Headwater Research v. Samsung: Mobile Device Patent Case Ends in Agreed Dismissal
Headwater Research LLC asserted two mobile connectivity patents — US10028144B2 and US10080250B2 — against Samsung Electronics in the Eastern District of Texas, targeting Samsung’s mobile phones and tablets. The parties jointly resolved the dispute and secured a dismissal with prejudice in 423 days, suggesting a negotiated settlement outside the public record.
Headwater’s Mobile Patent Campaign Reaches Quiet Resolution Against Samsung
On August 2, 2024, Headwater Research LLC filed suit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas (Case No. 2:24-cv-00627), asserting infringement of US10028144B2 and US10080250B2. Both patents relate to mobile device functionality, and the accused products encompass Samsung’s broad portfolio of mobile phones and tablets — among the most commercially significant consumer electronics lines in the global market.
The case closed on September 29, 2025, following a Joint Motion to Dismiss filed by both parties. The court granted the motion in full: Headwater’s claims against Samsung were dismissed with prejudice, permanently barring re-assertion of those specific claims, while Samsung’s counterclaims and defenses were dismissed without prejudice, preserving Samsung’s ability to revive them if needed. Each party was ordered to bear its own litigation costs and attorneys’ fees.
The 423-day resolution timeline — well below the typical E.D. Tex. trajectory toward trial — and the structured asymmetry of the dismissal terms (with vs. without prejudice) together suggest the parties reached a confidential agreement, most likely a licensing arrangement or covenant not to sue. The public record is silent on financial terms. What remains unknown is whether Headwater secured royalties or a lump-sum payment, making this a representative example of NPE enforcement actions that resolve before substantive claim construction.

Joint dismissal unpacked: with prejudice vs. without prejudice
Dismissal with prejudice bars Headwater from re-filing these claims
A dismissal with prejudice under Federal Rule of Civil Procedure 41 is a final adjudication on the merits for res judicata purposes. Headwater cannot re-assert US10028144B2 or US10080250B2 against Samsung for the same accused products in any future action. This is the strongest form of finality available short of a jury verdict, and its presence here strongly suggests the parties reached a negotiated resolution satisfactory to both sides.
Plaintiff claims: permanently closedSamsung’s counterclaims survive — dismissed without prejudice
Samsung’s counterclaims and defenses — which typically include invalidity and non-infringement defenses — were dismissed without prejudice, meaning Samsung retains the option to revive them in future proceedings. This asymmetric structure is a hallmark of negotiated patent resolutions: the patent holder concedes finality on its infringement claims while the accused infringer preserves defensive optionality, including potential IPR petitions, should the patents surface in future disputes.
Samsung’s defenses: preservedNo fee-shifting: each party bears its own litigation costs
The court’s order that each party bear its own costs and attorneys’ fees is consistent with a mutually negotiated resolution. In contested patent cases, fee-shifting under 35 U.S.C. § 285 requires a finding of an ‘exceptional case.’ The absence of any such finding here, and the parties’ agreement on costs, suggests neither side sought to weaponise the fee issue — a further signal that the dispute resolved on commercially agreed terms rather than through adversarial litigation.
No § 285 exceptional case rulingConfidential resolution leaves market terms opaque for the industry
Because the resolution terms are not on the public record, competitors and licensees in the mobile device space cannot benchmark any royalty rate or lump-sum payment that may have been agreed. For Samsung’s rivals — other Android OEMs and mobile chipset makers — Headwater’s patent portfolio remains a live enforcement risk. The with-prejudice dismissal only extinguishes claims against Samsung; other potential defendants in the mobile ecosystem remain exposed to the same patents.

Official order — verbatim text
The court’s order reflects a textbook jointly-agreed dismissal structure in patent litigation. The deliberate asymmetry — Headwater’s claims extinguished with prejudice, Samsung’s counterclaims preserved without prejudice — is a negotiated construct, not a default judicial outcome. It is commercially rational: Headwater receives finality and cannot be dragged back into invalidity proceedings on these patents by Samsung, while Samsung retains the ability to challenge the patents via IPR or other proceedings if Headwater later asserts them against Samsung affiliates or related products. The fee-neutrality provision removes any lingering § 285 risk for both sides.
US10028144B2 & US10080250B2 — Mobile Device Connectivity and Background Data Management
US10028144B2 (App. No. 14/948,065) and US10080250B2 (App. No. 15/287,603) both sit within Headwater’s portfolio addressing how mobile devices manage background data activity, network connectivity prioritisation, and application-level communication control. These patents are representative of a class of IP that governs how smartphones and tablets allocate network resources across applications — a function embedded in virtually every modern mobile device operating system and chipset architecture.
Strategically, patents in this space carry significant enforcement leverage because the accused functionality is deeply integrated into device firmware and OS layers — design-around options are technically costly and commercially disruptive for high-volume OEMs. Headwater’s portfolio has been asserted against multiple major OEMs, suggesting a systematic licensing programme rather than a one-off dispute. For Samsung’s competitors and suppliers, these patents represent a live risk that the Samsung resolution does not extinguish — the IP remains valid and asserted.
Should your R&D team run an FTO against US10028144B2 and US10080250B2?
Any company developing or selling mobile phones, tablets, embedded modems, or mobile OS platforms that implement background data management, network connectivity scheduling, or per-application data policies should treat these patents as priority FTO targets. The accused product class in this case — Samsung’s full mobile device range — signals that broad commercial coverage is exactly what Headwater intends. The risk is not theoretical: active assertion campaigns against multiple OEMs are already on record.
PatSnap Eureka’s FTO Search Agent can map your product’s technical architecture against the claims of US10028144B2 and US10080250B2, identify claim elements that overlap with your implementation, surface prior art relevant to validity challenges, and benchmark against Headwater’s known assertion history across jurisdictions. Running this analysis before receiving a demand letter is significantly more cost-effective than reactive litigation strategy in E.D. Tex.

Portfolio viewWhat this case signals for the mobile device patent licensing landscape
Headwater’s E.D. Tex. campaign against Samsung illustrates how NPE enforcement against top-tier OEMs typically resolves before substantive merits rulings.
E.D. Tex. remains the dominant venue for mobile device NPE actions
The Eastern District of Texas continues to attract non-practising entities asserting mobile connectivity patents. Its procedural calendar and plaintiff-friendly reputation for scheduling orders create settlement pressure well before trial. Companies in the mobile OEM supply chain should monitor new filings in this district as an early indicator of licensing campaigns.
With-prejudice dismissals signal resolution but don’t neutralise the portfolio
Headwater’s patents survive this case intact and enforceable against third parties. A with-prejudice dismissal only forecloses claims against Samsung. Android OEMs, chipset manufacturers, and mobile platform providers that share Samsung’s product architecture should treat this outcome as a signal to review their own exposure to US10028144B2 and US10080250B2.
Headwater’s litigation history reveals a systematic licensing strategy worth mapping
Headwater Research has filed multiple infringement actions across major mobile OEMs. Mapping its full assertion history against claim overlap with your product lines — particularly around background data management and network connectivity — can quantify portfolio-level exposure before a demand letter arrives.
IPR timing windows remain open for third parties despite Samsung’s resolution
Samsung’s counterclaims were dismissed without prejudice, but third parties who have not been sued retain independent standing to petition for inter partes review of US10028144B2 and US10080250B2. The one-year IPR bar runs from service of a complaint — companies not yet sued face no bar and should evaluate petition viability now.
Headwater v Samsung — key questions answered
Headwater Research asserted two patents: US10028144B2 (App. No. 14/948,065) and US10080250B2 (App. No. 15/287,603). Both relate to mobile device background data management and network connectivity control and were asserted against Samsung’s mobile phones and tablets.
The dismissal was asymmetric. Headwater’s claims against Samsung were dismissed with prejudice, permanently barring re-assertion of those specific claims. Samsung’s counterclaims and defenses were dismissed without prejudice, preserving Samsung’s ability to revive them in future proceedings if needed.
No. A with-prejudice dismissal only forecloses Headwater’s claims against Samsung for the accused products in this specific case. US10028144B2 and US10080250B2 remain valid and enforceable. Other mobile OEMs, platform providers, and chipset manufacturers remain fully exposed to assertion of these patents.
Samsung’s counterclaims were dismissed without prejudice, which preserves Samsung’s defensive optionality. However, IPR petitioning rights are subject to the one-year bar from service of a complaint under 35 U.S.C. § 315(b). Samsung and third parties not yet served with a complaint retain independent standing to file IPR petitions and should evaluate this window promptly.
The court ordered each party to bear its own costs, expenses, and attorneys’ fees. This means no fee-shifting occurred under 35 U.S.C. § 285, which requires a finding of an ‘exceptional case.’ The mutual cost-bearing arrangement is consistent with a negotiated resolution and indicates neither party sought sanctions or exceptional-case designation against the other.
