Redwood Technologies v. NXP Semiconductors: 7-Patent Wi-Fi Dispute Dismissed With Prejudice
Redwood Technologies, LLC asserted seven patents covering IEEE 802.11ax, 802.11n, 802.11ac, and 802.11r Wi-Fi standards against NXP Semiconductors and its subsidiaries in the Western District of Texas. The parties resolved all claims after 306 days, with Redwood’s infringement claims dismissed with prejudice — foreclosing any refiling against NXP on these patents.
Seven Wi-Fi Patents, One Resolution: Redwood vs. NXP in Waco
On March 8, 2024, Redwood Technologies, LLC filed suit against NXP Semiconductors N.V., NXP B.V., and NXP USA, Inc. in the Western District of Texas before Judge Alan D. Albright, asserting infringement of seven U.S. patents directed at core Wi-Fi standard technologies, including IEEE 802.11ax (Wi-Fi 6), 802.11n, 802.11ac, and 802.11r fast BSS transition. The accused products span NXP’s Wi-Fi compliant silicon components, access points, mobile devices, automotive systems, and IoT devices — a broad product footprint touching several high-volume markets.
The case closed on January 8, 2025, when the parties jointly announced resolution of all claims. Judge Albright entered an order dismissing Redwood’s claims against NXP USA with prejudice, while NXP’s counterclaims and defenses were dismissed without prejudice. Each party bears its own attorneys’ fees, costs, and expenses. The with-prejudice dismissal of Redwood’s claims is the operative legal consequence: Redwood cannot relitigate the same infringement allegations against NXP on these seven patents.
The 306-day resolution timeline suggests the parties reached agreement before significant claim construction or trial preparation costs accumulated — consistent with a negotiated licensing resolution or cross-licensing arrangement, though the public record does not disclose financial terms. The asymmetric dismissal structure — plaintiff’s claims with prejudice, defendant’s counterclaims without — is a common settlement signature that may reflect NXP’s desire to preserve optionality on invalidity counterclaims. What drove Redwood’s acceptance of a with-prejudice exit, and whether a license was granted, remains undisclosed.

Dismissed with prejudice: what the January 2025 order means for both parties
With-prejudice dismissal permanently bars Redwood’s claims
A dismissal with prejudice operates as a final adjudication on the merits. Redwood Technologies cannot refile these same infringement claims against NXP on any of the seven asserted patents. This is the strongest form of closure available short of a trial verdict, and it was entered by stipulation — meaning both parties agreed to this outcome. NXP’s counterclaims were separately dismissed without prejudice, preserving NXP’s right to raise invalidity or other defenses in future proceedings.
Claim preclusion appliesRedwood forfeits future enforcement rights against NXP on these patents
By accepting a with-prejudice dismissal, Redwood Technologies permanently relinquishes the right to sue NXP on these seven Wi-Fi patents. This outcome is consistent with a negotiated resolution — likely involving a license or lump-sum payment — but the public record does not confirm any financial terms. Redwood retains the ability to enforce these patents against other parties in the market, as the dismissal is party-specific.
No public license disclosureNXP secures finality on infringement claims, preserves counterclaim rights
NXP exits the litigation free from Redwood’s infringement claims on all seven patents. Critically, its own counterclaims — which likely included patent invalidity challenges — were dismissed without prejudice. This asymmetric structure is typically negotiated to give the defendant future optionality: NXP could theoretically pursue IPR or declaratory judgment actions on these patents if Redwood asserts them against other NXP products or affiliates. Each party bearing its own costs signals neither side viewed this as a full win.
Counterclaim optionality retainedWi-Fi 6 and automotive IoT IP remains commercially active
Redwood’s seven-patent portfolio targeting 802.11ax, 802.11n/ac, and 802.11r remains enforceable against the broader market. Other Wi-Fi chipset vendors, automotive connectivity suppliers, and IoT device manufacturers should treat this case as a signal that Redwood is actively licensing this portfolio. The W.D. Texas venue and the breadth of accused products — spanning silicon, software, firmware, access points, and vehicles — suggests a licensing campaign rather than a single-target dispute.

Official order — verbatim text
The January 8, 2025 dismissal order reflects a negotiated resolution in which Redwood’s infringement claims against NXP USA were extinguished with prejudice — a res judicata bar on these specific claims between these parties. The deliberate asymmetry is legally significant: NXP’s counterclaims, which almost certainly encompassed patent invalidity defenses, survive in a dormant state. This structure is consistent with NXP retaining the right to challenge patent validity should Redwood assert the same portfolio against NXP in different product contexts or jurisdictions. No merits ruling on infringement or validity was reached.
US8218501B2 and 6 further patents — IEEE 802.11 Wi-Fi standard technology
The seven asserted patents — US8218501B2, US7826555B2, US9374209B2, US7359457B2, US10270574B2, US7460485B2, and US7983140B2 — cover a range of physical layer, MAC layer, and protocol technologies underpinning the IEEE 802.11 Wi-Fi standard family. The portfolio spans innovations relevant to 802.11n (high-throughput MIMO), 802.11ac (gigabit Wi-Fi), 802.11ax (Wi-Fi 6 OFDMA), and 802.11r (fast BSS transition for seamless roaming), as well as Wi-Fi Multimedia (WMM) quality-of-service mechanisms. Application dates range across multiple filing generations, suggesting layered coverage of successive Wi-Fi standard iterations.
This portfolio’s commercial significance stems from its coverage of protocols now embedded in virtually every Wi-Fi-enabled device — from consumer routers and smartphones to automotive telematics units and industrial IoT modules. Any semiconductor vendor shipping 802.11ax, 802.11n/ac, or 802.11r-compliant chips, as well as OEMs integrating those chips into access points, vehicles, or connected devices, is a potential target. The breadth of accused NXP product categories — hardware, software, and firmware components across automotive, mobile, and IoT — indicates Redwood is pursuing standard-essential or standard-adjacent claims with wide applicability across the industry.
Should your team run an FTO analysis against Redwood’s 802.11 Wi-Fi patent portfolio?
Any company designing, manufacturing, or distributing products that incorporate IEEE 802.11ax, 802.11n, 802.11ac, or 802.11r compliant Wi-Fi components should treat this case as a trigger for FTO review. This includes Wi-Fi chipset vendors, SoC designers, access point manufacturers, automotive Tier 1 suppliers integrating connected modules, and IoT platform providers. The seven-patent scope and the explicit inclusion of software and firmware in accused products means exposure is not limited to silicon — application-layer and driver implementations may also be in scope.

Cases involving IEEE 802.11 Wi-Fi standard patents litigated in the Western District of Texas before Judge Albright, including comparable semiconductor and IoT enforcement actions.
What this case signals for the Wi-Fi semiconductor IP landscape
A seven-patent 802.11 infringement campaign ending in a with-prejudice settlement has clear downstream implications for Wi-Fi chip vendors and device OEMs.
Redwood’s 802.11 portfolio is active and likely generating licensing revenue
The with-prejudice resolution against a major Wi-Fi chipset vendor like NXP strongly suggests a licensing arrangement was reached. Patent licensing entities that resolve cases this way typically reinvest proceeds into further enforcement. Competitors of NXP supplying 802.11ax/n/ac/r chipsets or modules should anticipate outreach from Redwood Technologies or monitor for new filings.
W.D. Texas remains a preferred venue for Wi-Fi standard-essential patent campaigns
Judge Albright’s court was selected for a broad multi-defendant Wi-Fi campaign — consistent with its reputation for efficient docket management and plaintiff-friendly scheduling. Companies with significant U.S. Wi-Fi product revenue should ensure their freedom-to-operate analyses cover 802.11 standard-essential patents and monitor for new filings in the Western District of Texas.
Redwood v NXP — key questions answered
Redwood Technologies asserted seven U.S. patents: US8218501B2, US7826555B2, US9374209B2, US7359457B2, US10270574B2, US7460485B2, and US7983140B2. The patents cover technologies relevant to IEEE 802.11ax, 802.11n, 802.11ac, and 802.11r Wi-Fi standards, including physical layer, MAC layer, fast BSS transition, and Wi-Fi Multimedia quality-of-service protocols.
The with-prejudice dismissal was entered by joint stipulation of the parties on January 8, 2025, indicating the parties reached a resolution. A with-prejudice dismissal means Redwood cannot refile the same infringement claims against NXP on these seven patents. The public record does not disclose whether a license or financial settlement was part of the resolution.
The order dismissed Redwood’s infringement claims against NXP with prejudice (permanently barring refiling) while dismissing NXP’s counterclaims without prejudice (preserving NXP’s right to raise invalidity or other defenses later). This asymmetric structure is a common negotiated settlement feature, suggesting NXP retained optionality to challenge patent validity — for example via IPR — if Redwood asserts the portfolio against NXP in other contexts.
The accused products included NXP’s Wi-Fi compliant components implementing IEEE 802.11ax, 802.11n, 802.11ac, and 802.11r standards, as well as Wi-Fi Multimedia (WMM)-compliant products. The scope extended beyond chips to access points, mobile devices, automotive systems, and IoT devices incorporating NXP hardware, software, and firmware components.
The public record suggests Redwood Technologies is an active patent licensing entity enforcing a portfolio of 802.11 standard-related patents. The with-prejudice resolution against NXP is party-specific and does not limit Redwood’s ability to assert the same patents against other Wi-Fi chipset vendors, device OEMs, automotive suppliers, or IoT manufacturers. Companies shipping 802.11ax/n/ac/r compliant products should monitor for new enforcement actions.
