The Patent Reform Act of 2011 ("S.23") is now being considered by the full U.S. Senate. One of the provisions of S.23 would replace the current first-to-invent ("FTI") system with a first-inventor-to-file ("FITF") system. Some of the differences between these two systems are outlined below in order to help understand the changes in Sec. 2 of the S.23 Bill. For simplified illustrative purposes, Parties ("A" and "B") and their invention ("Widget") will be used below.

First-to-Invent

The current U.S. system is a first-to-invent ("FTI") system. Under the FTI system, the first party to invent is entitled a patent on that invention upon filing for a patent application (as long as all of the other patentability requirements are met). Even if the first party to invent is not the first to file, that party could still be entitled to the patent rights. In situations where there are multiple inventors of the same invention, the determination as to who is entitled to the patent rights is made during an interference proceeding. Interference proceedings are administrative proceedings held at the USPTO that legally determine the first inventor. However, there are time constraints on interference proceedings, e.g., typically a party cannot bring an interference proceeding on an invention after a patent has issued on that patent. Therefore, the first person to file would get the patent unless another person is able to prove prior invention in an interference proceeding.

The following examples involve two parties who claim the same invention in an FTI system:
