Proceedings overview
There are no AIA trial proceedings (IPR, PGR, CBM) on file for US Patent RE44742 as of 2026-06-01. This means the patent has not been challenged at the PTAB, which is an uncommon scenario for a patent that is actively asserted in litigation. Therefore, all claims of the patent remain untested at the PTAB.
Strategic summary
Currently, all claims of US patent RE44742 are UNTESTED at the PTAB. No IPR, PGR, or CBM proceedings have been filed against this patent. This implies that no claims have been canceled or found unpatentable through these administrative review processes.
The absence of PTAB activity means there is no estoppel landscape to consider under 35 U.S.C. § 315(e)(2) for potential petitioners. Any prior art grounds remain available for a defendant to assert in a new PTAB petition or district court litigation, assuming other statutory bars (like the one-year time bar for IPRs from service of a complaint) are not triggered.
The lack of PTAB challenges for RE44742 is notable, especially given its involvement in ongoing litigation (e.g., IOT Innovations LLC v. Schneider USA Inc, Case 2:26-cv-00334). This could indicate several things: either the asserted claims are perceived as robust, potential petitioners have not yet identified strong prior art, or strategic decisions have been made not to pursue PTAB challenges. However, it is also a signal that well-asserted patents often eventually attract IPRs.
Recommended next steps
As there is no PTAB activity on file for US Patent RE44742, a defendant facing assertion of this patent should consider the following:
- Conduct a thorough prior art search: Since no PTAB proceedings have occurred, the patent's validity against prior art has not been officially tested in this forum. A comprehensive prior art search could identify strong invalidity arguments under 35 U.S.C. §§ 102 and 103, which could form the basis for a new IPR or PGR petition.
- Evaluate IPR/PGR petition feasibility: If a strong prior art defense is identified, assess the viability of filing an IPR or PGR petition. This includes considering the one-year time bar for IPRs (from the date of service of a complaint alleging infringement) and whether the patent qualifies for PGR (filed within nine months of the reissue patent's issue date, which has passed for RE44742). The patent's reissue date was February 4, 2014, making it ineligible for a PGR petition.
- Monitor for future PTAB filings: Keep a close watch on the USPTO's Patent Trial and Appeal Case Tracking System (P-TACTS) (searchable via or the Open Data Portal) for any newly filed petitions against RE44742. Any such filing, especially if instituted, could significantly alter the defensive landscape.
