Public disclosure

A public disclosure is any non-confidential communication which an inventor or invention owner makes to one or more members of the public, revealing the existence of the invention and enabling an appropriately experienced individual ("person having ordinary skill in the art") to reproduce the invention. A public disclosure may be any form of non-confidential communication. For example an academic poster, presentation to a symposium/conference, website article, book chapter, academic journal article, or even an unguarded conversation in a car park.
