NetMomentum LLC v. Samsung: RFID & Dual-Screen Patent Dispute Dismissed With Prejudice
In a case that closed as quietly as it began, NetMomentum LLC v. Samsung Electronics Co., Ltd. (Case No. 2:24-cv-00888) concluded on March 28, 2025, with a joint stipulation of dismissal with prejudice — just 145 days after filing. The dispute, centered on RFID technology and dual-screen mobile device patents, was litigated before Chief Judge Rodney Gilstrap in the Eastern District of Texas, one of the nation’s most active patent litigation venues.
NetMomentum LLC asserted two patents — US9351334B1 (semi-transparent RFID tags) and US7714726B2 (two-sided dual-screen mobile phone devices) — against Samsung Electronics, a global leader in consumer electronics and mobile technology. The abrupt mutual dismissal, with each party bearing its own costs and fees, raises immediate questions about pre-trial settlement dynamics, patent strength, and assertion strategy in high-stakes RFID patent infringement and mobile device litigation.
For patent attorneys, in-house counsel, and R&D professionals navigating overlapping IP landscapes, this case offers instructive signals about patent assertion strategies and litigation risk management.

Litigation Timeline & Procedural History
| Complaint Filed | November 3, 2024 |
| Case Closed | March 28, 2025 |
| Total Duration | 145 days |
NetMomentum filed its complaint on November 3, 2024, selecting the Eastern District of Texas — a deliberate strategic choice. Chief Judge Rodney Gilstrap, who presides over this district, is among the most experienced patent jurists in the country, managing one of the highest volumes of patent dockets nationally.
The case closed at the first-instance (district court) level without progressing to claim construction, summary judgment, or trial. The 145-day duration from filing to dismissal suggests that dispositive negotiations — whether resulting in a licensing agreement, a covenant not to sue, or simply a mutual walk-away — began almost immediately after the complaint was served.
No specific intermediate milestones, motions, or Markman hearings appear in the public record prior to dismissal, indicating that substantive merits litigation was avoided entirely. The speed of resolution is notable even by Eastern District standards, where early-stage settlements are not uncommon but rarely occur at this pace.
The Verdict & Legal Analysis
Outcome
On March 28, 2025, Chief Judge Rodney Gilstrap accepted and acknowledged the Joint Stipulation of Dismissal with Prejudice (Dkt. No. 22), filed pursuant to Fed. R. Civ. P. 41(a)(1)(A)(ii). All claims asserted by NetMomentum against Samsung were dismissed with prejudice. Reciprocally, any counterclaims by Samsung against NetMomentum were also dismissed with prejudice. Each party was ordered to bear its own attorneys’ fees and costs — a standard allocation in negotiated dismissals absent a finding of exceptionality under 35 U.S.C. § 285.
No damages were awarded. No injunctive relief was granted. All pending motions were denied as moot.
Verdict Cause Analysis
The case was captioned as a straightforward patent infringement action. However, the dismissal with prejudice — rather than without prejudice — is legally significant. A dismissal with prejudice bars NetMomentum from reasserting these same claims against Samsung on the same patents. This outcome functionally forecloses future litigation between these parties on US9351334B1 and US7714726B2.
The mutual cost-bearing arrangement is characteristic of one of several scenarios:
- • Confidential licensing resolution: Samsung may have entered a licensing agreement with NetMomentum, eliminating the need to continue litigation — a common outcome in NPE assertions.
- • Covenants not to sue: Samsung may have secured assurances broad enough to make continued defense unnecessary.
- • Voluntary walk-away: NetMomentum may have assessed litigation risk — including potential inter partes review (IPR) petitions challenging patent validity — and determined that a negotiated exit was preferable.
Without disclosure of financial terms, the precise resolution mechanism remains confidential. However, the with prejudice designation strongly suggests a negotiated resolution rather than a unilateral abandonment.
Legal Significance
The case did not reach claim construction or trial, limiting its direct precedential value. However, it reinforces several notable litigation dynamics:
- • Eastern District velocity: Even in patent-favorable jurisdictions, defendants with strong counsel can achieve rapid resolution before costly litigation phases begin.
- • NPE assertion patterns: The dual-patent assertion across two distinct technology areas (RFID and dual-screen mobile devices) reflects a common NPE bundling strategy designed to maximize licensing leverage.
- • Rule 41 mechanics: The use of Rule 41(a)(1)(A)(ii) — requiring both parties’ stipulation — underscores that Samsung actively participated in shaping dismissal terms rather than being subjected to a unilateral withdrawal.

Industry & Competitive Implications
The NetMomentum v. Samsung dispute reflects broader trends in RFID patent litigation and mobile device IP assertion. RFID technology, widely deployed in retail, logistics, healthcare, and smart packaging, continues attracting NPE interest as adoption scales globally. Similarly, foldable and dual-screen mobile devices — a category Samsung has pioneered — generate recurring patent exposure.
For Samsung, this represents one of many concurrent IP disputes managed across its global portfolio. Samsung’s litigation posture — deploying specialized Eastern District counsel and pursuing rapid resolution — reflects a mature, cost-conscious defense strategy honed through years of high-volume patent litigation.
For the broader technology sector, this case signals that patent assertion in RFID and dual-display mobile technology remains commercially viable, even when cases resolve pre-merits. Companies investing in these technology spaces should monitor NPE portfolio acquisitions and consider proactive licensing or USPTO post-grant proceedings as risk mitigation tools.
