Statutory Invention Registration (SIR) is a document relating to an invention published by the U.S. Patent and Trademark Office (USPTO). However, SIR is not considered a patent. An applicant (inventor) is required to meet the following conditions to have a patent application published:
1.The application should comply with the requirements for printing, as set forth in regulations of the director of the patent office;
2.The applicant waives the right to receive a patent on the invention within such period as may be prescribed by the director; and
3.The applicant must pay application, publication, and other processing fees established by the director.
Additionally, pursuant to 35 USCS § 112, an application must contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and should also set forth the best mode contemplated by the inventor in carrying out his/her invention.
SIR is published in the official gazette and can be utilized by an examiner as a prior art reference. Because the invention is made public, no one can be granted a patent for that invention. There are no patent rights accorded to SIR.
