The inventor should consider commissioning a preliminary patentability search prior to applying for a patent. A search will provide information concerning whether the invention is patentably distinct from inventions already patented (“prior art”). While preliminary patentability search is not a prerequisite to filling a patent application, it is highly advisable to ensure the proper scope of the patent application and the validity of the potential patent. Lott & Fischer offers a fixed-rate patentability search and opinion letter. Send email to email@example.com to immediately obtain the most up-to-date fee schedule.
