Patent Prosecution is the process of applying for and obtaining a patent. Patent prosecution should not be confused with "patent litigation," which is the term used to describe the process of protecting a patent from infringement.

A Patent is a property right granted by the United States Government. When an inventor owns a patent to his invention, he is able to exclude others from making, using, offering for sale, or selling the invention in the US.

Who Can File an Application for Patent Prosecution?

Only the actual inventor can file for a patent. However, if the inventor is dead or legally insane, his legal representatives can submit an application.

Patent attorneys and patent agents are registered with the PTO to prepare, file, and prosecute patents in the name of their client.
