NetMomentum LLC v. Gao Group, Inc. — RFID Patent Suit Dismissed in 27 Days
NetMomentum LLC asserted US7714726B2, covering semi-transparent RFID tag technology, against Gao Group, Inc. in the Southern District of New York. The case resolved by voluntary dismissal without prejudice in just 27 days — leaving the door open for future enforcement action.
A rapid RFID patent filing that ended before substantive litigation began
On 12 August 2025, NetMomentum LLC filed a patent infringement complaint against Gao Group, Inc. in the U.S. District Court for the Southern District of New York, before Judge Arun Subramanian. The action centred on US7714726B2, a patent covering semi-transparent RFID tags — a product category used across retail labelling, asset tracking, and supply chain identification. NetMomentum was represented by Isaac Rabicoff of Rabicoff Law LLC, a firm with a known track record in NPE-style patent enforcement.
The case closed on 8 September 2025 — just 27 days after filing — when the court granted NetMomentum’s request to dismiss the matter without prejudice. A dismissal without prejudice means no judgment on the merits was entered; NetMomentum retains the legal right to refile the same claims against Gao Group or other defendants at a future date, subject to applicable statutes of limitations.
The extreme brevity of this case — resolved before any responsive pleading or substantive motion practice is publicly recorded — is consistent with several scenarios: a pre-litigation settlement or licensing agreement reached quietly, a strategic withdrawal to pursue a different litigation venue or defendant, or an assessment that the case required further preparation. The public record does not disclose the reason for withdrawal, and no financial terms have been made available.
Filing to Voluntary dismissal in 27 days
27 days — well below the typical district court patent case lifespan of 2–3 years
Voluntarily dismissed: what the without-prejudice ruling means for both parties
Without prejudice: the case ends, but the dispute may not
A voluntary dismissal without prejudice under Federal Rule of Civil Procedure 41(a) terminates the current action without any adjudication on the merits. Critically, it does not extinguish the underlying patent claims. NetMomentum retains the right to refile an infringement action based on US7714726B2 against Gao Group or any other party, making this a procedural pause rather than a final resolution.
No merits ruling enteredWith or without prejudice? The public record is silent on terms
The court’s order confirms dismissal without prejudice — meaning the plaintiff did not waive future claims. A dismissal with prejudice would permanently bar NetMomentum from asserting the same patent claims against Gao Group. That outcome did not occur here. Whether the parties reached a private licensing arrangement or commercial settlement is not disclosed in public filings; the docket reflects only the procedural outcome.
Refiling remains possibleGao Group faces no judgment — but exposure persists
Gao Group, Inc. avoids any adverse ruling on infringement or validity of US7714726B2. However, because the dismissal carries no prejudice, Gao Group cannot treat this case as a definitive clearance. If no licensing agreement was reached, the company should treat the underlying RFID patent as a continued risk — particularly given the plaintiff’s use of a firm experienced in serial patent enforcement.
No clearance establishedRFID tag suppliers should note this patent remains active
US7714726B2 survives this proceeding fully intact. Any company manufacturing, importing, or distributing semi-transparent RFID tags should treat this case as a signal that the patent is being actively monitored and enforced. The speed of this dismissal — before Gao Group even filed a responsive pleading — suggests NetMomentum may be pursuing a broader licensing campaign rather than a single enforcement action.

Official order — verbatim text
The court’s order — granting the request to dismiss without prejudice — is purely procedural in scope. It resolves the action without evaluating the validity or infringement of US7714726B2. The without-prejudice designation is the operative term: it confirms that no claim-preclusion effect attaches, and NetMomentum’s patent rights remain unimpaired. Gao Group obtains no declaratory judgment, no invalidity finding, and no covenant not to sue from this outcome.
US7714726B2 — Semi-Transparent RFID Tag Technology
US7714726B2, filed under application number US11/124486, covers semi-transparent RFID tag technology — a design approach that integrates radio-frequency identification circuitry within a visually translucent tag substrate. This construction is commercially relevant in retail price labelling, luxury goods authentication, and asset tracking applications where label aesthetics and functionality must coexist. The patent’s claims likely address the physical construction, material layering, and antenna integration that enable both transparency and RF performance.
From a competitive intelligence standpoint, a patent asserting semi-transparent RFID tag construction sits at the intersection of materials technology and wireless identification — a sector experiencing sustained growth driven by retail inventory automation and supply chain digitalisation. Any supplier producing translucent or clear RFID inlays, labels, or tags for consumer goods, apparel, or logistics should assess whether their product architecture overlaps with the claim scope of US7714726B2. The patent’s assertion in this case suggests it is being actively maintained and commercialised through licensing.
Should your RFID product team run an FTO against US7714726B2?
If your organisation designs, manufactures, imports, or distributes semi-transparent or clear RFID tags, labels, or inlays — particularly for retail, apparel, or supply chain applications — US7714726B2 represents a patent risk that should be formally assessed. The filing of this action, even if quickly dismissed, signals active enforcement intent. R&D and product teams developing next-generation RFID tag constructions should not rely on the dismissal of this case as IP clearance.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US7714726B2 against your product specifications, surface the closest prior art that could support an invalidity argument, and identify design-around opportunities before a demand letter arrives. Eureka’s citation graph also helps identify whether related continuation or family patents extend the risk landscape beyond this single patent number.

What this case signals for the RFID technology IP landscape
A 27-day patent suit in S.D.N.Y. that ends without prejudice is rarely the end of the story for the underlying patent.
Voluntary dismissals this fast typically signal licensing activity
Cases resolved within 30 days of filing — before any substantive motion practice — frequently reflect a pre-litigation or early-stage licensing negotiation that reached a conclusion. If Gao Group agreed to a licence, US7714726B2 may now be used as leverage against other RFID tag suppliers in the same product category.

NetMomentum v Gao — key questions answered
NetMomentum LLC filed a patent infringement action against Gao Group, Inc. in the Southern District of New York on 12 August 2025, asserting US7714726B2 covering semi-transparent RFID tags. The case was voluntarily dismissed without prejudice on 8 September 2025 — just 27 days after filing — with no merits ruling entered.
A dismissal without prejudice means the court did not rule on the validity or infringement of US7714726B2. NetMomentum retains full rights to refile infringement claims against Gao Group or other defendants. The patent remains enforceable and the plaintiff’s enforcement options are unimpaired by this outcome.
US7714726B2 covers semi-transparent RFID tag constructions — tags that combine radio-frequency identification circuitry with a translucent substrate. Companies manufacturing, importing, or selling clear or semi-transparent RFID labels, inlays, or tags for retail, apparel, or logistics applications are potentially within the risk scope of this patent.
No. The voluntary dismissal without prejudice provides Gao Group with no declaratory judgment, no invalidity finding, and no covenant not to sue. Unless a private licensing or settlement agreement was reached — which is not disclosed in the public record — Gao Group remains potentially exposed to a refiled infringement action based on the same patent.
Rabicoff Law LLC, represented by Isaac Rabicoff, acted as plaintiff’s counsel for NetMomentum LLC in this case. The firm is associated with patent enforcement and NPE-style litigation campaigns. IP professionals in the RFID sector should monitor the firm’s docket for additional filings asserting US7714726B2 or related patents against other defendants.
