Patents. There are three requirements for specifications in a patent application they are called the enablement requirement, the best mode requirement and the written description requirement. By statute they require in respective order enough detailed information to enable one skilled in the art to make and use the claimed invention, disclosed the best way the inventor knows to make and use the invention, and shows that the inventor was in full possession of the claimed invention on the application's filing date. A failure to meet any of these requirements may result in rejection of the application. See 35 USCA § 112. Passing these tests at the patent office creates a presumption of adequacy of disclosure but that presumption is rebuttable by any challenger.
