ResMed v. Cleveland Medical Devices: Patent Case Transferred to N.D. Ohio
ResMed Co. filed suit against Cleveland Medical Devices Inc. in the Southern District of California asserting US11602284B1, covering devices and methods for sleep disorder diagnosis and treatment. After 239 days, the district court ordered the case transferred to the Northern District of Ohio, Eastern Division, where proceedings continue.
Sleep tech patent dispute leaves California, heads to Ohio
On 20 March 2023, ResMed Co. filed an infringement action against Cleveland Medical Devices Inc. in the United States District Court for the Southern District of California, asserting US11602284B1 — a patent directed to devices and methods for sleep disorder diagnosis and treatment. DLA Piper US LLP represented ResMed; Kramer Levin Naftalis & Frankel LLP appeared for Cleveland Medical Devices.
The case did not reach a merits ruling in California. The Southern District of California court ordered the case transferred to the Northern District of Ohio, Eastern Division, with files transmitted electronically to the federal courthouse at 801 West Superior Avenue, Cleveland, OH 44113. The recorded basis of termination is 'Case Transferred'; no settlement, dismissal, or judgment is recorded in the available public record.
The transfer was completed within 239 days of filing, a timeline consistent with a venue dispute resolved at a relatively early procedural stage. Whether the transfer was ordered on the defendant's motion, the court's own initiative, or by stipulation is not disclosed in the available record. The substantive infringement claims remain unresolved and will be litigated in the Northern District of Ohio.

US11602284B1 — Devices and Methods for Sleep Disorder Diagnosis and Treatment
Any company designing, manufacturing, or selling devices or methods for sleep disorder diagnosis and treatment should assess potential exposure to US11602284B1. With active litigation now proceeding in the Northern District of Ohio, the claim scope remains legally unsettled — which means freedom-to-operate risk is currently unquantified. R&D and product teams working on sleep monitoring hardware, home sleep test devices, or diagnostic software should flag this patent for review before committing to product designs that could intersect with its claims.
Official order — verbatim text
The docket order records a straightforward venue transfer to the Northern District of Ohio, Eastern Division, with files transmitted electronically. No merits determination accompanies this disposition — the transfer resolves only the question of forum, leaving all infringement and validity issues under US11602284B1 to be litigated anew before the receiving court.
Case transferred to N.D. Ohio: what the venue change means for both parties
What a federal case transfer means procedurally
A case transfer under 28 U.S.C. § 1404(a) or § 1406(a) moves the entire action — pleadings, evidence, and procedural history — to a new district court. The transferring court makes no ruling on the merits. All substantive claims, including infringement and any defences, are re-opened before the receiving court, which applies its own local rules and scheduling. No finding of liability or non-liability accompanies the transfer.
No merits rulingResMed must now litigate in Cleveland's home court
For ResMed, the transfer means pursuing its US11602284B1 infringement claims before the Northern District of Ohio rather than its preferred Southern District of California forum. Litigation in a new district typically requires local counsel, familiarity with a different judge's practices, and potential scheduling delays while the receiving court integrates the case. The infringement claims themselves remain fully intact.
Forum shift for plaintiffCleveland Medical Devices litigates closer to home
For Cleveland Medical Devices, headquartered in Ohio, the transfer to the Northern District of Ohio, Eastern Division represents a significant procedural advantage: the case now sits in the defendant's home jurisdiction. Access to local witnesses, records, and infrastructure is typically easier in the transferee district. However, the defendant still faces the substantive infringement allegations under US11602284B1, which are unresolved.
Home-court advantage for defendantVenue shapes litigation economics in medical device disputes
Venue transfers in patent cases can materially affect litigation cost, duration, and settlement dynamics. The Northern District of Ohio carries its own patent case statistics, judicial temperament, and median time-to-trial that differ from S.D. Cal. Companies in the sleep-tech and medical-device sector should monitor whether ResMed's US11602284B1 claims are ultimately upheld, narrowed, or invalidated in Ohio, as the outcome will affect freedom-to-operate assessments across the segment.

ResMed's patent activity in sleep diagnostics and therapy
ResMed's willingness to assert US11602284B1 — a recently issued patent — suggests active and ongoing prosecution in the sleep disorder technology domain. Mapping ResMed's broader filing activity can reveal where the company is building claim coverage around diagnosis, monitoring, and therapy delivery, and where competitors may face growing IP barriers.
ResMed filing trendsFiling trends in sleep disorder diagnosis and treatment technology
The sleep-health sector is seeing increased patent activity spanning hardware sensors, AI-driven diagnostics, and therapy delivery systems. Understanding where filing density is highest — and where gaps remain — is essential for R&D teams planning next-generation sleep monitoring or treatment products that must navigate existing IP.
Sleep-tech IP densityCleveland Medical Devices' patent position in sleep health
As the defendant in an infringement action, Cleveland Medical Devices' own patent portfolio and R&D activity merit scrutiny. Understanding their filing history, technology focus areas, and any defensive patents in sleep diagnostics can inform both litigation strategy and competitive intelligence for others in the sector.

What this transfer signals for the sleep-tech IP landscape
Venue strategy in medical device patent disputes can shift litigation economics as much as the underlying merits. This case is no exception.
Venue selection is a first-order strategic decision in device patent cases
ResMed's original choice of S.D. Cal. — a sophisticated patent forum — was ultimately overridden. Competitors and freedom-to-operate analysts should factor in that N.D. Ohio now controls the pace and outcome of this dispute. Monitoring the docket in Cleveland is essential for anyone watching US11602284B1.
Infringement claims under US11602284B1 remain live and unresolved
The transfer carries no finding on validity or infringement. Any company commercialising devices or methods for sleep disorder diagnosis and treatment should treat US11602284B1 as an active enforcement risk. The claim scope has not been construed by any court to date, meaning exposure is still being defined.
