What is a Statutory Invention Registration (SIR)?
A Statutory Invention Registration (SIR) is a defensive publication that provides some of the benefits of a patent without granting enforceable rights. As stated in the MPEP, A statutory invention registration is not a patent. It has the defensive attributes of a patent but does not have the enforceable attributes of a patent.
SIRs are published and can be used as prior art, but they do not grant the holder the right to exclude others from making, using, or selling the invention.
