What is a Disclosure Document and Its Importance in Patent Law?
Definition & Meaning
A disclosure document is a formal record that outlines an invention and is signed by the inventor or inventors. This document serves as proof of the date of conception of the invention and is submitted to the United States Patent and Trademark Office (PTO). It can be submitted by any inventor, a joint inventor, the owner of the invention, or their legal representative, such as an attorney or agent.
While a disclosure document is important, it is not the only way to establish the date of conception. Other acceptable forms of evidence include notarized records or laboratory notebooks that are permanently bound and page-numbered. Typically, a disclosure document is kept for two years and is destroyed afterward unless referenced in a related patent application within that timeframe. It is important to note that a disclosure document does not equate to a patent application.
