What is an inventor's declaration?

An inventor’s declaration is a document that is used when filing for a patent. It is a statement by the inventor that the invention is new, useful, and was not previously known or used by others. This declaration is usually signed by the inventor in front of a notary and filed with the patent application. In California, the patent application requires an inventor’s declaration. This declaration is used to verify that the inventor is the sole creator of the invention and that the invention has not been previously patented or described in the prior art. The declaration must be signed by the inventor, under oath, and affirmed to be true. In addition to the inventor’s declaration, an oath or declaration form must also be completed by the inventor. The oath or declaration is a statement of facts about the invention that further proves the invention is new and not known or used by others. This form must be signed and dated by the inventor and must include the inventor’s name, address, and residence. The inventor’s declaration is an important step when filing for a patent in California. It helps to ensure that the invention is new and that the inventor is the sole creator of the invention. The declaration must be signed and verified by an authorized officer.
