Jezign Licensing v. Poshmark: Light-Up Boots Design Patent Dismissed With Prejudice
Jezign Licensing, LLC asserted design patent USD554848S — covering light-up boot designs including Sport Keene and Sport Krysten — against online fashion resale platform Poshmark, Inc. in the Northern District of California. The parties jointly dismissed the case with prejudice after 330 days, with each side bearing its own fees and costs.
Design Patent Assertion Against Poshmark Ends in Prejudicial Joint Dismissal
On January 15, 2024, Jezign Licensing, LLC filed a patent infringement action against Poshmark, Inc. in the U.S. District Court for the Northern District of California (Case No. 3:24-cv-00256), assigned to Judge Araceli Martinez-Olguin. The complaint centered on design patent USD554848S — a design patent covering ornamental features of light-up boots, with accused products identified as the Sport Keene and Sport Krysten styles listed on Poshmark’s resale marketplace.
The case closed on December 10, 2024, via a joint stipulation of dismissal with prejudice filed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The with-prejudice designation is legally significant: it operates as a final adjudication on the merits, permanently barring Jezign from reasserting the same claims against Poshmark based on the same patent. Both parties agreed to bear their own fees and costs, with no financial award recorded in the public docket.
The 330-day duration and the mutual cost-bearing arrangement are consistent with a negotiated resolution reached before significant litigation milestones such as claim construction or summary judgment. The public record does not disclose whether any licensing agreement, payment, or other commercial terms were reached between the parties — the dismissal stipulation itself is silent on underlying consideration. What drove the resolution, and whether Jezign obtained any commercial concession from Poshmark, remains unknown from the public record.

Dismissed with prejudice: what the joint stipulation means for both parties
FRCP 41(a)(1)(A)(ii): joint stipulation of dismissal with prejudice
A dismissal under Rule 41(a)(1)(A)(ii) requires the signatures of all parties who have appeared. When filed ‘with prejudice,’ it constitutes a final judgment on the merits under res judicata principles. Unlike a court-ordered dismissal, this was a fully consensual exit — both Jezign and Poshmark signed off, suggesting the litigation reached a point where neither party wished to continue.
Voluntary, bilateral, permanentJezign permanently barred from re-suing Poshmark on USD554848S
By agreeing to dismissal with prejudice, Jezign Licensing surrendered its right to bring the same design patent claims against Poshmark in any future proceeding. This is the maximum procedural concession a plaintiff can make. Whether Jezign received commercial consideration in exchange — such as a licensing fee or marketplace takedown — is not disclosed in the public record, but the with-prejudice term suggests the matter was fully resolved to both parties’ satisfaction.
No refiling permittedPoshmark achieves permanent closure on this design patent claim
Poshmark, defended by Goodwin Procter LLP, secured a with-prejudice dismissal — meaning Jezign’s USD554848S infringement claims are permanently extinguished as against Poshmark. The each-party-bears-own-costs arrangement avoids any fee exposure for Poshmark. Poshmark retains potential exposure to USD554848S claims in any future action involving different accused products or a different defendant, as the dismissal binds only these parties.
Full closure, no cost awardDesign patent risk persists for other resale platforms and footwear sellers
USD554848S remains an active, enforceable design patent. The dismissal with prejudice settles only the Poshmark dispute — Jezign retains the right to assert the same patent against other marketplaces, retailers, or direct sellers of light-up boot designs. Resale platforms and footwear brands listing similar ornamental designs should assess their exposure, particularly given Jezign’s apparent willingness to pursue litigation in the Northern District of California.

Official order — verbatim text
The stipulation invokes FRCP 41(a)(1)(A)(ii) — a consensual, bilateral dismissal mechanism requiring both parties’ signatures. The with-prejudice designation is the operative legal term: it forecloses any future action by Jezign against Poshmark on these specific claims, functioning as a final adjudication on the merits. The silence on underlying consideration is characteristic of confidential settlements; the public record neither confirms nor denies any payment or licensing arrangement.
USD554848S — Ornamental Design for Light-Up Boots
USD554848S (application number US29/217103) is a U.S. design patent protecting the ornamental appearance of light-up boots — footwear incorporating illuminated design elements. Design patents under 35 U.S.C. § 171 protect the novel, ornamental characteristics of an article of manufacture rather than functional features. The scope of protection is defined by the patent’s drawings, making visual similarity the central test in any infringement analysis under the ‘ordinary observer’ standard established in Egyptian Goddess v. Swisa.
Light-up footwear occupies a niche but commercially active segment of the fashion and novelty footwear market. Design patent enforcement in this category has escalated as licensing entities target both direct sellers and online marketplaces. USD554848S remains enforceable following this dismissal, presenting ongoing risk for any party listing, selling, or distributing footwear with ornamental designs substantially similar to the Sport Keene or Sport Krysten configurations. Competitors and marketplace operators should treat this patent as an active litigation asset.
Should you run an FTO analysis against USD554848S?
Any brand, retailer, or online marketplace active in the light-up or illuminated footwear category should assess their exposure to USD554848S. The patent’s ornamental scope extends to the specific visual configuration of the boot designs — but parties selling stylistically similar footwear or hosting such listings on a marketplace platform may fall within the ordinary observer test. Given Jezign’s demonstrated willingness to litigate in the Northern District of California, a proactive FTO review is warranted before launching or continuing to offer comparable designs.

What this case signals for design patent enforcement on resale platforms
Jezign’s action against Poshmark highlights growing design patent enforcement risk for peer-to-peer marketplaces hosting third-party product listings.
Resale marketplaces face design patent liability for listed third-party products
Jezign’s assertion against Poshmark — a platform where sellers list products rather than Poshmark itself manufacturing them — suggests patent holders are testing marketplace liability theories for design infringement. Platforms that host third-party product imagery and listings should audit their IP exposure policies, particularly for fashion and footwear categories.
With-prejudice dismissal without cost-shifting is a common negotiated endgame
The mutual cost-bearing arrangement is a hallmark of cases that settle commercially without a clear litigation winner. In design patent cases involving NPE plaintiffs, this pattern typically suggests the defendant either made a nuisance payment or the plaintiff concluded enforcement costs outweighed recovery prospects. Neither inference is confirmed by the public record.
Jezign v Poshmark — key questions answered
The case was jointly dismissed with prejudice on December 10, 2024, pursuant to FRCP 41(a)(1)(A)(ii). Each party agreed to bear its own fees and costs. The with-prejudice dismissal permanently bars Jezign from reasserting the same design patent claims against Poshmark.
Jezign asserted U.S. design patent USD554848S (application number US29/217103), which covers the ornamental design of light-up boots. The accused products were identified as the Sport Keene and Sport Krysten styles listed on the Poshmark platform.
A with-prejudice dismissal operates as a final judgment on the merits under res judicata principles. Jezign cannot refile the same design patent infringement claims against Poshmark in any court. However, USD554848S remains enforceable against other defendants not party to this dismissal.
The public record does not disclose any financial consideration. The joint stipulation states only that each party bears its own fees and costs. Whether a separate licensing agreement or commercial arrangement was reached remains unknown — this is common in confidential settlements structured around a stipulated dismissal.
Yes. The dismissal with prejudice binds only the parties to this action — Jezign Licensing and Poshmark. USD554848S remains an active, enforceable design patent. Jezign retains the right to assert it against other marketplaces, retailers, or manufacturers of similar light-up boot designs.
