Guide · reviewed September 2026
Publication is a deadline.
The rule that surprises researchers most: your own publication can be used against your own patent application. Once the work is public, options narrow — in some countries, permanently.
What usually counts as a public disclosure
- Journal articles and accepted manuscripts
- Preprints and repository deposits
- Conference abstracts, posters, slides, and talks
- Public thesis submission or library release
- Demonstrations, trials, and pitches without confidentiality
- Product sales, quotations, and catalogue listings
- Detailed technical posts on social platforms and forums
- Open-source releases that reveal the technical contribution
What usually does not
- Discussion under a signed confidentiality agreement
- Internal lab meetings within your own organisation
- Confidential grant review, where the terms say so
- Private conversations with an advisor bound by professional duty
Disclosure rules and grace periods differ by country and change over time. Treat this as a prompt to check your specific position, not as legal advice.
- 01 List every fixed date: submission, abstract, poster, thesis, demo, launch
- 02 Identify the technical effect the work claims — in one sentence
- 03 Ask who owns it: you, your institution, your employer, your funder
- 04 Check whether anything has already been shown publicly, and when
- 05 Run at least a quick prior-art look before assuming novelty
- 06 Decide: file first, publish first, or protect a different way
- 07 If filing first, allow real time for drafting and inventor review
Already published? Options may still exist in some jurisdictions and they are time-bound. Bring the exact date of first disclosure — it changes the answer more than anything else you can tell us.
Questions
Common publication questions.
More in the FAQ.
In most systems, yes. A preprint server is a public disclosure with a date attached, and that date can be used against a later application.
An abstract that describes the technical contribution can be enough to count as a disclosure, even when the full paper comes later. Treat the abstract deadline as the real deadline.
It is a rescue, not a plan. Some jurisdictions provide a limited grace period for certain inventor disclosures; others do not. Relying on one usually costs you the countries that do not offer it.
