Are Statutory Invention Registrations (SIRs) still accepted by the USPTO?
No, Statutory Invention Registrations (SIRs) are no longer accepted by the USPTO. According to MPEP 901.06(d):
“However, requests for a statutory invention registration filed on or after March 16, 2013 will not be processed, as the provisions of pre-AIA 35 U.S.C. 157 governing Statutory Invention Registrations were repealed.”
This change was part of the America Invents Act (AIA) reforms. Inventors seeking to disclose their inventions without pursuing a full patent should consult with a patent attorney to explore alternative strategies, such as defensive publication through other means or considering provisional patent applications.
