lauder Inc. v. L'Oreal, S.A., 129 F.3d 588, 592 (Fed. Cir. 1997)

L'Oreal, S.A., 129 F.3d 588, 592 (Fed. Cir. 1997) Testing is usually required to determine whether the invention works for its intended purpose, especially if the process is novel and the product of that process is useful for its intended purpose.Tennessee Valley Auth. v. Monsanto Chem. Co., 383 F.2d 973, 977 (5th Cir. 1967). The sufficiency of the testing depends on the factual circumstances of the case and courts employ a common sense approach to judge it.Scott v. Finney, 34 F.3d 1058, 1061 (Fed. Cir. 1994)

For biological materials, like bacteria and viruses, actual reduction to practice can be achieved by describing a microorganism deposit.MPEP § 2163''See'' 37 C.F.R. 1.801-1.809 As for computer simulations of an invention that meets all claim limitation, the Federal Circuit has yet to decide whether that suffices as actual reduction to practice.4 Annotated Patent Digest § 26:38.50 Post-AIA, it is unlikely the court would take up such a case.

==== Constructive Reduction to Practice ====

Constructive reduction to practice "occurs when a patent application on the claimed invention is filed."Solvay S.A. v. Honeywell Int'l, Inc., 622 F.3d 1367, 1376 (Fed. Cir. 2010) Under the Patent Act of 1952, a patent application must be accompanied by a specification.35 U.S.C. § 112(a) This specification requires "full, concise, and exact terms as to enable any person skilled in the art to which it pertains" to practice the invention.''Id.'' The publicly available specification is part of the constitutional bargaining between granting inventors a limited monopoly over their invention while "promot[ing] the progress of science and the useful arts."U.S. Const. art. I, § 8, cl. 8.Darlene M.J. Staines, ''The Patent Written Description Requirement: A Requirement in Search of a Description'', 92 Fordham L. Rev. 1196, 1200-1201.

This specification requires "full, concise, and exact terms as to enable any person skilled in the art to which it pertains" to practice the invention.''Id.'' A person skilled in the art is a hypothetical person with the requisite knowledge that can recreate the invention provided the specification is sufficiently detailed.''Helsinn Healthcare S.A. v. Teva Pharms. USA, Inc.,'' 586 U.S. 123, 139. The specification demonstrates to the United States Patent and Trademark Office that the
