Invention Disclosure Form: What It Is and How to Complete One
An invention disclosure form is the formal starting point for any IP protection process. It captures what was invented, who invented it, and when — and triggers the evaluation and protection decisions that follow. Here is everything you need to know.
Key Takeaway
An invention disclosure form does three critical things: it establishes the date of invention, creates a formal record of who invented what, and provides the technical foundation for a patent application or trade secret programme. Pairing it with a blockchain timestamp makes that record immutable, court-ready, and independently verifiable — at a cost of £10-50.
In This Guide
Every major patent filed by a university, hospital, or corporate research lab began with an invention disclosure form. It is the trigger document: the moment an inventor formally says “I have created something new, and here is what it is.”
Without a disclosure form — or something equivalent — IP decisions happen ad hoc, ownership is disputed, and inventions are lost to competitors or public domain. The disclosure form is the foundation of any serious IP management programme.
1. What Is an Invention Disclosure Form?
An invention disclosure form (IDF) is a structured document completed by an inventor to formally record a new invention and submit it for IP evaluation. It is the starting point for the entire patent or IP protection process.
The form captures the essential details that legal and technology transfer teams need to make three decisions: whether the invention is patentable, whether to pursue a patent or trade secret strategy, and who owns the IP based on employment and funding arrangements.
The disclosure form triggers these decisions:
2. Who Uses Invention Disclosure Forms?
Universities and research institutions
Disclosures are submitted to the Technology Transfer Office (TTO), which evaluates commercial potential and manages patent filing. Most universities require researchers to disclose inventions before publication.
Corporate R&D departments
Large organisations use IDFs to systematically capture inventions from engineering and research teams. They trigger the patent review process and ensure IP ownership is formally documented.
Startups and SMEs
Earlier-stage companies use simplified disclosure forms to document inventions before pursuing formal IP protection. This creates a timestamped record even if patent filing is deferred.
Government research labs
Public sector research organisations are often required to formally disclose inventions created with public funding, particularly for Bayh-Dole compliance in the US.
Hospital and medical research teams
Clinical and medical device inventions are disclosed before publication to protect patentability. Publication before disclosure can destroy novelty.
Individual inventors
Solo inventors can use a personal invention disclosure as a structured way to document their invention before sharing with anyone or filing any formal application.
Important: disclose before you publish
In most jurisdictions, any public disclosure of your invention before filing a patent application destroys novelty and makes the invention unpatentable. “Public disclosure” includes academic papers, conference presentations, social media posts, and demos. Submit your invention disclosure form and get a patent filing decision before any public communication.
3. What to Include in an Invention Disclosure Form
A comprehensive invention disclosure form covers these areas. The more detail you provide, the better the IP evaluation will be:
A. Inventor Information
- Full name and contact details of each inventor
- Employment or affiliation at time of invention
- Each inventor's contribution to the invention
- Prior agreements (NDAs, confidentiality, assignment agreements)
B. Invention Description
- Title of the invention
- Summary of what the invention does and what problem it solves
- Detailed technical description of how it works
- Preferred embodiment (the best way to implement it)
- Alternative implementations or variations
- Diagrams, drawings, flowcharts, or schematics
C. Novelty and Prior Art
- What existing solutions are available? How does this invention differ?
- Results of any prior art searches conducted
- Known related patents, publications, or products
- What is the key inventive step over existing solutions?
D. Development History
- When was the invention first conceived?
- Key dates in the development timeline
- First working prototype or proof of concept date
- First public use or demonstration (if any)
E. Public Disclosures
- Has the invention been publicly disclosed in any form?
- Conference presentations, papers submitted, demos given
- Any planned publications or presentations
- Grant applications that describe the invention
F. Funding and Ownership
- What funding sources supported this work?
- Any government grants (especially for Bayh-Dole compliance in the US)
- Industry sponsor agreements that may affect ownership
- Any pre-existing IP that the invention builds upon
G. Commercial Potential
- Target markets and industries
- Estimated market size
- Known companies that might be interested in licensing
- Potential for company spinout

5. What Happens After You Submit an Invention Disclosure?
The process after submission varies by organisation, but typically follows this flow:
Acknowledgement
The receiving party (TTO, legal team, or IP manager) acknowledges receipt and assigns a reference number. This creates the formal record.
Initial assessment (1-4 weeks)
A preliminary evaluation of novelty, patentability, and commercial potential. The team may ask follow-up questions or request clarification.
Prior art search (2-6 weeks)
A formal prior art search by a patent professional to assess novelty. Results determine whether to proceed with a patent application.
IP decision
A decision is made: file a patent application, protect as a trade secret, publish strategically (to create defensive prior art), or do nothing.
Patent filing (if applicable)
If patenting: work begins on drafting the application. In the UK, a complete patent can take 2-5 years to grant. The filing date establishes priority.

6. How Blockchain Timestamps Strengthen Your Invention Disclosure
A paper or digital invention disclosure form is only as secure as the system it is stored in. Documents can be altered, backdated, or disputed. A blockchain timestamp changes this fundamentally — by creating an immutable, independently verifiable record of your disclosure content and date.
Immutable record of invention date
When you blockchain-timestamp your completed invention disclosure form, you create proof that the specific document — with all its technical details — existed at a precise moment. This cannot be altered, backdated, or disputed. It is permanently recorded on the public XRPL blockchain.
Protection before the TTO acts
University TTOs can take weeks or months to evaluate a disclosure. During that period, your invention is at risk — from independent discovery, from colleagues who know about your work, or from inadvertent disclosure. A blockchain timestamp at the moment of disclosure protects your priority date regardless of how long the evaluation takes.
Evidence of prior invention in disputes
If another party claims they invented the same thing first, your blockchain-timestamped disclosure is court-ready evidence of your priority date. Courts accept blockchain records as evidence in UK, US, and EU jurisdictions.
Supports patent applications
A timestamped disclosure strengthens the supporting evidence for a patent application. If the patent is challenged on priority date grounds, the timestamp provides independent corroboration of when the invention was documented.

Frequently Asked Questions
What is an invention disclosure form?
An invention disclosure form is a structured document completed by an inventor to formally record a new invention and submit it for IP evaluation. It captures what was invented, who invented it, when, and how it works. It is the starting point for patent decisions, trade secret programmes, and IP ownership determinations.
Do I need an invention disclosure form if I am an individual inventor?
If you are an employee or contractor, you likely have an obligation to disclose inventions to your employer — the form formalises this. As a solo inventor, a formal disclosure creates a timestamped record of your invention even if you file your own patent. It is good practice regardless of your situation.
What is the difference between an invention disclosure and a patent application?
An invention disclosure is an internal document that captures the invention and triggers the evaluation process. A patent application is the formal legal submission to a patent office that, if granted, gives you exclusive rights. An invention disclosure often precedes a patent application and provides the technical detail that the patent application builds on.
Can I publish my research before submitting an invention disclosure?
Publishing before disclosing the invention to your TTO or IP team — and before any patent is filed — may destroy patentability by creating prior art. In the US, there is a one-year grace period for the inventor's own disclosure. In the UK and EU, there is no grace period — publication before filing is usually fatal to patentability. Always disclose to your TTO before publishing or presenting.
How does immut help with invention disclosure?
immut provides blockchain timestamping of your invention disclosure documents. When you upload your completed disclosure form, immut generates a cryptographic hash of the documents and records it permanently on the XRPL blockchain. This creates immutable proof that your specific invention documentation existed at a precise date — independently verifiable by any court or patent office.
