Redwood Technologies v. NXP Semiconductors: 8-Patent Wi-Fi Dispute Resolved in 306 Days
Redwood Technologies, LLC filed suit against NXP Semiconductors N.V. and its affiliates in the Western District of Texas, asserting eight patents covering Wi-Fi standards including IEEE 802.11ac, 802.11ax, 802.11n, and 802.11s across NXP’s chipsets, access points, automotive, and IoT devices. The case resolved with Redwood’s claims dismissed with prejudice — consistent with a negotiated settlement — in just over ten months.
Eight Wi-Fi Patents, One Global Chipmaker, and a Swift Texas Exit
On March 8, 2024, Redwood Technologies, LLC filed a patent infringement action in the Western District of Texas before Judge Alan D. Albright, targeting NXP Semiconductors N.V., NXP USA, Inc., and NXP B.V. The complaint asserted eight United States patents — US8155224B2, US9628300B2, US7688901B2, US7974371B2, US8744005B2, US7917102B2, US8873517B2, and US7664130B2 — directed at Wi-Fi signal processing and communications technology underlying the IEEE 802.11ac, 802.11ax, 802.11n, and 802.11s standards implemented in NXP’s semiconductor products.
The case closed on January 8, 2025, when the court granted the parties’ joint request for dismissal. Redwood’s claims against NXP USA were dismissed with prejudice, meaning Redwood cannot re-file the same claims against NXP USA in any federal court. NXP’s counterclaims and defenses were dismissed without prejudice, preserving NXP’s ability to reassert them if litigation were ever recommenced. Each party was ordered to bear its own attorneys’ fees, costs, and expenses — a standard feature of negotiated resolutions where neither side extracts a fee award.
A resolution in 306 days across an eight-patent portfolio targeting a global semiconductor leader suggests the parties likely reached a licensing or commercial arrangement, though the public record is silent on financial terms. The asymmetric dismissal structure — plaintiff with prejudice, defendant without — is a hallmark of a negotiated exit rather than a contested adjudication on the merits. What drove the precise settlement calculus, including any royalty rate or cross-license element, remains confidential and cannot be determined from court filings alone.

Dismissed with prejudice: what the dual-dismissal structure means for both sides
Dismissal with prejudice bars Redwood from re-filing these claims
A dismissal with prejudice operates as a final adjudication on the merits under federal procedural rules, extinguishing Redwood’s right to reassert the same eight patents against NXP USA in any U.S. federal court. This is the standard structure when a patent plaintiff has received consideration — typically a lump-sum or running royalty — and agrees to close the matter permanently. The court’s order does not disclose terms, but the with-prejudice designation is the procedural fingerprint of a fully resolved dispute.
Plaintiff claims: permanently closedRedwood exits with no re-filing right — but likely with commercial value extracted
By accepting dismissal with prejudice, Redwood formally surrenders its ability to pursue these eight patents against NXP USA again. This is consistent with a licensing resolution in which Redwood received value — whether a lump-sum payment, a royalty agreement, or a broader cross-license. Patent licensing entities typically accept with-prejudice dismissals only once they are satisfied the commercial objective has been met. The public record does not confirm any payment, so this inference should be treated as circumstantial.
Suggests licensing resolution reachedNXP’s counterclaims survive — preserved without prejudice
NXP’s counterclaims and defenses were dismissed without prejudice, meaning NXP retains the right to re-assert invalidity or other defenses if litigation over these patents ever resurfaces against a different NXP entity or in a different forum. This asymmetry is commercially significant: NXP did not waive its right to challenge the patents’ validity, which could matter if Redwood pursues related actions against NXP’s customers or other defendants in the 802.11 ecosystem.
NXP validity defenses preservedEight 802.11 patents remain live weapons against the broader Wi-Fi supply chain
Because the patents were not adjudicated on the merits and no IPR or invalidity ruling was issued, all eight patents in Redwood’s portfolio remain enforceable. Suppliers of 802.11ac, 802.11ax, 802.11n, and 802.11s chipsets — particularly those serving automotive, IoT, and mobile segments — should note that Redwood’s portfolio has now been tested against a major defendant and resolved on undisclosed terms. This outcome may embolden further licensing campaigns or litigation against other implementers in the Wi-Fi standards space.

Official order — verbatim text
The court order reflects a jointly negotiated resolution rather than a contested judgment. The asymmetric dismissal — Redwood’s claims with prejudice, NXP’s counterclaims without prejudice — is procedurally significant: it confirms the dispute is permanently closed as to these parties on these claims, but NXP’s invalidity and other defenses were not waived. The fee-neutral order, with each party bearing its own costs, is consistent with a confidential commercial settlement and indicates neither party prevailed on any motion entitling them to fee-shifting under 35 U.S.C. § 285.
US8155224B2 — Wi-Fi signal processing and 802.11 standard communications
The eight patents asserted in this case — spanning application numbers filed between the mid-2000s and early 2010s — collectively cover signal processing, transceiver architecture, and protocol layer technology fundamental to the IEEE 802.11 family of Wi-Fi standards. US8155224B2 and its co-asserted patents address technologies including OFDM-based receiver design, MIMO spatial stream processing, channel estimation, and MAC/PHY layer communications — core building blocks of 802.11n, 802.11ac, and 802.11ax (Wi-Fi 6) chipsets deployed across billions of connected devices globally.
This portfolio’s strategic value lies in its breadth across multiple Wi-Fi generations and its applicability to diverse product categories: NXP’s accused products span access points, mobile devices, automotive connectivity modules, and IoT hardware. For semiconductor vendors, the risk is amplified because infringement liability can attach at the chip level, potentially exposing downstream OEM customers. The unadjudicated status of all eight patents following this settlement means the portfolio retains full enforcement potential against any manufacturer or integrator implementing 802.11-compliant silicon or firmware.
Should your team run an FTO against US8155224B2 and Redwood’s Wi-Fi portfolio?
Any company designing, manufacturing, or integrating IEEE 802.11ac, 802.11ax, 802.11n, or 802.11s compliant hardware or firmware should treat this portfolio as an active risk. The eight patents cover receiver architectures, MIMO processing, and protocol layer technology present in virtually every modern Wi-Fi chipset. Automotive Tier 1 suppliers, IoT platform vendors, access point OEMs, and mobile device makers — particularly those sourcing from NXP or similar semiconductor vendors — face potential direct or indirect exposure.

W.D. Texas remains a viable venue for multi-patent Wi-Fi licensing campaigns
Judge Albright’s docket continues to attract patent licensing entities with standard-essential or standard-related Wi-Fi portfolios. The 306-day resolution here — without reaching claim construction or trial — suggests defendants may face settlement pressure before full merits adjudication. Companies implementing 802.11ac, 802.11ax, or 802.11n should monitor new filings in this district proactively.
Redwood’s eight-patent portfolio is still active and unadjudicated on the merits
No court has ruled on the validity or scope of US8155224B2 or the seven co-asserted patents. The with-prejudice dismissal resolves only claims against NXP USA — not NXP B.V., not NXP’s customers, and not other industry participants. Chipset vendors, OEMs, and system integrators deploying 802.11 compliant devices should consider whether their exposure to this portfolio has been assessed.
Redwood v NXP — key questions answered
Redwood Technologies asserted eight U.S. patents: US8155224B2, US9628300B2, US7688901B2, US7974371B2, US8744005B2, US7917102B2, US8873517B2, and US7664130B2. All relate to Wi-Fi signal processing and communications technology covering IEEE 802.11ac, 802.11ax, 802.11n, and 802.11s standards implemented in NXP’s semiconductor devices.
Dismissal with prejudice followed a joint request by both parties announcing they had resolved all claims. A with-prejudice dismissal permanently bars Redwood from re-filing the same claims against NXP USA. This structure is consistent with a negotiated settlement, though specific financial terms are not disclosed in the public court record.
NXP’s counterclaims and defenses — which likely included patent invalidity arguments — were dismissed without prejudice, meaning NXP did not waive those defenses. If Redwood were to pursue related claims against NXP entities or customers in a different forum, NXP could potentially reassert invalidity or other defenses. This asymmetry suggests NXP negotiated to preserve its legal options.
The accused products include NXP Wi-Fi compliant devices implementing IEEE 802.11ac, 802.11ax, 802.11n, and 802.11s standards, spanning access points, mobile devices, automotive connectivity modules, and IoT devices, including the underlying hardware, software, and firmware components in NXP’s semiconductor product lines.
Yes. The dismissal in Case 6:24-cv-00127 did not include any adjudication on patent validity or claim scope. No IPR petition outcome or claim construction order is reflected in the public record. All eight patents — including US8155224B2 and the seven co-asserted patents — remain issued, presumptively valid, and enforceable against other parties in the 802.11 supply chain.
