Pavo Solutions v. Lexar International — Settlement in Principle After 134 Days
Pavo Solutions, LLC filed a patent infringement action against Lexar International and its Longsys parent entities in California’s Central District, asserting US6926544B2 — a rotatable USB connector patent — against 11 JumpDrive products. The parties reached a settlement in principle within 134 days, staying all proceedings before any substantive ruling.
Swift settlement in the rotatable USB flash drive IP space
On August 21, 2023, Pavo Solutions, LLC filed a patent infringement complaint in the Central District of California against Lexar International, Longsys Electronics Limited, and Shenzhen Longsys Electronics Co., Ltd. — the latter two being related Longsys entities that manufacture and distribute Lexar-branded products. The sole patent asserted was US6926544B2, which covers rotatable USB connector technology. The accused products encompassed eleven JumpDrive lines, including the TwistTurn2, TwistTurn, M36, M36 Pro, S33, S35, S37, and several Dual Drive variants, all of which incorporate a pivoting or rotating USB form factor.
Before any substantive motions or trial-readiness milestones were reached, the parties filed a Joint Motion to Stay All Deadlines and Notice of Settlement in Principle on or around January 2, 2024. The court granted the motion for good cause, staying all proceedings — including discovery and pending deadlines — through January 15, 2024. The case closed on January 2, 2024. Because the basis of termination is recorded as ‘Case Stayed’ following a settlement in principle, the precise final settlement terms, any licensing arrangement, and any financial consideration remain undisclosed in the public record.
Resolution in 134 days is notably swift for a multi-defendant patent infringement action, suggesting the parties may have had pre-litigation licensing discussions or that Lexar and the Longsys entities assessed early exposure and chose to negotiate rather than incur the cost of Markman proceedings or summary judgment practice. The involvement of both a Hong Kong-registered entity (Longsys Electronics Limited) and a Shenzhen-incorporated manufacturer (Shenzhen Longsys Electronics Co., Ltd.) alongside Lexar International as the brand-facing defendant is consistent with a supply-chain enforcement strategy. What drove the specific settlement figure — and whether a license to US6926544B2 was granted — is not determinable from the public record.

134 days — faster than the majority of patent infringement cases reaching trial
Settlement in principle: what the stay order reveals and what it does not
A joint stay motion — not a formal dismissal order
The case did not close via a Rule 41 dismissal. Instead, the parties jointly moved to stay all deadlines on notice of a settlement in principle. The court granted the stay through January 15, 2024. This mechanism is common when final settlement documentation — such as a license agreement or release — has been agreed in substance but not yet executed. It preserves the court’s jurisdiction until papers are filed.
Settlement in principleFinancial terms and licensing scope are not public
A settlement in principle provides no public indication of monetary consideration, royalty rates, or whether Lexar received a licence to US6926544B2 or a full release. The public record is silent on all financial and licensing terms. The absence of a costs order further means neither party can be inferred to have ‘won’ or ‘lost’ — the resolution is best characterised as a negotiated commercial outcome.
Confidential termsNaming the Longsys supply chain entities alongside Lexar
Pavo Solutions named not just Lexar International but also Longsys Electronics Limited and Shenzhen Longsys Electronics Co., Ltd. — the Hong Kong and Shenzhen entities in the manufacturing chain. This supply-chain enforcement approach is consistent with strategies designed to pressure both the brand owner and the manufacturer simultaneously, reducing the risk that a brand entity restructures to avoid liability.
Supply-chain enforcement134 days to settlement — well ahead of Markman
Resolution before any claim construction hearing or significant motion practice is notable. In the Central District of California, Markman hearings typically occur 12–18 months after filing. Settling in 134 days suggests either pre-existing licensing dialogue, a rapid commercial assessment by the defendants, or significant litigation cost pressure. No prior relationship or licensing history is determinable from the public record.

Stipulation of dismissal — official text
The court’s order granting the joint stay does not constitute a merits ruling. Its operative effect was solely procedural: suspending all discovery and deadlines to allow the parties to finalise settlement documentation. The phrase ‘settlement in principle’ confirms mutual agreement on material terms but stops short of a binding executed agreement. Neither validity nor infringement of US6926544B2 was adjudicated, leaving the patent’s enforceability fully intact for future proceedings against other parties.
US6926544B2 — Rotatable USB Connector Technology
US6926544B2 covers a rotatable or pivoting USB connector design — the mechanical interface that allows a USB plug to rotate relative to its housing, protecting the connector when not in use and enabling compact storage. The patent was filed under application number US10/346105. This class of design is central to the ‘swivel’ and ‘twist-turn’ form factors that became commercially dominant in portable flash drives. The technology addresses a practical durability and form-factor problem: protecting exposed USB pins while enabling a compact, capless device.
For the flash storage sector, rotatable USB connectors became a differentiating design feature — Lexar’s entire JumpDrive TwistTurn and swivel product lines depend on this mechanical architecture. A patent covering this mechanism therefore has broad potential applicability across the consumer USB flash market. The assertion against 11 distinct JumpDrive SKUs signals that Pavo Solutions views the patent’s claim scope as covering a wide range of commercial implementations, not just a single product design.
Should you run an FTO analysis against US6926544B2?
Any company currently selling, manufacturing, or designing rotatable, swivel, pivot, or twist-turn USB flash drives — or USB accessories with a rotating connector element — should assess their exposure to US6926544B2. The Lexar settlement without a public merits ruling means the patent’s claims remain unconstrued and potentially enforceable. OEMs, private-label flash brands, and USB peripheral makers are all within the logical scope of future enforcement.
PatSnap Eureka’s FTO Search Agent allows product and IP teams to map the claims of US6926544B2 against their specific connector designs, identify relevant prior art, and monitor for continuation or family patents that may extend Pavo’s IP position. Setting a claim-change alert on this patent family is advisable given the demonstrated willingness to enforce and the absence of any invalidating ruling in this proceeding.

What this case signals for the USB flash storage IP landscape
A single patent drove a rapid multi-defendant settlement. The pattern matters for any company selling rotatable or pivoting USB products.
US6926544B2 has demonstrated licensing leverage against major flash brands
The swift settlement — before any Markman ruling — suggests Lexar and the Longsys entities assessed the patent as a credible threat. Any company selling rotatable, pivoting, or swivel-type USB connectors should treat this patent as an active enforcement asset and consider whether their products fall within its claims.
Supply-chain naming strategy adds pressure on manufacturers, not just brands
By naming Shenzhen Longsys Electronics as a co-defendant alongside the brand-facing Lexar entity, Pavo Solutions created liability exposure at the manufacturing level. OEMs and contract manufacturers in the USB flash storage supply chain should assess their own exposure, not rely on brand-owner indemnities alone.
Pavo v Lexar — key questions answered
Pavo Solutions asserted US6926544B2, a patent covering rotatable USB connector technology. The accused products were eleven Lexar JumpDrive flash drives incorporating pivoting or swivel USB form factors, including the TwistTurn2, TwistTurn, M36, S33, S35, S37, and several Dual Drive variants.
The case closed on January 2, 2024, after the parties filed a Joint Motion to Stay All Deadlines and Notice of Settlement in Principle. The court granted the stay through January 15, 2024. No merits ruling was issued. Financial terms and licensing arrangements are not disclosed in the public record.
Shenzhen Longsys Electronics Co., Ltd. and Longsys Electronics Limited are entities in the manufacturing and distribution chain behind Lexar-branded products. Naming them alongside Lexar International is consistent with a supply-chain enforcement strategy that creates patent infringement liability at the manufacturer level, not solely at the brand or retail entity level.
No validity determination was made. The case settled in principle before any Markman claim construction hearing or summary judgment motion was heard. US6926544B2 remains unchallenged and presumptively valid based on its USPTO grant. The settlement does not constitute any admission regarding validity or infringement.
The case resolved in 134 days from filing to close — notably faster than the median patent case in the Central District of California, where Markman hearings alone typically occur 12–18 months post-filing. Pre-Markman resolution of this kind typically suggests pre-existing licensing dialogue, strong commercial risk assessment by defendants, or significant cost-driven settlement pressure.
