What is the significance of the March 16, 2013 date in patent law?
March 16, 2013, is a crucial date in U.S. patent law as it marks the implementation of the America Invents Act (AIA), which significantly changed the patent system. The MPEP highlights this date’s importance:
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA.
Key changes that took effect on this date include:
- Transition from a “first-to-invent” to a “first-inventor-to-file” system
- Modifications to what constitutes prior art under 35 U.S.C. 102
- Changes in how priority and effective filing dates are determined
Applications filed before March 16, 2013, are generally examined under the pre-AIA provisions, while those filed on or after this date are typically subject to AIA provisions. However, some exceptions exist for applications with claims having an effective filing date before March 16, 2013.
Understanding whether your application falls under AIA or pre-AIA provisions is crucial for determining applicable prior art and available patent strategies.
