LED patent assertion against Wayfair reaches agreed resolution in under eight months
On 29 September 2022, Lexington Luminance LLC filed suit against Wayfair, Inc. in the Western District of Texas (Judge Alan D. Albright) asserting infringement of US6936851B2, which covers a semiconductor light-emitting device and method for manufacturing the same. Wayfair — an e-commerce platform known for home goods — was targeted in connection with products falling within the patent's semiconductor LED claims.
The recorded basis of termination is Consent Judgment. The docket order states that, pursuant to an agreement by the parties and Federal Rule of Civil Procedure 41(a)(1)(A)(ii), Lexington Luminance and Wayfair stipulated to dismissal of all claims and counterclaims with prejudice, with each party bearing its own costs, expenses, and attorneys' fees. The specific terms underlying the parties' agreement are not disclosed in the available record.
The case closed on 15 May 2023 — just 228 days after filing — suggesting early resolution without extensive merits litigation. What drove the parties to agree at this stage, and whether any commercial terms accompanied the resolution, is not reflected in the public record.

US6936851B2 — Semiconductor Light-Emitting Device and Manufacturing Method


Any company manufacturing, importing, distributing, or retailing products incorporating semiconductor light-emitting devices should assess its exposure to US6936851B2. This case confirms that assertion is not limited to component manufacturers — e-commerce platforms and product resellers have been named. If your product portfolio includes LED-based lighting, displays, or consumer electronics sold in the US market, a targeted FTO review is warranted.
Official order — verbatim text
The stipulation invokes Rule 41(a)(1)(A)(ii) and dismisses all claims and counterclaims with prejudice, with each party bearing its own fees and costs. This language forecloses re-litigation of the same claims between these parties but contains no merits findings on infringement or validity. The absence of a fee-shifting award is consistent with a negotiated resolution rather than a contested judgment.
Consent judgment: what the agreed resolution means for both parties
A consent judgment is a binding court-entered judgment on agreed terms
A consent judgment is not merely a settlement agreement — it is a judgment formally entered by the court on terms the parties have agreed to, making it enforceable as a court order. Here the parties invoked Rule 41(a)(1)(A)(ii) as the procedural vehicle for stipulated dismissal. The recorded basis of termination is Consent Judgment; the docket order styles the disposition as a stipulated dismissal with prejudice. The specific terms of the parties' agreement are not disclosed in the available record.
Court-entered, binding & finalLexington Luminance's claims resolved with prejudice — case cannot be refiled
The consent judgment disposes of all of Lexington Luminance's claims against Wayfair with prejudice, meaning Lexington Luminance cannot re-assert the same claims based on the same conduct against Wayfair in a future action. US6936851B2 remains a live patent that Lexington Luminance may assert against other parties. The specific terms of any arrangement between the parties are not disclosed in the public record.
Claims dismissed with prejudiceWayfair exits the litigation with no public admission of liability
The stipulation contains no recorded finding of infringement or validity. Wayfair bears its own attorneys' fees and costs. The consent judgment insulates Wayfair from further litigation by Lexington Luminance on these specific claims. Whether any broader commercial arrangement accompanied the resolution is not reflected in the available record.
No liability finding on recordUS6936851B2 remains enforceable against the broader LED and lighting sector
A consent judgment resolves only the dispute between these specific parties. US6936851B2, covering semiconductor light-emitting device technology, is not invalidated by this resolution. Companies in the LED lighting, consumer electronics, and e-commerce product supply chain that have not taken steps to clear this patent should evaluate their exposure. The swift resolution — 228 days — suggests parties in this technology space may find early negotiated resolution preferable to full merits litigation.

PAE portfolio mappingFiling trends in semiconductor LED device and manufacturing patents
The technology class covering semiconductor light-emitting devices and manufacturing methods has seen sustained global filing activity from major players including Nichia, Cree, Samsung, and Osram. Understanding filing velocity, claim scope trends, and geographic coverage in this space helps R&D teams anticipate where the next enforcement vectors may emerge — and where design-around space exists.
LED filing trend analysisWayfair's IP strategy in an LED-heavy product catalogue
As a major e-commerce platform for home goods — a category saturated with LED lighting products — Wayfair's patent posture and supplier agreements determine its exposure to semiconductor device patent assertions. Examining Wayfair's own IP filings, any defensive publications, and its supplier indemnification practices can signal how it is building resilience against future LED patent campaigns.

Portfolio viewWhat this case signals for the semiconductor LED IP landscape
A rapid consent judgment in W.D. Texas over a core LED device patent carries forward-looking implications for the lighting and e-commerce supply chain.
W.D. Texas LED patent cases are resolving fast — budget for early settlement pressure
At 228 days, this case closed before meaningful merits litigation. Companies selling LED-integrated products through e-commerce channels should anticipate early assertion and price that risk into procurement and IP clearance budgets. Judge Albright's docket continues to attract patent assertion entities targeting product resellers.
US6936851B2 survives this action — downstream LED product sellers remain exposed
The consent judgment is party-specific. US6936851B2 was not invalidated or found unenforceable. Any company in the semiconductor LED supply chain — from OEM manufacturers to retail platforms — that has not cleared this patent faces potential exposure if Lexington Luminance pursues further assertions.
Lexington Luminance's assertion pattern: who is likely next in the LED space?
Patent assertion entities with a single core device patent often run sequential campaigns targeting similarly situated defendants. Mapping Lexington Luminance's prior filings and co-pending cases against other LED product distributors can surface which companies sit in the next wave of potential targets — and how they resolved their exposure.
FTO gap: semiconductor LED device claims and e-commerce product listings
The targeting of a product platform like Wayfair — rather than a manufacturer — signals that LED device patents may be asserted against retailers and distributors, not just component makers. An FTO analysis scoped to US6936851B2's claims against finished consumer lighting products sold through online channels is a materially different exercise than a manufacturer-focused clearance.
Lexington v Wayfair — key questions answered
The recorded basis of termination is Consent Judgment. The docket order states that the parties stipulated under Rule 41(a)(1)(A)(ii) to dismissal of all claims and counterclaims with prejudice, with each party bearing its own costs and attorneys' fees. The specific terms of any underlying agreement are not disclosed in the public record.
Lexington Luminance asserted US6936851B2 (application number US10/394686), which covers a semiconductor light-emitting device and method for manufacturing the same. The patent sits in the LED and semiconductor optoelectronics domain.
No. A consent judgment resolves only the dispute between Lexington Luminance and Wayfair. It contains no finding on the validity or enforceability of US6936851B2. The patent remains issued, presumptively valid, and potentially assertable against other parties.
The Western District of Texas, particularly before Judge Alan D. Albright, has been a preferred venue for patent assertion entities due to its historically fast scheduling and plaintiff-friendly procedural posture. This case is consistent with a broader pattern of LED and technology patent cases filed in that district by assertion-focused plaintiffs.
The stipulation provides that each party bears its own costs, expenses, and attorneys' fees. This means neither party was awarded fee-shifting under 35 U.S.C. § 285 or any other mechanism. This arrangement is typical of negotiated resolutions and does not imply any finding regarding the conduct or litigation position of either party.
