Perfect Corp. v. Lennon Image Technologies: Dismissed With Prejudice After Settlement
Perfect Corp. brought a patent infringement action against Lennon Image Technologies LLC in the Western District of Texas, asserting US6624843B2 — a patent covering customer image capture and its use in retail systems. After 452 days of litigation, the parties reached a settlement, and the court dismissed all claims with prejudice while retaining jurisdiction to enforce the agreement.
Retail image-capture patent dispute ends in confidential settlement
Perfect Corp. filed this patent infringement action on 10 November 2022 in the Western District of Texas (Case No. 6:22-cv-01164), asserting US6624843B2 against Lennon Image Technologies LLC. The patent in suit covers customer image capture and its application within retailing systems — a technology domain with direct commercial relevance to virtual try-on, AR beauty, and AI-powered retail personalisation platforms. Perkins Coie LLP represented Perfect Corp., while Buether Joe & Counselors LLC appeared for Lennon Image Technologies.
The case closed on 5 February 2024 when the court granted the parties’ Joint Motion for Dismissal, ordering that all claims be dismissed with prejudice. Each party was directed to bear its own costs, expenses, and attorneys’ fees. Critically, the court retained jurisdiction over enforcement of the parties’ settlement agreement — a standard provision that signals a binding private settlement was reached, the terms of which are not reflected in the public record.
At 452 days, the case resolved faster than many patent infringement actions that proceed to claim construction or trial, suggesting the parties likely reached commercial terms before significant litigation expense was incurred. The with-prejudice dismissal permanently closes the door on Perfect Corp. refiling these specific claims. What drove resolution — licensing terms, design-arounds, or other commercial arrangements — remains confidential and cannot be confirmed from the public docket.

Dismissed with prejudice — settlement terms confidential, court retains enforcement jurisdiction
With prejudice: Perfect Corp.’s claims are permanently closed
A dismissal with prejudice is a final adjudication on the merits as a matter of law. Perfect Corp. cannot refile the same patent infringement claims against Lennon Image Technologies on US6624843B2 in any federal court. This finality is typically the quid pro quo the defendant secures in a settlement — trading payment or licence terms for permanent extinguishment of litigation risk.
Permanent bar on refilingEach party bears its own costs — no fee-shifting
The order specifies that each party bears its own costs, expenses, and attorneys’ fees. In U.S. patent litigation, fee-shifting under 35 U.S.C. § 285 requires a finding of an ‘exceptional case.’ The mutual cost-bearing arrangement here is consistent with a negotiated resolution where neither side sought — or could sustain — an exceptionality argument, and both parties preferred a clean exit over further contested proceedings.
No § 285 fee awardCourt retains jurisdiction — binding settlement exists
The court’s express retention of jurisdiction to enforce the parties’ settlement agreement is a strong indicator that a binding commercial settlement — likely a licence or cross-licence — was executed. Under Kokkonen v. Guardian Life (1994), federal courts retain post-dismissal enforcement jurisdiction only when explicitly reserved in the dismissal order, as done here. The private terms remain undisclosed.
Private licence likelyJoint motion signals collaborative, not adversarial, exit
The dismissal was filed as a joint motion — meaning both Perfect Corp. and Lennon Image Technologies agreed on the terms and timing of the exit. This contrasts with unilateral voluntary dismissals, which may be contested. A joint motion typically reflects that any commercial deal was fully executed before the filing, and that neither party anticipated further dispute over the resolution terms at the time of filing.

Stipulation of dismissal — official text
The order dismissing all claims with prejudice, with each party bearing its own costs and the court retaining enforcement jurisdiction, is the hallmark structure of a privately negotiated patent settlement. The with-prejudice designation means the plaintiff’s infringement claims on US6624843B2 are permanently extinguished as against this defendant. The retained enforcement jurisdiction clause indicates a binding settlement agreement was executed contemporaneously — courts do not retain such jurisdiction without an express undertaking. The mutual cost-bearing provision suggests neither party sought to characterise the outcome as a win on the merits.
US6624843B2 — Customer image capture and use in retailing systems
US6624843B2 (application number US09/733197) covers methods and systems for capturing customer images and applying those images within a retail context — a foundational claim set in what is now the virtual try-on and AI-powered retail personalisation sector. The patent’s application date predates the mainstream commercialisation of AR beauty and fashion tools, potentially giving it broad priority over later implementations. Its technical domain sits at the intersection of computer vision, image processing, and e-commerce UX — all high-growth areas currently attracting significant R&D investment.
From a competitive standpoint, US6624843B2 represents a potentially blocking position in the customer-facing image capture workflow for retail. Companies developing virtual try-on tools, AR cosmetics applications, or personalised product recommendation engines that rely on live or uploaded customer imagery should assess whether their pipeline intersects with the patent’s claims. The fact that this patent was asserted — and settled — against a named technology company suggests it is being actively managed as a commercial licensing asset rather than sitting dormant.
Should your retail imaging product be cleared against US6624843B2?
Any organisation building or licensing customer-facing image capture functionality for retail — including virtual try-on platforms, AR beauty tools, AI product recommendation systems, or in-store digital fitting rooms — should treat US6624843B2 as a relevant clearance target. The patent has been asserted in federal litigation and resolved via a confidential settlement, indicating it carries licensing leverage. Product teams shipping customer image capture features in a retail context should prioritise an FTO review before launch or market expansion.

What this case signals for the retail image-capture IP landscape
US6624843B2 has now been tested in litigation. Here is what competitors and product teams should take from this outcome.
US6624843B2 is litigation-active — it has been asserted and settled
The fact that this case reached a confidential settlement with prejudice suggests the patent was commercially viable enough to negotiate against. Any company operating in customer image capture, virtual try-on, or AI-driven retail personalisation should treat US6624843B2 as a live enforcement risk and assess their product architecture against its claims before expanding into adjacent retail applications.
Western District of Texas remains a preferred venue for patent plaintiffs
Despite post-Waco standing order changes, the Western District of Texas continues to attract patent cases. Defendants in this district face tight scheduling orders and limited transfer success. If your organisation is a potential infringement target in the image-capture retail space, understanding forum risk and building a pre-suit FTO record is more important than ever.
Perfect v Lennon — key questions answered
The case was dismissed with prejudice on 5 February 2024 pursuant to a joint motion by both parties. Each party bore its own costs and attorneys’ fees. The court retained jurisdiction to enforce a private settlement agreement, the terms of which are not public. Perfect Corp. cannot refile the same claims against Lennon Image Technologies.
Perfect Corp. asserted US6624843B2 (application number US09/733197), a patent covering customer image capture and its use in retailing systems. This patent is relevant to virtual try-on, AR beauty tools, and AI-powered retail personalisation platforms that rely on capturing and processing customer imagery.
A dismissal with prejudice is a final, binding termination of the claims on their merits as a matter of law. The plaintiff — here Perfect Corp. — is permanently barred from filing the same patent infringement claims against the same defendant in any U.S. federal court. It is a standard outcome in settled patent cases where the defendant negotiates permanent closure of litigation risk.
Under Kokkonen v. Guardian Life Insurance Co. (1994), federal courts may retain post-dismissal jurisdiction to enforce a settlement agreement if that retention is expressly included in the dismissal order. Here, the court did so — a strong signal that a binding private settlement agreement was executed between the parties, and that either party can return to the court to enforce it if the other defaults.
This patent has been actively asserted in federal litigation and resolved via a confidential settlement, suggesting it carries commercial licensing leverage. Companies operating in virtual try-on, AR cosmetics, customer image personalisation, or retail AI should conduct an FTO analysis against US6624843B2’s claims before launching or expanding products that capture and use customer imagery in a retail workflow.
