What are the requirements for a patent to be granted?

In Washington, the requirements for a patent to be granted are stringent. To be granted a patent, an invention must be new, useful, and non-obvious. The invention must be new, meaning it cannot be available to the public before the patent is filed. Additionally, the invention must not have been previously described in a printed publication, used publicly, or sold in the United States or a foreign country. The invention must be useful, meaning it must have a useful purpose or provide a useful result. It may not be a frivolous or a purely theoretical invention. The invention must be non-obvious, meaning that it cannot be an invention that would be obvious to a person of ordinary skill in the relevant field. The idea must be a significant advance from what currently exists in the field. Finally, a patent application must include a written description and drawings of the invention, as well as a claim that defines the boundaries of the invention and protects it from being copied or used without permission. The application must be filed with the United States Patent and Trademark Office. If these criteria are met, the application will be reviewed by a patent examiner and, if approved, a patent will be granted. This patent will then provide the inventor with exclusive rights to the invention for a certain amount of time.
