Do I really need a Patent Attorney?

The success rate of inventors attempting to file their own patent applications is very low compared to the success in obtaining meaningful patent protection using an experienced patent lawyer. The reason being is that there are hundreds of pages of laws, rules, and interpretations, as well as a specific vocabulary covering the writing of a patent application that must be learned before writing a patent application. A rule or law can change overnight by the Supreme Court or by the U.S. Patent Office (USPTO). Patent attorneys are the only attorneys who must have a technical degree and then pass both a state and a federal patent bar exam before being allowed to practice patent law before the USPTO, before writing/prosecuting patent applications, before giving patentability opinions, and the like.  Therefore, unless you plan on studying patent law for a couple of years and before attempting to execute a process fraught with traps, complexities, and difficulties, it would be best to consult an expert, i.e., an experienced patent attorney (someone with at least 10 years of experience).
