There are commentators who believe that inventors would benefit from publicly disclosing prior to filing a patent application, based on the “exception” provision under new law of 35 USC 102. However, as a practical matter, it is very risky to publicly disclose prior to a filing of a patent application primarily for the following reason: There is always room for improvements on the original invention. If the inventor discloses the original invention, and a competitor sees it and improves on it and file a patent application on the improved version, then most likely the “exception” clause under 35 USC 102 will not apply and the inventor will lose out.
