One of the provisions of the new patent law reform bill (HR1249) that has recently taken effect is a change to the requirement that the original inventor sign the patent application. January 27, 2012

The America Invents Act (AIA), recently signed into law, made a number of updates to US patent law. HR 1249: America Invents Act">change to patent law that took immediate effect: the longstanding policy that the original inventor must sign the patent application has been changed to allow an assignee with sufficient proprietary interest the right to file a patent application without the inventor’s signature[35 U.S.C. §118]. This change brings US patent law more in line with patent laws in most other nations.

“From the inception of US patent laws, is has been a fundamental tenet that only the true and original inventor can file an application by signing an oath attesting to inventorship,” explains Malcolm Wittenberg, an intellectual property attorney at Bay Area Technology Law group. He explains that 35 U.S.C. §115 calls for the oath being made by the applicant asserting that he believes himself to be the original and first inventor of the subject being claimed.

The previously existing US patent law did provide for the filing of a patent application without the inventor’s signature, but only in a few instances: in the event of death or incapacity [35 U.S.C. §117], when an inventor refuses to execute an application, or when the inventor cannot be found or reached after diligent effort [35 U.S.C. §118]. Despite these exceptions, Wittenberg points out, the procedure to file an application without the signature of the inventor has been a difficult and time-consuming process.

As noted in 37 C.F.R §1.47, if an inventor refuses to join in an application for patent or cannot be found or reached, the entity filing the application must prove that a diligent effort was made to procure the appropriate signature, a petition must be filed including proof of the pertinent facts, the payment of the fee and an indication of the last known address of the non-signing inventor. The petition must also include a showing that the filing of the application without the inventor’s signature is necessary to preserve the rights of the parties or prevent irreparable damage.
