The Patent Trademark Office carefully reviews the application in order to determine the invention’s patentability. Upon submission of a patent application to the Patent Trademark Office an Examiner reviews the application and prepares an opinion as to whether the application complies with the Patent Trademark Office applicable rules and regulations, and whether the invention is indeed “patentable.”

The patent cost can be very high for some people which the U.S. Patent Trademark Office charges a minimum of about $4,000 over the life of the patent. A patent application submitted to Patent Trademark Office must contain: (1) a written description of the invention; and (2) claims particularly pointing out and distinctly claiming the invention.

Patent database is a collection of information pertaining to patents. It is always good to refer to do patent search in a patent database before investing thousands of dollars in patent application. This way inventors can save money if during the search in patent database they found out that the invention is a ‘prior art’. All is not lost for the inventor though if that happens because he or she can always claims certain elements of the proposed invention to be patentable.
