What is the significance of the effective filing date in determining prior art under AIA?
The effective filing date is crucial in determining what constitutes prior art under the America Invents Act (AIA). According to MPEP 2155.02, the effective filing date serves as a critical reference point for assessing whether a disclosure qualifies as prior art.
The MPEP states: “If the subject matter disclosed had, before such subject matter was effectively filed under 35 U.S.C. 102(a)(2), been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor, the subject matter disclosed under 35 U.S.C. 102(a)(2) shall not be prior art to the claimed invention under 35 U.S.C. 102(a)(2).“
This means:
- Disclosures made before the effective filing date of the claimed invention may be considered prior art.
- However, if the inventor publicly disclosed the subject matter before the effective filing date of a potential prior art reference, that reference may be disqualified as prior art.
- The effective filing date helps determine the order and relevance of disclosures in the patentability assessment.
Understanding the effective filing date is essential for both inventors and patent examiners in evaluating the novelty and non-obviousness of an invention under the AIA system.
