What is an inventor's declaration?

An inventor’s declaration is a signed statement by the inventor confirming that the claims associated with a patent application are accurate and that the invention as described in the application was created entirely by them. It must be dated, signed and made under penalty of perjury and also include specific language as required by the US Patent and Trademark Office (USPTO). Inventors in Pennsylvania must specifically state that the application and its claims are all true to the best of their knowledge and that the invention was devised by them alone without any assistance. This declaration is a vital part of the patent process because it affirms to the USPTO that the application is true and accurate. Furthermore, if the inventor was assisted by any other individual in the creation of the invention, they must also be named in the declaration. Failing to do so could result in the patent being rejected or voided after it is granted.
