PTAB challenges

Proceedings overview

As of June 9, 2026, there are no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method) on file for US Patent 8,031,654 in the USPTO's Open Data Portal, nor have recent web searches revealed any unindexed proceedings. This means that all claims of US8031654 remain untested by the PTAB. This presents a defendant with the opportunity to be the first to challenge the patent's validity before the PTAB.

Strategic summary

Currently, all claims of US8031654 (claims 1-24) are UNTESTED by the PTAB. No claims have been canceled or sustained through an AIA trial proceeding.

The estoppel landscape for any potential petitioner is entirely open, as no prior art grounds have been adjudicated or barred under 35 U.S.C. § 315(e)(2). A defendant facing assertion of this patent today would have full latitude to present any valid prior art challenges in an IPR, PGR, or CBM petition.

There are no observable patterns of repeated PTAB filings by a single petitioner or aggressive PTAB appeals by the patent owner, as no proceedings exist. The current assignee, Integral Wireless Technologies LLC, is noted to be involved in ongoing litigation in various district courts as of October 2024, as indicated in the Google Patents record. The absence of PTAB challenges for an actively litigated patent could be an indicator that previous demand letters or assertions did not lead to IPR filings, or that the patent has not been extensively challenged by major operating companies who typically leverage PTAB proceedings.

Recommended next steps

If you are a defendant facing an assertion of US Patent 8,031,654, the recommended next steps are:

• Conduct a thorough prior art search: Since the patent has not been subjected to PTAB review, a comprehensive search for invalidating prior art is critical. This should focus on the asserted claims and identify potential grounds for unpatentability under 35 U.S.C. §§ 102 and 103.
• Evaluate potential IPR/PGR/CBM petitions: Based on the prior art search, assess the viability of filing an AIA trial petition (likely an IPR given the patent's age and subject matter). A successful petition could invalidate asserted claims and significantly strengthen your defensive posture.
• Monitor for future PTAB activity: Keep a close watch on the USPTO PTAB E2E system for any newly filed petitions related to US8031654, as any party facing assertion might initiate a challenge.
• Consider a pre-institution challenge analysis: Engage experienced PTAB counsel to evaluate the strength of potential invalidity arguments and strategize the optimal approach, including claim construction considerations and potential expert declarations.## Proceedings overview

The estoppel landscape for any potential petitioner is entirely open, as no prior art grounds have been adjudicated or barred under 35 U.S.C. § 315(e)(2). For a defendant currently being asserted against, this means there is full latitude to present any valid prior art challenges in an IPR, PGR, or CBM petition.

There are no observable patterns of repeated PTAB filings by a single petitioner or aggressive PTAB appeals by the patent owner, as no proceedings exist. The current assignee, Integral Wireless Technologies LLC, is noted to be involved in ongoing litigation in various district courts, as indicated in the Google Patents record. The absence of PTAB challenges for an actively litigated patent could suggest that previous demand letters or assertions did not lead to IPR filings, or that the patent has not yet been extensively challenged by parties who commonly use PTAB proceedings.

Recommended next steps

If you are a defendant facing an assertion of US Patent 8,031,654, the recommended next steps are:

• Conduct a thorough prior art search: Since the patent has not been subjected to PTAB review, a comprehensive search for invalidating prior art is critical. This search should focus on the asserted claims and identify potential grounds for unpatentability under 35 U.S.C. §§ 102 and 103.
• Evaluate potential IPR/PGR/CBM petitions: Based on the prior art search, assess the viability and strategic benefit of filing an AIA trial petition (likely an IPR, given the patent's issue date of October 4, 2011, which falls outside the PGR window). A successful petition could invalidate asserted claims and significantly strengthen your defensive posture.
• Monitor for future PTAB activity: Keep a close watch on the USPTO PTAB E2E system for any newly filed petitions related to US8031654, as any party facing assertion might initiate a challenge. Information on searching PTAB decisions and proceedings is available on the USPTO website.
• Consider a pre-institution challenge analysis: Engage experienced PTAB counsel to evaluate the strength of potential invalidity arguments and strategize the optimal approach, including claim construction considerations and potential expert declarations.
