Proceedings overview
There are no AIA trial proceedings on file for U.S. Patent 7,670,612 B2. This means that all claims in the patent remain untested by the PTAB, and the patent's validity has not been challenged through an AIA trial.
Strategic summary
As of today, May 29, 2026, all claims of U.S. Patent 7,670,612 B2 are UNTESTED at the PTAB. There are no canceled, sustained, or pending challenges to any claims through an AIA trial proceeding.
The absence of PTAB activity means there is no estoppel landscape under § 315(e)(2) for any potential petitioner. All prior-art grounds remain available for challenge, subject to the statutory time bars for filing an IPR or PGR.
The lack of PTAB proceedings for this patent, especially given its publication date of March 2, 2010, is a noteworthy signal. Patents that are actively asserted or widely licensed often attract IPRs. The absence of such challenges could indicate a few possibilities: the patent may not have been broadly asserted, its claims might be perceived as robust, or potential challengers have opted for other defensive strategies.
Recommended next steps
Given that no PTAB activity exists for U.S. Patent 7,670,612 B2, a defendant facing assertion of this patent would need to conduct their own prior art search and validity analysis. If a challenge is deemed viable, an Inter Partes Review (IPR) or Post-Grant Review (PGR), depending on the specific circumstances and filing date of the patent's original application, could be considered. However, the window for PGR has closed as it must be filed within 9 months of the patent's grant. An IPR can be filed any time after the later of 9 months after grant or the termination of any PGR, provided the petitioner is not time-barred.
