VDPP, LLC v. Subway IP LLC: 3D Visual Tech Patents Settled in 89 Days
VDPP, LLC asserted two patents covering sustained 3D motion imaging and variable-tint filter spectacles against Subway IP LLC in Florida’s Southern District. The parties reached a settlement within 89 days of filing, closing the case before any substantive court rulings on the merits.
A rapid pre-trial settlement in a niche 3D imaging patent dispute
VDPP, LLC filed suit on 24 September 2025 in the United States District Court for the Southern District of Florida (Case No. 1:25-cv-24399) against Subway IP LLC, asserting infringement of two patents: US7030902B2, covering a method for creating the appearance of sustained three-dimensional motion of unlimited duration using a finite number of pictures (‘Eternalism’), and US9948922B2, covering faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials.
The case closed on 22 December 2025 — just 89 days after filing — when the parties submitted a Joint Motion to Stay All Deadlines and Notice of Settlement. Judge Jacqueline Becerra ordered the parties to file a Joint Stipulation for Dismissal within 30 days, with the case closed administratively in the interim. The court retained jurisdiction to reopen proceedings if settlement completion failed, consistent with standard settlement-stay practice.
An 89-day resolution is notably swift for a multi-patent infringement action and typically signals either a pre-existing licensing relationship, a straightforward royalty negotiation, or an early recognition by one party of exposure or claim weakness. The precise financial terms and scope of any licence grant remain unknown from the public record, leaving open whether Subway IP LLC obtained a full licence, a covenant not to sue, or another form of resolution.
Filing to Case Stayed in 89 days
89 days — well under the median district court patent case duration of 2–3 years
Joint settlement reached: what the court order means for both parties
Settlement stay order — no merits ruling issued
Judge Becerra’s order stayed all deadlines and administratively closed the case upon the parties’ joint notice of settlement. No claim construction, validity ruling, or infringement finding was entered. The court ordered a Joint Stipulation for Dismissal within 30 days, with a fallback of dismissal without prejudice if the parties fail to comply — preserving VDPP’s ability to refile if settlement breaks down.
No merits adjudicationDismissal terms not yet specified in public record
The court order contemplates a forthcoming Joint Stipulation for Dismissal but does not itself specify whether dismissal will be with or without prejudice. If the parties fail to file the stipulation, the court will dismiss without prejudice by default. Whether the final stipulation includes a with-prejudice dismissal — which would bar refiling — depends on the agreed settlement terms, which are not publicly disclosed at this stage.
Dismissal terms pendingVDPP retains patent validity — claims untested on merits
Because the case settled before any substantive ruling, US7030902B2 and US9948922B2 emerge with their validity and enforceability legally intact. No adverse claim construction or invalidity finding was entered. VDPP retains full freedom to assert these patents against other targets, potentially using the settlement as leverage in future licensing discussions — though the settlement terms themselves are confidential.
Patents legally intactEarly settlement limits precedent but signals licensing risk
Subway IP LLC’s rapid settlement — without filing any substantive defence — is consistent with a calculated decision to avoid litigation costs and uncertainty over claim scope. For companies operating in 3D display, digital signage, or immersive media sectors, this outcome suggests VDPP’s patent portfolio carries sufficient perceived enforceability to compel early resolution. Competitors should assess exposure to these patents before deployment of related visual technologies.

Official order — verbatim text
The court’s order reflects a standard settlement-stay mechanism: no factual findings, no claim construction, and no merits disposition were entered. The instruction to file a Joint Stipulation for Dismissal within 30 days — with a default dismissal without prejudice — preserves both parties’ procedural positions. Critically, the court’s retention of reopen jurisdiction signals that formal settlement execution was still pending at the time of administrative closure, leaving the precise dismissal terms subject to the parties’ forthcoming stipulation.
US7030902B2 & US9948922B2 — Sustained 3D Motion and Adjustable Filter Spectacles
US7030902B2 (App. No. US10/054607) protects the ‘Eternalism’ method — a technique for creating the appearance of sustained, directional three-dimensional motion of unlimited duration using only a finite number of pictures. US9948922B2 (App. No. US15/683623) covers faster state transitioning in continuously adjustable 3Deeps filter spectacles through multi-layered variable tint materials. Together, these patents span both the content-generation and the display/viewing hardware dimensions of 3D visual experience delivery.
These patents are strategically significant for any company deploying 3D visual content in consumer-facing environments — including digital out-of-home advertising, retail experiential displays, and entertainment venue signage. The assertion against Subway IP LLC suggests VDPP views branded media and promotional content deployments as within the patents’ scope. With claim construction never having been performed by a court, the commercial boundaries of these patents remain undefined, heightening uncertainty for potential third-party adopters of similar 3D display techniques.
Should you run an FTO against US7030902B2 and US9948922B2?
Any company developing or deploying finite-frame 3D motion sequences for advertising displays, immersive retail environments, out-of-home digital signage, or 3D spectacle-based viewing systems should treat these two patents as active risk vectors. VDPP has demonstrated willingness to assert both patents together and to target IP holding entities of major consumer brands. Given that no court has construed either patent’s claims, the scope of infringement exposure remains legally uncertain — and commercially significant.

What this case signals for the 3D imaging and digital media IP landscape
An 89-day settlement with no substantive defence filed suggests VDPP’s 3D visual patents carry real licensing leverage in the current enforcement environment.
Pre-answer settlements typically reflect licensing-ready patent holders
When a defendant of Subway IP LLC’s scale settles within 89 days without filing an answer, it typically signals the plaintiff’s patents are viewed as sufficiently credible to warrant early resolution. VDPP’s portfolio — covering both 3D motion method and adjustable spectacle filter technology — appears positioned for continued assertion activity against further targets in digital display and immersive media.
No invalidity finding protects VDPP’s future enforcement options
Because no claim construction, IPR petition, or invalidity ruling was entered, US7030902B2 and US9948922B2 retain full presumptive validity. Any future defendant will face the same untested claim scope, meaning the settlement creates no defensive precedent that other accused infringers could cite to resist licensing demands or challenge claim construction.
VDPP v SUBWAY — key questions answered
VDPP, LLC asserted two patents: US7030902B2, covering the ‘Eternalism’ method for creating sustained 3D motion-direction appearance using a finite number of pictures, and US9948922B2, covering faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials.
The case settled within 89 days of filing. On 22 December 2025, Judge Jacqueline Becerra entered an order staying all deadlines following the parties’ Joint Motion and Notice of Settlement. The court ordered a Joint Stipulation for Dismissal within 30 days, with administrative closure in the interim. No merits rulings were entered.
No. Because the case settled before any substantive ruling, neither patent received a claim construction order, validity determination, or infringement finding. Both patents retain their presumptive validity and remain fully enforceable. The settlement creates no legal precedent that third parties could use to challenge or narrow these patents.
The order administratively closed the case and required the parties to file a Joint Stipulation for Dismissal within 30 days. If they fail to do so, the case is dismissed without prejudice automatically. Whether the final dismissal is with or without prejudice depends on the parties’ stipulation, which had not been publicly filed at the time of administrative closure.
US7030902B2, held by VDPP, LLC, protects a method called ‘Eternalism’ — a technique for creating the visual appearance of sustained three-dimensional motion-direction of unlimited duration using only a finite number of pictures. It was filed under application number US10/054607 and forms part of VDPP’s 3D visual technology patent portfolio alongside US9948922B2.
