Is there name of all inventors on a Patent application?
yes, a company lists the names of all inventors for a patent for which they submitted an application. No, signatures of the inventors, if they are employees, are not required. Normally, a company makes an employee sign a waiver, granting all rights to inventions and discoveries made during the course of employment. The employee is still the inventor, but does not own the patent. The USPTO has an extensive search engine, where you can search for pending applications. However, the database only includes data on Published Applications in accordance with the 18 month pre-grant publication rules. Pending patent applications where the applicant has elected to not publish prior to grant remain confidential.
