Patent Law FAQ
This FAQ answers all your questions about patent law, patent procedure, and the patent examination process.
Here’s the complete FAQ:
March 16, 2013 is a crucial date in U.S. patent law due to the implementation of the America Invents Act (AIA). This date marks the transition from the pre-AIA first-to-invent system to the AIA first-inventor-to-file system. The significance includes:
- Applications filed on or after this date are generally subject to AIA provisions
- The effective filing date of claimed inventions determines which law applies
- Transition applications may require special statements
- Different examination standards may apply based on the effective filing date
The MPEP states: “The first inventor to file provisions of Public Law 112-29, sec. 3, 125 Stat. 284 (the Leahy-Smith America Invents Act) and the rules related thereto became effective March 16, 2013. These provisions apply to any application for patent, and to any patent issuing thereon, that contains or contained at any time— (A) a claim to a claimed invention that has an effective filing date as defined under section 100(i) of title 35, United States Code, that is on or after March 16, 2013; or (B) a specific reference under section 120, 121, or 365(c) of title 35, United States Code, to any patent or application that contains or contained at any time such a claim.”
