Most inventors hope to either actively participate in the commercialization of their invention or license the invention so they may receive a royalty for such commercialization efforts. Working with a patent attorney to seek patent protection is only a portion of the typical patent based business.
Inventors have the right to prepare and file a patent application without the assistance of a patent lawyer. Inventors have always had this right, referred to as prosecuting a patent pro se, which is described in the Code of Federal Regulations (37 CFR 1.31) and in the Manual of Patent Examination Procedure (section 401). Well-funded organizations rarely seek patent protection without the assistance of a lawyer.
