PTAB challenges

Proceedings overview

A search for AIA trial proceedings related to US Patent 9207748, including through web searches for IPR, PGR, and CBM cases, did not yield any records of such proceedings. The USPTO Open Data Portal (ODP) also indicates no AIA trial proceedings on file for this patent.

Since there are no PTAB proceedings on file, the defensive posture for a defendant facing assertion of this patent is that all claims (1-20) remain untested by PTAB challenges.

Strategic summary

As of today, May 25, 2026, all twenty claims of US Patent 9207748 remain untested by inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) patent proceedings at the Patent Trial and Appeal Board (PTAB). There are no records of any challenges to the patentability of these claims through the AIA trial processes. This means there is no estoppel landscape established by PTAB decisions. Any prior art grounds potentially relevant to this patent (e.g., under 35 U.S.C. §§ 102 or 103) are still available for a defendant to raise in a new PTAB petition or district court litigation.

The absence of PTAB activity is notable, especially given the patent's original assignee, Intellectual Ventures I LLC, and its current assignee, Integral Wireless Technologies LLC, both of which have been involved in patent monetization activities. Patents that are actively asserted often become targets for IPRs, making the lack of such proceedings for US9207748 an unusual signal.

Recommended next steps

Since no PTAB activity exists for US Patent 9207748, a potential defendant facing assertion of this patent would have the full range of prior art arguments available to them.

• Consider filing a new PTAB petition: If facing an assertion, a defendant could consider filing an IPR petition against claims 1-20, or a subset thereof, based on relevant prior art. This would be a first opportunity to challenge the patent's validity before the PTAB.
• Prior art search: Conduct a thorough prior art search to identify strong invalidity grounds under 35 U.S.C. §§ 102 and 103, particularly focusing on the "wireless device wake-up process" and "power-save and non-power-save modes" aspects of the claims.
• Monitor for future filings: Continuously monitor the PTAB E2E system for any newly filed petitions against US9207748, as the absence of past challenges does not preclude future ones.

The current lack of PTAB activity suggests that the patent's claims have not yet been rigorously vetted through the AIA trial process, which could represent an opportunity for a defendant.
