Congratulations to Janusz Liberkowski for Winning ABC's American Inventor

Janusz Liberkowski won one million dollars and the title as "ABC's First American Inventor". It is interesting to point out that of the four finalists, Janusz was the only inventor without a full working prototype. For all you inventors out there, it should be noted that for the purposes of filing a patent application in the United States Patent and Trademark Office, a working prototype is not required. To file a U.S. patent application, an enabling disclosure for an embodiment of the invention is required. Further, an invention is considered "reduced to practice" (constructively) as of the filing date of an application.
