Patent Application
The formal document filed with a patent office requesting the grant of a patent on an invention.
What It Means
A patent application is the starting point of the patent prosecution process. It is a legal document filed with the USPTO (or another national patent office) that describes the invention in full detail and requests the grant of exclusive rights. A complete utility patent application includes several components: the specification (a written description of the invention), claims (the legal boundaries of what the patent covers), an abstract, and usually drawings. The application must demonstrate that the invention is novel, non-obvious, and useful. Once filed, the application is assigned to a patent examiner who reviews it against prior art, existing patents, publications, and public knowledge. The filing date is critically important because it establishes priority and determines the patent term. The application is typically published 18 months after filing, making the technical disclosure public even before the patent is granted. The average time from filing to grant in the U.S. is approximately 23 months, though this varies widely by technology area. Patent applications in complex fields like biotechnology or software can take 3-5 years to be examined. Filing fees, attorney costs, and prosecution expenses mean that a typical U.S. patent application costs between $10,000 and $30,000 from filing through grant.
