Strategic summary
As of July 7, 2026, there are no AIA trial proceedings (IPR, PGR, or CBM) that have challenged the validity of claims in US Patent 8064202. This means that all claims of US8064202 remain UNTESTED in the context of PTAB validity challenges.
The absence of PTAB activity suggests that the patent has not been subjected to the rigorous, accelerated validity reviews offered by these proceedings. For a potential defendant facing assertion of this patent, this implies that the patent claims have not been affirmed as patentable by the PTAB, nor have they been invalidated. Consequently, the estoppel provisions of 35 U.S.C. § 315(e)(2) do not apply, leaving all prior-art grounds open for a future petitioner to raise in an IPR or PGR, assuming statutory timing and standing requirements are met.
Recommended next steps
If you are a defendant facing assertion of US Patent 8064202 today, the primary observation is that there is no PTAB activity. This means:
- No claims have been invalidated or confirmed by the PTAB. All claims of US8064202 are untested in this forum.
- All prior art grounds are theoretically available. You are not estopped by any prior PTAB proceeding from raising any ground of invalidity under 35 U.S.C. §§ 102 or 103 (for IPR) or additional grounds under § 112 or § 101 (for PGR/CBM, if applicable and within time limits).
- Consider filing your own PTAB petition. The absence of prior PTAB challenges means that a new petitioner would be the first to test the patent's validity before the Board. This might be a viable defensive strategy, potentially offering a faster and less expensive route to challenge validity compared to district court litigation.
