A new inter partes review has been filed at the Patent Trial and Appeal Board against ResMed Corp., opening another front in the increasingly important fight over respiratory and sleep-therapy technology. The petition, docketed as IPR2026-00341 and filed June 12, 2026, places at issue the validity of a ResMed patent before the PTAB, where petitioners can seek cancellation of issued patent claims based on prior art patents and printed publications.

At this early stage, the publicly available docket information identifies the proceeding as Resmed Corp., but does not yet provide the full set of petition details typically most relevant to practitioners, including the patent number, the petitioner’s identity, and the specific prior-art combinations asserted.

Another PTAB proceeding has been filed against ResMed, with IPR2026-00341 entering the Patent Trial and Appeal Board on June 12, 2026. The petition places one of ResMed’s patents under inter partes review, opening a new front in what could become an important dispute for companies operating in the sleep-disorder and respiratory-device space.

At this stage, the publicly available docket identifies the proceeding by the title Resmed Corp., but practitioners will want to monitor the case record closely as the petition, mandatory notices, and related filings further clarify the specific patent claims at issue, the identity of all real parties in interest, and any parallel district court or ITC litigation that may shape the Board’s discretionary-review analysis.

As with any newly filed IPR, the key issues will center on which patent is being challenged, which claims are targeted, and what prior-art grounds are asserted. Typically, petitioners rely on anticipation and obviousness grounds under 35 U.S.C. §§ 102 and 103, supported by combinations of patents, printed publications, and expert declarations.
