Mobile Health v. Samsung: Stress-Monitor Patent Case Dismissed With Prejudice
Mobile Health Innovative Solutions filed suit against Samsung Electronics in the Eastern District of Texas, asserting US11468984B2 against the Galaxy Watch5 Pro’s stress-level calculation features. The parties jointly filed a Rule 41 dismissal with prejudice after 263 days — extinguishing all claims and barring refiling. Each party bears its own costs.
Wearable stress-monitoring patent claim ends in permanent dismissal
On 16 February 2024, Mobile Health Innovative Solutions, LLC filed a patent infringement action against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas (Case No. 2:24-cv-00106), before Judge Rodney Gilstrap. The suit centred on US11468984B2, a patent covering methods for calculating stress levels, which Plaintiff alleged was practised by the Galaxy Watch5 Pro through its compatibility with the Samsung Health and Samsung Health Monitor apps.
On 5 November 2024 — 263 days after filing — the parties jointly filed a stipulated notice of dismissal under FRCP 41(a)(1)(A)(ii). The court accepted the notice and dismissed all claims with prejudice, meaning Mobile Health is permanently barred from reasserting the same claims against Samsung on this patent. No damages were awarded, and the court ordered each side to bear its own litigation costs, suggesting a resolution that left no financial winner on the record.
The sub-nine-month lifespan is consistent with a negotiated resolution — likely a licence, covenant not to sue, or walk-away agreement — reached before significant merits briefing. The public record is silent on whether any commercial arrangement accompanied the dismissal. What is clear is that the with-prejudice designation forecloses any future attempt by Mobile Health to relitigate these specific claims against Samsung’s wearable health products.

Dismissed with prejudice: what the joint stipulation means for both parties
FRCP 41(a)(1)(A)(ii): joint stipulated dismissal with prejudice
Rule 41(a)(1)(A)(ii) allows parties to dismiss an action without a court order when all parties who have appeared sign the stipulation. The ‘with prejudice’ designation is the critical qualifier — it operates as a final adjudication on the merits under res judicata, permanently barring Mobile Health from filing the same patent claims against Samsung in any court.
Permanent bar on refilingMobile Health loses the right to refile — but the patent itself survives
A dismissal with prejudice extinguishes Mobile Health’s claims against Samsung specifically, but does not invalidate US11468984B2. The patent remains in force and can still be asserted against other defendants. The with-prejudice terms do suggest Mobile Health accepted meaningful concessions — whether commercial or strategic — in exchange for the permanent release of Samsung.
Patent still enforceable vs. othersSamsung secures permanent protection from this specific claim
Samsung obtained a with-prejudice dismissal, which is the strongest possible exit short of a final invalidity ruling. The Galaxy Watch5 Pro and its stress-monitoring functionality are permanently shielded from further suit by Mobile Health on US11468984B2. The own-costs order is neutral — neither side paid the other’s fees — consistent with a negotiated exit rather than a litigation win.
Full liability release securedWearable health IP remains a live enforcement risk across the sector
The case resolving privately before any claim construction or merits ruling means US11468984B2’s scope was never publicly tested. Competing wearable manufacturers — particularly those with stress-level or biometric monitoring features — should note that the patent’s validity and claim breadth remain untested in litigation. Mobile Health retains full enforcement rights against all non-Samsung targets.

Official order — verbatim text
The court’s order does not adjudicate the merits of infringement or validity — it accepts and acknowledges a joint party stipulation. The operative legal effect flows entirely from the ‘with prejudice’ designation in the FRCP 41(a)(1)(A)(ii) notice, not from any judicial finding. This means US11468984B2’s claims have never been construed or tested. The own-costs directive is standard in joint stipulations and does not signal which party held the stronger litigation position.
US11468984B2 — Wearable stress-level calculation technology
US11468984B2 (application number US16/850984) covers methods and systems for calculating stress levels in a wearable device context. The patent sits within the mobile and wearable health-monitoring domain, addressing algorithmic approaches to deriving stress metrics — likely from biometric sensor inputs such as heart rate variability. Its asserted application to the Galaxy Watch5 Pro’s Samsung Health and Samsung Health Monitor apps indicates claims directed at software-implemented health analytics executed on or in conjunction with consumer wearable hardware.
Stress-level monitoring is one of the fastest-growing feature categories in consumer wearables, with Apple, Google, Garmin, Fitbit, and Samsung all deploying competing implementations. A patent covering core stress-calculation methodology — particularly one that survived without an invalidity ruling — represents a meaningful enforcement asset. Because no claim construction has occurred, the breadth of US11468984B2 remains commercially uncertain, creating risk for any wearable manufacturer that has not conducted a freedom-to-operate analysis against its claims.
Should your wearable product team run an FTO against US11468984B2?
If your organisation develops or ships wearable devices with stress monitoring, HRV analysis, or integrated health app ecosystems, US11468984B2 warrants close scrutiny. Mobile Health has demonstrated willingness to assert this patent against a Tier-1 defendant in the most plaintiff-friendly US district court. The absence of any invalidity or non-infringement ruling means there is no public safe harbour — every competitor in this space carries unquantified exposure until the patent’s claims are independently mapped against your product’s feature set.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to run structured freedom-to-operate queries against US11468984B2’s claim language, identify prior art that could support an IPR petition, and benchmark your implementation against the specific functional steps asserted against Samsung.

With-prejudice exits protect Samsung but leave the patent fully armed
Mobile Health’s US11468984B2 exits this litigation without a single claim being construed or invalidated. For every wearable OEM that is not Samsung, the patent’s enforceability is exactly as strong today as it was before this suit was filed. Competitors offering stress or HRV monitoring should treat this outcome as a green light for continued assertion activity.
E.D. Tex. + Judge Gilstrap: a venue signal for future filings
Mobile Health chose Judge Gilstrap’s docket in the Eastern District of Texas — the most patent-plaintiff-friendly venue in the US. The case resolved in under nine months, consistent with settlement pressure common in that court before Markman. Any future assertion by Mobile Health on this or related patents is likely to follow the same venue strategy.
Mobile v Samsung — key questions answered
The dismissal with prejudice under FRCP 41(a)(1)(A)(ii) permanently bars Mobile Health from reasserting the same claims against Samsung. However, US11468984B2 itself remains valid and enforceable — Mobile Health retains full rights to assert it against any other defendant. No court ruling on infringement or validity was made.
No. The case was dismissed by joint stipulation before any merits ruling. There was no claim construction hearing, no summary judgment on validity, and no § 101 eligibility ruling. The patent’s validity and claim scope remain untested by any court in this litigation.
The public record does not disclose the reason. A joint dismissal with prejudice after 263 days — and before significant merits briefing — is consistent with a negotiated resolution, which could include a patent licence, a covenant not to sue, or a walk-away agreement. The own-costs order provides no additional clarity on commercial terms.
An own-costs order is standard in joint stipulated dismissals and does not imply either party won or lost. It means no attorneys’ fees were awarded under 35 U.S.C. § 285 and no cost-shifting occurred. It is neutral on the merits and consistent with both a private settlement and a straight walk-away.
The complaint identified the Galaxy Watch5 Pro as the accused product, specifically its compatibility with the Samsung Health app and Samsung Health Monitor app as the mechanism through which stress-level calculation allegedly infringed US11468984B2.
