An invention disclosure is the internal document a researcher submits to a technology transfer office (TTO) reporting a new discovery, but “invention disclosure” as a concept and “invention disclosure form” as a document are different questions. The concept is covered in CASRAI’s dictionary; this guide answers the second, more practical question: what fields does an actual invention disclosure form contain, and what does a properly filled-in one look like, section by section.
This is an illustrative, composite example, not a real institution’s form. The field structure below reflects the common core found across published university invention disclosure forms (the pattern is consistent enough across institutions that AUTM treats disclosure-intake as a defined step in its own technology-transfer curriculum), but institutions vary in exact wording, ordering, and any additional fields their counsel requires. “Meridian State University” is the same fictional composite institution used elsewhere in CASRAI’s tech-transfer guides. Nothing on this page is legal advice; always use your own institution’s actual form and consult your TTO before disclosing.
What the form is for
An invention disclosure form does two jobs at once. First, it is the intake mechanism a TTO uses to evaluate a discovery: is it patentable, who owns it, is it worth the cost of protecting, and who might license it. Second, where the work was federally funded, it is the document that starts the institution’s Bayh-Dole Act compliance clock — the Act requires a contractor to disclose each “subject invention” to the funding agency “within a reasonable time” (35 U.S.C. §202), and the standard implementing patent rights clause at 37 CFR 401.14(c) ties specific deadlines (commonly a two-month window from the inventor’s internal disclosure, then up to a two-year election-of-title window) to that disclosure date. Filling the form out late, or not at all, can jeopardize the institution’s ability to retain title to a federally funded invention.
Section 1: Invention title and inventors
Every form opens with a short working title for the invention and a full list of contributors who believe they helped conceive it or reduce it to practice. Determining inventorship correctly matters legally, not just administratively — U.S. patent law defines an inventor as someone who contributed to the conception of at least one claim, which is a narrower and more specific test than “who worked on the project” or “whose name goes on the resulting paper.” Each listed inventor typically provides their department, institutional email, and citizenship (citizenship affects export-control and foreign-filing considerations).
Illustrative filled-in example:
Working Title: Low-power sensor array for continuous glucose monitoring
Inventor 1: Department of Bioengineering, Meridian State University — role: conceived the sensor architecture and led circuit design
Inventor 2: Department of Chemistry, Meridian State University — role: developed the enzyme-immobilization coating and ran the validation assays
Section 2: Conception and reduction-to-practice dates
This section asks for the date the idea was first conceived (with a specific, sufficiently complete mental picture of how to make and use it) and the date it was first reduced to practice — either actually built and tested, or “constructively” reduced to practice by filing a patent application describing it. Under current, post-America Invents Act U.S. law these dates matter less for determining who “wins” a priority dispute (the U.S. is now a first-inventor-to-file system) than they once did, but they still matter for two other reasons: they anchor the one-year prior art/statutory-bar clock under 35 U.S.C. §102(b) once a public disclosure happens, and under 37 CFR 401.14(c)(2) they can compress the Bayh-Dole election-of-title window to as little as 60 days before that one-year bar runs out. A well-kept, contemporaneous lab notebook record is usually the actual evidence behind whatever dates go in this section.
Illustrative filled-in example:
Conception date: March 3, 2026 (per ELN entry #4471)
First reduction to practice: June 18, 2026 (first working bench prototype tested)
Section 3: Description of the invention
This is the substantive core of the form: what the invention is, what problem it solves, how it works, and what makes it different from existing approaches. TTOs generally ask for enough technical detail that a patent attorney could draft a provisional application from it without needing a full follow-up interview, plus any known alternative approaches or competing products. Vague descriptions are the single most common reason a disclosure comes back for revision before triage can even begin.
Illustrative filled-in example:
Description: A flexible sensor array using a novel enzyme-immobilization coating that extends continuous glucose monitor sensor life from the current industry-typical 10-14 days to a target of 30+ days, reducing the frequency of sensor replacement for patients. Differs from existing CGM sensors by [technical mechanism]. Known competing approaches: [list of comparable commercial or published sensors and how this differs].
Section 4: Prior public disclosure and planned publication
This section asks whether the invention has already been publicly disclosed — a conference talk, a poster, a preprint, a thesis defense, a sales demo, even a sufficiently detailed conversation with someone outside a confidentiality obligation can count — and whether any publication, presentation, or thesis defense is planned and when. This is one of the most time-sensitive fields on the entire form: under 35 U.S.C. §102(b), a public disclosure starts a one-year grace period in the U.S. (many other countries have no grace period at all, so foreign filing rights can be lost immediately on public disclosure). A TTO that learns about a disclosure only after it has already happened has a much narrower window to file a provisional application before rights are lost, particularly outside the U.S.
Illustrative filled-in example:
Prior public disclosure: None to date.
Planned disclosure: Manuscript to be submitted to [target journal] on or around September 2026; abstract already accepted for a conference poster session in October 2026.
Section 5: Funding and sponsor information
This section lists every source of funding that supported the work — federal grants and contracts (with award/grant numbers), foundation funding, industry-sponsored research agreements, and internal institutional funds. This field is what determines which body of law and which contractual obligations govern the invention: federal funding triggers Bayh-Dole “subject invention” status and the disclosure/reporting obligations described above (commonly tracked through iEdison, the interagency system many federal agencies use); industry-sponsored funding instead routes through whatever intellectual-property terms were negotiated in that specific sponsored research agreement, since Bayh-Dole does not apply to inventions made solely with private funds. Getting this section wrong — omitting a federal grant number, for instance — can create a real compliance gap discovered only much later, often during an audit or at the point of licensing.
Illustrative filled-in example:
Funding sources: NIH R01 [grant number], Meridian State University internal seed grant. No industry sponsor.
Section 6: Potential commercial applications and known related art
This section asks the inventors for their own view of who might use or license the technology, what market or product category it fits, and any competing patents, products, or publications they are already aware of. TTO staff will run their own prior art search regardless, but inventor-supplied leads — a competitor’s product name, a paper they read, a company that already approached them — often shortcut that search meaningfully and shape the initial commercial assessment.
Illustrative filled-in example:
Potential applications: Continuous glucose monitoring for Type 1 and Type 2 diabetes management; potential adjacent application in continuous lactate monitoring for athletic performance.
Known related work: [Competitor Company] Model X sensor (10-day wear); [cited published patent/application, if known].
Section 7: Confidentiality, certification, and signatures
The form closes with a certification that the information provided is accurate and complete to the best of the inventors’ knowledge, and each listed inventor signs and dates it. Most institutions also treat the disclosure itself as confidential once submitted — it is evaluated internally and is not made public unless and until a patent application is filed and published (typically 18 months after the earliest priority filing) or the technology is otherwise disclosed.
What happens after submission
Once a completed disclosure reaches the TTO, it typically moves through an internal triage step (assessing patentability, funding-source obligations, and rough commercial potential), a decision on whether to pursue patent protection (often starting with a provisional application to preserve an early filing date while evaluation continues), and, where federal funding is involved, the formal Bayh-Dole disclosure and election-of-title process. See CASRAI’s guides on patent application format and, for the federal-reporting side specifically, the interagency Edison invention-reporting process, for what comes next.
Frequently asked questions
Does submitting an invention disclosure form start the patent clock?
Not by itself — only an actual patent application filing does that. But the dates recorded on the form (conception, reduction to practice, any prior disclosure) are the evidence a TTO and patent counsel use to determine how much runway remains before a public disclosure or sale forecloses patent rights, so submitting it promptly matters even though it isn’t itself a filing.
Who should be listed as an inventor?
Only people who contributed to conceiving at least one claim of the eventual invention — a legal test, not a reward for who worked hardest on the project or whose name is on the related publication. Because authorship criteria (e.g., ICMJE) and inventorship criteria are different tests answering different questions, the author list on a paper and the inventor list on a disclosure frequently do not match exactly, and TTOs typically ask a patent attorney to confirm inventorship rather than leaving it to the research team alone.
What if the invention was already presented at a conference or posted as a preprint?
Disclose it anyway, and disclose it immediately — don’t wait to “clean up” the form. A prior public disclosure starts the one-year U.S. statutory grace period under 35 U.S.C. §102(b) and, in most other countries, may have already eliminated patent rights entirely (many jurisdictions have no grace period). The sooner the TTO knows the actual disclosure date, the more of that window remains to act.
Is the invention disclosure form itself confidential?
Institutional practice varies, but most TTOs treat it as an internal, confidential document while the invention is under evaluation, since public disclosure before a patent application is filed can itself create the same statutory-bar problem described above.
Does an invention disclosure form apply if the work wasn’t federally funded?
Yes — the internal disclosure-and-evaluation process is the same regardless of funding source. What changes is which body of law governs ownership and reporting afterward: federal funding brings Bayh-Dole obligations, while purely institutional or industry-sponsored funding is instead governed by the institution’s own IP policy and any sponsored research agreement terms.
