Swissdigital v. Wenger: USB Backpack Patent Case Dismissed With Prejudice
Swissdigital USA filed suit against Wenger NA in the Western District of Texas, asserting two patents covering USB charging and ScanSmart backpack technology against a range of SwissGear products. The case ran for 949 days before being dismissed with prejudice, permanently closing Swissdigital's claims in this forum.
USB backpack patent claims permanently extinguished after 949 days
Swissdigital USA Co., Ltd., a Delaware LLC, filed suit on 30 April 2021 against Wenger NA in the Western District of Texas, asserting infringement of two U.S. patents — US10931138B2 and US10574071B2 — covering USB-integrated charging systems incorporated into laptop backpacks. The accused products comprised multiple SwissGear ScanSmart USB backpack lines sold via www.swissgear.com, including the 3670, 3672, 2760, and 3916 models, as well as an 18.5-inch TSA laptop backpack with USB power plug.
The case closed on 5 December 2023, with the recorded basis of termination being dismissal with prejudice. A dismissal with prejudice constitutes a final adjudication on the merits as a matter of procedural law, meaning Swissdigital is barred from re-asserting these same claims against Wenger on these patents in any subsequent federal action. The specific terms and circumstances that led to this disposition are not disclosed in the available public record.
The 949-day duration — spanning nearly two and a half years — suggests the case progressed through substantive litigation phases before resolution. What drove the parties to this terminal outcome, whether through motion practice, settlement negotiations, or other procedural developments, is not apparent from the public docket record. Competitors and IP practitioners in the wearable-tech accessories space should note that the permanent bar on re-filing removes this specific enforcement threat from the landscape.

US10931138B2 & US10574071B2 — USB-integrated smart backpack charging systems
If your company designs, manufactures, imports, or retails backpacks or carry systems incorporating USB charging ports, embedded power banks, or smart-compartment features, these two Swissdigital patents are directly relevant to your FTO analysis. The fact that no claim construction or invalidity ruling was issued in this case means the claim boundaries remain untested in court — a materially different risk profile from patents that have survived inter partes review or Markman proceedings.
Official order — verbatim text
The amended complaint sets out a straightforward patent infringement action under 35 U.S.C. § 271, identifying specific SwissGear USB ScanSmart backpack SKUs as the accused products. The recorded basis of termination — dismissal with prejudice — means the litigation ended with a permanent bar on re-assertion, but the specific procedural mechanism and any underlying terms are not disclosed in the available public record.
Dismissed with prejudice: what the final bar means for both parties
Dismissal with prejudice is a final, merits-equivalent bar
A dismissal with prejudice operates as a final adjudication on the merits under federal procedural rules. It extinguishes the plaintiff's right to re-file the same claims in any subsequent federal action. Unlike a dismissal without prejudice, it cannot be undone by re-filing — the claims are permanently closed. The specific procedural vehicle that produced this dismissal is not disclosed in the available record.
Permanent bar on re-filingSwissdigital loses its right to re-assert these claims against Wenger
The dismissal with prejudice forecloses Swissdigital from bringing the same US10931138B2 and US10574071B2 infringement claims against Wenger NA in a subsequent federal suit. The underlying patents remain in force — Swissdigital may still assert them against other parties — but this particular enforcement avenue against Wenger is permanently closed. Any future action against Wenger on these patents would face a res judicata challenge.
Claims against Wenger permanently barredWenger secures a permanent shield on these asserted patents
For Wenger NA and its SwissGear USB ScanSmart product lines, the dismissal with prejudice provides the strongest available litigation closure short of a merits judgment of non-infringement or invalidity. The accused products — including the 3670, 3672, 2760, and 3916 USB backpack models — are no longer exposed to Swissdigital's infringement claims under these two patents. The specific terms of any underlying agreement are not disclosed in the public record.
SwissGear products cleared of these claimsUSB backpack IP enforcement landscape shifts after this closure
The permanent dismissal removes a live infringement threat from the USB-integrated laptop backpack segment. Competitors and new entrants in the ScanSmart-style accessory market should note that Swissdigital's patents US10931138B2 and US10574071B2 remain active and enforceable against third parties. Any company designing or selling USB-integrated backpacks should assess exposure to these patents independently, as only Wenger's products benefit from this dismissal's preclusive effect.

R&D signals in the USB-integrated smart bag technology space
Forward-looking patent and R&D intelligence derived from Swissdigital's assertion of USB charging backpack patents against Wenger's SwissGear product lines.
Swissdigital's USB bag patent family signals a multi-generation enforcement posture
With application dates spanning 2015 to 2020, Swissdigital's two asserted patents suggest a continuation-aware prosecution strategy designed to keep claims alive as USB-integrated carry products evolved. Portfolio watchers should check for further pending continuations that may cover USB-C, wireless charging, or LED-integrated smart bag features — areas where SwissGear and competitors are actively developing products.
Continuation riskFiling activity in USB-integrated carry systems is accelerating
The ScanSmart and USB-port-integrated backpack category has attracted growing patent activity from consumer electronics accessory brands, luggage manufacturers, and electronics OEMs. Filing trends around embedded power delivery, pass-through charging, and TSA-compliant smart compartments suggest the technology is entering a consolidation phase where early filers — like Swissdigital — hold structural IP advantages over later entrants.
IP consolidation phaseWenger and Victorinox group IP activity in smart travel accessories
Wenger NA's defence of the SwissGear USB ScanSmart range — supported by Reichman Jorgensen Lehman & Feldberg LLP — signals a well-resourced IP defensive posture. Monitoring Wenger's and its Swiss parent's own patent filings in smart luggage, RFID, and integrated charging may reveal where the SwissGear product roadmap is heading and whether offensive IP positions are being built.
Defensive IP postureWireless charging and USB-C integration in bags remains lightly patented
The asserted patents focus on USB-A port integration and ScanSmart-style compartment design. Adjacent claim space around USB-C power delivery, Qi wireless charging pads embedded in bag panels, and IoT-enabled smart bag sensors may represent white space where new IP positions can be established. R&D teams developing next-generation travel accessories should assess claim freedom and filing opportunity in these adjacent domains.

What this case signals for the USB-integrated accessories IP landscape
A 949-day W.D. Texas infringement case ending with prejudice reshapes enforcement calculus for smart bag patent holders and product competitors alike.
Swissdigital's patents remain enforceable — only Wenger benefits from preclusion
US10931138B2 and US10574071B2 are still active. The dismissal with prejudice bars claims only against Wenger NA. Any third-party USB backpack manufacturer or retailer remains fully exposed to assertion. IP teams at competing accessory brands should treat these patents as live enforcement risk and conduct independent FTO analysis.
W.D. Texas remains a strategically chosen venue for accessory-tech patent disputes
Filing in the Western District of Texas — a preferred plaintiff venue — signals that Swissdigital pursued an aggressive enforcement posture. The 949-day duration before dismissal with prejudice suggests substantive litigation activity. Future plaintiffs asserting USB or smart-bag patents in this district should anticipate well-resourced defence from Swiss-affiliated consumer goods defendants.
Swissdigital v Wenger — key questions answered
Swissdigital USA Co., Ltd. asserted two patents: US10931138B2 (application US16/838059) and US10574071B2 (application US14/836104). Both patents relate to USB-integrated charging systems incorporated into laptop backpacks. The accused products were multiple SwissGear ScanSmart USB backpack models sold via www.swissgear.com.
The case was dismissed with prejudice on 5 December 2023, approximately 949 days after filing. A dismissal with prejudice permanently bars Swissdigital from re-asserting the same claims against Wenger in a subsequent federal action. The specific terms and procedural mechanism behind the dismissal are not disclosed in the available public record.
Yes. A dismissal with prejudice resolves only the claims between Swissdigital and Wenger NA. The underlying patents US10931138B2 and US10574071B2 remain in force and can be asserted against other parties. Only Wenger and its SwissGear products benefit from the preclusive effect of this specific dismissal.
The accused products identified in the amended complaint include the SwissGear 3670 USB ScanSmart Laptop Backpack, SwissGear 3672 USB ScanSmart Laptop Backpack, SwissGear 18.5-inch ScanSmart TSA Laptop and USB Power Plug Backpack, SwissGear 2760 USB ScanSmart Laptop Backpack with LED Light, and SwissGear 3916 USB ScanSmart Laptop Backpack with LED Light, all sold via www.swissgear.com.
The complaint does not explain the specific venue rationale in the available record. The Western District of Texas — particularly the Waco division — has been a frequently chosen forum for patent infringement actions due to its established patent docket and historically plaintiff-friendly case management. The specific jurisdictional basis asserted by Swissdigital is not detailed in the available public record.
