WHAT IS NOT PATENTABLE
An inventor cannot receive a patent for perpetual motion devices, abstract ideas, laws of nature, and naturally occurring substances. An inventor cannot receive a United States patent for an invention publicly disclosed more than 12 months ago.
Public disclosure includes any sale, exhibit at trade show, or printed in a publication, with a few exceptions. You should seek a Patent Attorney’s opinion if you have any questions whether your invention is patentable. It should also be noted that you do not need a prototype when seeking patent protection – you only need to be able to describe the invention in sufficient detail so that one skilled in the art could construct your invention.
