Invention

Researchers, administrators, and TTO staff often use “invention” loosely to mean anything from a rough idea to a finished, patented product. For the purposes of a university technology transfer office and the Bayh-Dole Act, the term has a specific legal meaning that determines exactly when a disclosure obligation starts and whether federal funding rules apply at all.

The general patent-law definition

35 U.S.C. § 101 sets out the statutory basis: “Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor.” USPTO’s own applicant-facing guidance restates the same four categories as process, machine, article of manufacture, and composition of matter, plus improvements to any of them. Nothing in that definition requires the invention to be built, tested, filed, or even fully written down — it requires only that the inventor has conceived it.

Conception is the operative moment, not construction

Conception is the formation, in the inventor’s mind, of a definite and permanent idea of the complete and operative invention as it will be applied in practice. Courts and USPTO practice draw a firm line here: funding the work, supervising a lab, or carrying out someone else’s detailed instructions does not make a person an inventor, and identifying a problem or a research goal without a worked-out solution does not create an invention at all. Building or testing the thing — “reduction to practice” — can come later; filing a patent application is itself treated as a constructive reduction to practice. This is why TTOs ask researchers to disclose promptly once conception is complete and documentable (a dated notebook entry, a design that could be handed to someone skilled in the field to build), rather than waiting until a prototype exists. See CASRAI’s guide to invention disclosure for what researchers actually submit and why timing matters, and the worked invention disclosure form example for what that documentation looks like in practice.

“Invention” vs. Bayh-Dole’s “subject invention”

Not every invention triggers the Bayh-Dole Act. The Act, codified at 35 U.S.C. §§ 200–212, applies only to a subject invention: 35 U.S.C. § 201(e) defines that as any invention of a contractor (a university, other nonprofit organization, or small business, per 35 U.S.C. § 201(b)-(c)) conceived or first actually reduced to practice in the performance of work under a funding agreement — a grant, contract, or cooperative agreement with a federal agency. An invention conceived entirely on private or unrestricted institutional funds, with no federal funding agreement anywhere in its history of conception or first actual reduction to practice, is not a subject invention, even if it is patentable and disclosable under the university’s own intellectual property policy.

The distinction matters operationally. Where an invention is a subject invention, the standard patent rights clause implementing Bayh-Dole (37 CFR 401.14) obligates the university to disclose it to the funding agency — typically within two months of the inventor’s written disclosure to the institution’s designated patent-matters personnel — and sets deadlines for electing whether to retain title, filing patent applications, and preserving the government’s retained license. See CASRAI’s dictionary entry on the Bayh-Dole Act for the full election-of-title and government-license mechanics, and the guide to 35 U.S.C. § 102 patent novelty and invention disclosure timing for how disclosure timing interacts separately with the statutory bar on public disclosure before filing.

Joint inventorship

An invention can have more than one inventor. 35 U.S.C. § 116 permits inventors to apply jointly even where they did not work together physically or at the same time, did not each contribute the same type or amount of work, and did not each contribute to every claim — but each named inventor must have contributed to the conception of at least one claim in the resulting patent application. See CASRAI’s guide on co-inventors and the legal test for joint inventorship for how a TTO or patent counsel actually applies that test.

Why the definition matters for a TTO

Getting the definition right affects two very different failure modes. Treating a bare idea or research goal as a disclosable invention wastes TTO evaluation capacity and can create premature paper trails. Treating an already-conceived, documentable invention as “not yet real enough to disclose” risks a public-disclosure bar under 35 U.S.C. § 102 running before the institution has had a chance to file, and — where federal funding was involved — risks missing the Bayh-Dole disclosure clock entirely. Both are why most university IP policies define “invention” for internal disclosure purposes at least as broadly as the patent-law conception standard, rather than waiting for a working prototype.
