VDPP LLC v. Best Buy: Variable-Tint 3D Spectacles Patents Settled in 174 Days
VDPP, LLC filed suit against Best Buy Co., Inc. in the Eastern District of Texas asserting two patents covering faster state-transitioning technology for continuous adjustable 3Deeps filter spectacles using multi-layered variable-tint materials. The parties reached a confidential settlement and jointly moved for dismissal with prejudice in under six months.
Early Settlement Ends 3D Spectacles Patent Suit Against Best Buy
On March 8, 2024, VDPP, LLC filed an infringement action against Best Buy Co., Inc. in the United States District Court for the Eastern District of Texas (Case No. 2:24-cv-00164), presided over by Judge Rodney Gilstrap. VDPP asserted two patents — US10021380B1 and US9948922B2 — directed at faster state-transitioning technology for continuous adjustable 3Deeps filter spectacles using multi-layered variable-tint materials. Best Buy, as a major consumer electronics retailer, was accused of infringing through products it sold or distributed.
The case closed on August 29, 2024, after only 174 days, when the parties filed a Joint Motion to Dismiss with Prejudice confirming they had settled all claims. Judge Gilstrap granted the motion, ordering VDPP’s claims against Best Buy dismissed with prejudice and directing each party to bear its own costs and fees. Dismissal with prejudice means VDPP is permanently barred from reasserting the same claims against Best Buy, providing the retailer with a clean resolution on the public docket.
The sub-six-month resolution is notably swift for the Eastern District of Texas, which typically sees patent cases extend well beyond a year before trial. The self-bearing costs provision and the absence of any public damages figure are consistent with a confidential monetary settlement, though the specific terms remain undisclosed. What drove the rapid resolution — whether claim scope concerns, licensing economics, or commercial relationship considerations — is not apparent from the public record.
Filing to Dismissed with Prejudice in 174 days
174 days — resolved faster than the median E.D. Tex. patent case, suggesting early settlement pressure
Dismissed with prejudice after settlement: what the outcome means for both parties
Dismissal with prejudice bars future reassertion of these claims
A dismissal with prejudice operates as a final adjudication on the merits. VDPP is permanently precluded from filing a new action against Best Buy asserting the same claims under US10021380B1 and US9948922B2. This is the strongest form of closure available short of a full trial verdict, and it was entered here pursuant to a joint motion confirming settlement — meaning both parties consented to this finality.
Permanent claim barVDPP secures settlement but forfeits future action against Best Buy
By agreeing to dismissal with prejudice, VDPP received whatever consideration was negotiated in the confidential settlement while permanently closing the door on Best Buy as a future defendant for these patents. The patents themselves remain valid and enforceable against other parties. VDPP’s litigation posture — asserting niche 3D spectacles IP in the plaintiff-friendly E.D. Tex. — is consistent with a licensing-focused enforcement strategy targeting consumer electronics channels.
Settlement received; patents surviveBest Buy achieves permanent resolution on these two patents
Best Buy exits the dispute with prejudice protection, meaning VDPP cannot revive these specific claims. Each party bears its own costs, suggesting neither side extracted a cost-shifting victory. The settlement terms are confidential, so whether Best Buy paid a licensing fee or obtained a broader covenant not to sue is unknown from the public record. The swift resolution — 174 days — may reflect a commercially pragmatic decision to limit litigation exposure.
Clean exit; confidential termsVariable-tint 3D display IP remains active enforcement risk for consumer electronics sector
VDPP’s assertion of two patents directed at multi-layered variable-tint 3D spectacles technology signals continued enforcement activity in the consumer optics and display accessories space. Retailers and manufacturers selling or distributing 3D eyewear products — particularly those incorporating state-transitioning or electronically adjustable tint layers — should assess exposure to US10021380B1 and US9948922B2 independently. A settlement with Best Buy does not limit VDPP’s ability to pursue other defendants.

Official order — verbatim text
The Court’s order adopts the exact framing of the Joint Motion: the parties ‘have settled their respective claims for relief’ and jointly sought dismissal with prejudice. The explicit instruction that ‘each party shall bear its own costs and fees’ and the denial of all remaining relief as moot confirms a clean, no-fault closure. No merits ruling was issued, meaning neither patent was adjudicated valid, invalid, or infringed — the public record is silent on those substantive questions. The confidential settlement terms govern the commercial resolution between these two parties only.
US10021380B1 & US9948922B2 — Variable-Tint 3D Filter Spectacles Technology
US10021380B1 (Application No. US15/907614) and US9948922B2 (Application No. US15/683623) both relate to the 3Deeps family of 3D display technology — specifically, methods and structures enabling faster state transitions in spectacles that use multiple layers of variable-tint material to create the perception of depth in 2D-to-3D content rendering. The patents address the engineering challenge of reducing the lag between tint-state changes across lens layers, which is critical to viewer comfort and image quality in consumer 3D viewing applications.
These patents sit in a technically narrow but commercially relevant niche: the consumer 3D eyewear and display accessories market. As 3D-capable TVs, projectors, and cinema systems persisted in certain retail channels, the IP covering the optical filtering mechanisms in compatible spectacles became increasingly valuable for licensing enforcement. VDPP’s decision to assert both patents simultaneously against a major retail distributor like Best Buy suggests a portfolio strategy targeting entities with broad consumer electronics distribution rather than manufacturers specifically — a pattern worth monitoring across the retail electronics sector.
Should your 3D eyewear product line be cleared against US10021380B1?
Any company designing, manufacturing, importing, or distributing 3D spectacles that incorporate multi-layered electronically switchable or variable-tint lens materials should treat US10021380B1 and US9948922B2 as live enforcement risks. VDPP’s willingness to sue a major retailer — rather than only manufacturers — means that distribution-level exposure is real. R&D teams working on next-generation 3D display accessories or active-shutter eyewear should specifically map their state-transitioning architecture against the independent claims of both patents.
PatSnap Eureka’s FTO Search Agent can run a simultaneous claim-by-claim landscape analysis across both asserted patents, surfacing prior art, identifying design-around opportunities in the variable-tint layer sequence, and flagging continuation or divisional applications that may extend VDPP’s coverage.

What this case signals for the 3D display optics IP landscape
A fast settlement in E.D. Tex. over niche 3D spectacles patents suggests targeted licensing enforcement — not a one-off filing.
E.D. Tex. remains a preferred venue for patent assertion entities
VDPP filed in the Eastern District of Texas — specifically before Judge Gilstrap, one of the most experienced patent judges in the country. This venue choice is a deliberate signal: plaintiffs with licensing-focused strategies consistently favour E.D. Tex. for its scheduling efficiency and plaintiff-friendly reputation. Companies selling consumer electronics nationally should anticipate this forum.
Swift settlements indicate licensing economics drove resolution
A 174-day resolution with mutual cost-bearing is strongly consistent with a licensing payment rather than a hard-fought defence win. When PAEs settle this quickly, it typically suggests the defendant calculated that settlement cost was lower than litigation cost — a calculus that applies equally to any other retailer in the 3D eyewear distribution chain.
VDPP v Best — key questions answered
VDPP asserted two patents: US10021380B1 (App. No. US15/907614) and US9948922B2 (App. No. US15/683623). Both cover technology related to faster state-transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable-tint materials — a form of consumer 3D eyewear optical filtering technology.
The case was resolved by a joint motion to dismiss with prejudice, entered August 29, 2024, confirming the parties had settled. Dismissal with prejudice permanently bars VDPP from re-filing the same claims against Best Buy. The settlement terms are confidential; no merits determination on validity or infringement was issued by the court.
The Eastern District of Texas, and specifically Judge Rodney Gilstrap’s docket, is a historically favoured venue for patent assertion entities due to its established patent litigation procedures, experienced bench, and scheduling practices. Filing there is consistent with a licensing-focused enforcement strategy targeting large consumer electronics retailers.
The order specified that each party bears its own costs and fees — meaning no cost-shifting under Rule 54 or 35 U.S.C. § 285 was awarded. This is a neutral outcome on costs and is typical in agreed settlements. It does not signal that either side was found to have litigated in bad faith or that the case was exceptional.
Yes. The dismissal with prejudice only precludes VDPP from reasserting these patents against Best Buy. The patents themselves were never adjudicated invalid or unenforceable, and VDPP retains the right to assert them against other parties. Companies in the 3D eyewear or variable-tint display accessories space should treat both patents as active enforcement risks.
