Redwood Technologies v. Leedarson IoT: Six Wi-Fi Patents Settled in 264 Days
Redwood Technologies, LLC filed suit against Leedarson IoT Technology and Leedarson Lighting Co. in the Western District of Texas, asserting six patents covering IEEE 802.11 Wi-Fi standards including 802.11ac, 802.11ax, and 802.11n. The case resolved in 264 days via a Settlement and License Agreement, with all claims dismissed with prejudice.
Wi-Fi Standard Portfolio Enforcement Reaches License in Under Nine Months
On December 22, 2023, Redwood Technologies, LLC filed an infringement action in the Western District of Texas (Case No. 6:23-cv-00879) before Judge Alan D. Albright, asserting six United States patents — US8218501B2, US7359457B2, US7460485B2, US7917102B2, US7983140B2, and US10498571B2 — against Leedarson IoT Technology, Inc. and its affiliate Leedarson Lighting Co., Ltd. The asserted patents span core IEEE 802.11 wireless networking standards, including 802.11ac, 802.11ax (Wi-Fi 6), 802.11n, 802.11k, 802.11r, and Wi-Fi Multimedia (WMM), technologies central to modern smart lighting and IoT connectivity products.
The case closed on September 11, 2024, when the court granted the parties’ Stipulated Motion for Dismissal With Prejudice. The dismissal was expressly conditioned on a Settlement and License Agreement dated August 25, 2024, suggesting Leedarson obtained a license to Redwood’s Wi-Fi patent portfolio in exchange for resolution. A dismissal with prejudice means Redwood cannot re-assert these same claims against Leedarson on the same patents, providing the defendants with lasting protection from further suit on those issues.
At 264 days, the resolution is consistent with a pre-trial settlement reached before substantial claim construction or discovery expenditure — a pattern common in standard-essential patent (SEP) licensing enforcement actions in W.D. Texas. The specific financial terms of the license remain confidential under the settlement agreement. What is notable is that two Leedarson entities — an IoT technology company and a lighting manufacturer — were named as co-defendants, indicating Redwood’s enforcement targeted the full distribution chain. The public record does not disclose royalty rates, license scope, or which specific products were licensed.

264 days from filing to dismissal — faster than the W.D. Texas median for multi-patent Wi-Fi cases
Dismissed with prejudice: what the settlement and license means for both parties
Dismissal with prejudice bars future re-assertion on these patents
A dismissal with prejudice is a final adjudication on the merits for procedural purposes. Unlike a voluntary dismissal without prejudice, Redwood Technologies cannot re-file the same infringement claims against Leedarson on these six patents. The court’s order was expressly conditioned on the Settlement and License Agreement, making the license the operative instrument governing the parties’ ongoing rights.
Final — no re-filing permittedRedwood secures a license — enforcement objective likely achieved
For Redwood Technologies, dismissal with prejudice linked to a license agreement is consistent with the economic goal of most NPE enforcement actions: extracting a royalty stream rather than seeking injunctive relief. The settlement suggests the Wi-Fi portfolio was credible enough to drive licensing within nine months of filing. The portfolio remains available for assertion against third parties not party to this agreement.
License securedLeedarson obtains license certainty across its IoT and lighting product lines
Both Leedarson IoT Technology and Leedarson Lighting Co. are released from liability on all asserted claims. The license agreement — while confidential — likely provides a defined scope of authorised use for the six Wi-Fi patents, reducing future enforcement risk on those assets. The each-party-bears-own-costs order is standard in settled IP disputes and implies no finding of exceptional case conduct.
Licensed — claims extinguishedW.D. Texas remains a pressure point for Wi-Fi SEP licensing campaigns
This case is consistent with a broader pattern of Wi-Fi standard patent holders using Judge Albright’s W.D. Texas docket to accelerate licensing timelines. IoT device makers and smart lighting manufacturers building 802.11ac, 802.11ax, or 802.11n connectivity into products should treat Redwood’s portfolio as an active licensing risk. The multi-entity naming strategy — targeting both the technology arm and manufacturing affiliate — signals enforcement reach across corporate structures.

Official order — verbatim text
The court’s order expressly grants the parties’ stipulated motion and conditions dismissal on a named Settlement and License Agreement dated August 25, 2024. The ‘with prejudice’ designation is legally significant: it forecloses any future action by Redwood on the same claims against these defendants. The reference to a specific, titled agreement — rather than a general settlement — suggests the license terms are detailed and contractually binding, though their contents remain confidential. The cost order, requiring each party to bear its own fees, is standard for negotiated resolutions and indicates no exceptional-case finding under 35 U.S.C. § 285.
US8218501B2 — IEEE 802.11 Wi-Fi standard wireless communications portfolio
The six asserted patents — US8218501B2, US7359457B2, US7460485B2, US7917102B2, US7983140B2, and US10498571B2 — collectively cover foundational and advanced aspects of IEEE 802.11 wireless networking, spanning 802.11n, 802.11ac, 802.11ax (Wi-Fi 6), 802.11k, 802.11r, and Wi-Fi Multimedia (WMM). Application dates range from the mid-2000s through the late 2010s, reflecting both legacy standard contributions and more recent Wi-Fi 6 innovations. These patents sit at the intersection of physical layer signal processing, MAC layer protocols, quality-of-service mechanisms, and network management — all core to modern wireless device operation.
For IoT device manufacturers and smart lighting companies, the practical significance of this portfolio is substantial. 802.11ac and 802.11ax chipsets are now commodity components in connected lighting, home automation, and industrial IoT products. A portfolio asserting claims across multiple 802.11 amendments can cover the chip, the firmware, and the system implementation simultaneously — creating layered exposure. Redwood’s willingness to assert six patents simultaneously, and its success in reaching a license within 264 days, suggests the portfolio has sufficient claim breadth to survive early-stage validity challenges and compel licensing discussions.
Should you run an FTO analysis against US8218501B2 and Redwood’s Wi-Fi portfolio?
Any company designing or distributing products that incorporate IEEE 802.11ac, 802.11ax, 802.11n, 802.11k, or 802.11r Wi-Fi functionality — including smart lighting, IoT gateways, home automation hubs, or consumer electronics — should treat Redwood Technologies’ six-patent portfolio as a live commercial risk. The successful licensing outcome against Leedarson suggests these patents have credible claim coverage and enforcement momentum. Product teams integrating Wi-Fi chipsets from third-party silicon vendors should not assume chip-level licensing agreements cover all downstream system-level claims.
PatSnap Eureka’s FTO Search Agent enables IP and R&D teams to map product feature sets against the claim language of US8218501B2, US7359457B2, US7460485B2, US7917102B2, US7983140B2, and US10498571B2 in a structured, auditable workflow. Eureka can identify which product functions implicate which claim elements, flag design-around opportunities, and surface prior art relevant to validity assessment — all before a demand letter arrives. Given Redwood’s demonstrated willingness to litigate in W.D. Texas, early FTO diligence is materially cheaper than reactive licensing negotiations.

What this case signals for the Wi-Fi and IoT patent licensing landscape
A six-patent Wi-Fi enforcement action resolved in under nine months in W.D. Texas — here is what IP teams need to take away.
Redwood’s Wi-Fi portfolio remains active — other IoT players are exposed
The settlement and license with Leedarson does not exhaust or limit Redwood’s ability to assert US8218501B2 and the five co-asserted patents against other manufacturers. Companies shipping 802.11ac, 802.11ax, or 802.11n-enabled devices — particularly in smart home, lighting, and IoT categories — should assess their exposure to this portfolio now.
W.D. Texas timeline pressure is real: 264 days to settlement is no accident
Judge Albright’s docket is designed to move quickly. The sub-nine-month resolution here is consistent with W.D. Texas scheduling orders that compress pre-trial timelines. Defendants in this court typically face early claim construction and accelerated discovery, which raises the cost of fighting versus settling — a structural factor that favours patent holders with credible portfolios.
Redwood v Leedarson — key questions answered
Redwood Technologies asserted six patents: US8218501B2, US7359457B2, US7460485B2, US7917102B2, US7983140B2, and US10498571B2. All six relate to IEEE 802.11 wireless networking standards, covering 802.11ac, 802.11ax, 802.11n, 802.11k, 802.11r, and Wi-Fi Multimedia (WMM) protocols.
The case was resolved via a Settlement and License Agreement dated August 25, 2024, and dismissed with prejudice on September 11, 2024. Dismissal with prejudice means Redwood Technologies cannot re-assert the same claims against the Leedarson entities on these six patents. The settlement terms, including any royalty rates, remain confidential.
Leedarson IoT Technology, Inc. and Leedarson Lighting Co., Ltd. were both named as defendants, consistent with a strategy of targeting the full corporate value chain — both the technology/IP entity and the manufacturing affiliate. This approach is common in NPE enforcement actions to prevent defendants from structuring corporate separations to limit license scope.
The case was filed in the Western District of Texas (W.D. Tex.) and assigned to Judge Alan D. Albright, Case No. 6:23-cv-00879. Judge Albright’s Waco division is frequently selected by patent plaintiffs due to its historically fast scheduling orders and plaintiff-friendly procedural environment in patent cases.
The case signals that Redwood Technologies’ IEEE 802.11 patent portfolio is being actively enforced and has sufficient credibility to compel licensing within nine months of filing. IoT and smart lighting manufacturers integrating 802.11ac, 802.11ax, or 802.11n Wi-Fi should conduct freedom-to-operate analysis against Redwood’s six asserted patents and confirm that any existing chipset licenses extend to system-level claim coverage.
