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.

Dismissal terms

Joint dismissal unpacked: with prejudice vs. without prejudice

Legal mechanism

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 closed
Asymmetric dismissal

Samsung’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: preserved
Cost ruling

No 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 ruling
Commercial implications

Confidential 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

“Before the Court is the Joint Motion to Dismiss (the “Motion”) filed by Plaintiff Headwater Research LLC (“Plaintiff”) and Defendants Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. (“Defendants”) (collectively, the “Parties”). (Dkt. No. 50.) In the Motion, the Parties represent that the above-captioned case has been resolved and request dismissal of Plaintiff’s claims for relief against Defendants WITH prejudice and Defendants’ claims, defenses and/or counterclaims for relief against Plaintiff WITHOUT prejudice. (Id. at 1.) Having considered the Motion, the Court finds that it should be and hereby is GRANTED. Accordingly, all of Plaintiff’s claims for relief against Defendants are dismissed WITH PREJUDICE and Defendants’ claims, defenses and/or counterclaims for relief against Plaintiff are dismissed WITHOUT PREJUDICE. Each party is to bear its own costs, expenses, and attorneys’ fees. All pending requests for relief in the abovecaptioned case not explicitly granted herein are DENIED AS MOOT. The Clerk is directed to CLOSE the above-captioned case.”

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 (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.

Freedom to operate

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.

Strategic implications

What 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.
