Gerardi v. Walmart: Dog Collar Design Patent Dismissed With Prejudice
Individual patent holder Katlyn Gerardi sued retail giant Walmart, Inc. in the Eastern District of Texas alleging infringement of USD1002119S, a design patent covering a dog collar. The case ended in a joint dismissal with prejudice after 160 days, with each party bearing its own costs — a resolution that forecloses any future refiling of the same claims.
Design patent assertion against Walmart ends in permanent dismissal
On July 16, 2025, individual inventor Katlyn Gerardi filed an infringement action against Walmart, Inc. in the U.S. District Court for the Eastern District of Texas before Judge Rodney Gilstrap, asserting design patent USD1002119S (application no. US29/876311), which covers the ornamental design of a dog collar. Gerardi was represented by Rabicoff Law LLC, a firm known for asserting patents held by individual inventors against large retailers.
The case concluded on December 23, 2025, when both parties filed a Joint Stipulation of Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Judge Gilstrap accepted the stipulation, dismissed all claims with prejudice, and ordered each party to bear its own costs and fees. A dismissal with prejudice is a final adjudication on the merits as a matter of law — Gerardi cannot refile the same design patent claims against Walmart arising from the same accused products.
The 160-day duration from filing to closure is consistent with a negotiated resolution reached before significant litigation milestones such as claim construction or discovery disputes. The mutual cost-bearing arrangement suggests neither party extracted a clear financial concession, though the public record does not disclose whether any confidential settlement payment accompanied the stipulation. The with-prejudice nature of the dismissal is the commercially significant element: it extinguishes Gerardi’s right to reassert these claims against Walmart.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii): permanent exit by mutual agreement
A joint stipulation of dismissal under Rule 41(a)(1)(A)(ii) requires consent from all parties and takes effect immediately upon filing — no court order is technically required, though Judge Gilstrap formally acknowledged and accepted it here. The ‘with prejudice’ designation is dispositive: it operates as a final judgment on the merits, permanently barring Gerardi from reasserting USD1002119S against Walmart for the same accused products.
Permanent claims barGerardi’s design patent rights against Walmart are extinguished
A with-prejudice dismissal is the strongest closing mechanism available short of a full judgment. Gerardi retains ownership of USD1002119S and may theoretically enforce it against other parties, but the claims against Walmart are permanently resolved. The own-costs arrangement means Gerardi bears all plaintiff-side litigation expenses with no court-ordered recovery. Whether any confidential payment was exchanged is not disclosed in the public record.
Patent survives; Walmart claims goneWalmart secures permanent protection from this specific design claim
Walmart obtains a clean exit: the with-prejudice dismissal acts as a preclusion shield against any future lawsuit by Gerardi on USD1002119S for the same accused dog collar products. Findlay Craft PC’s representation is consistent with Walmart’s standard approach of engaging specialist IP defence counsel in E.D. Texas design patent matters. Each party bearing its own costs is a neutral cost outcome for Walmart.
Preclusion shield securedDesign patent risk for retailers: individual inventors, mass-market products
This case is consistent with a broader pattern of individual design patent holders asserting ornamental design rights against large retailers in the Eastern District of Texas. Design patents on consumer products such as pet accessories present meaningful risk for retailers who source goods from multiple suppliers. The swift resolution here — under 6 months — suggests Walmart assessed the commercial cost of continued litigation against the cost of resolution, a calculus common to high-volume IP defence strategies.

Official order — verbatim text
The dismissal order’s language — ‘ACCEPTS AND ACKNOWLEDGES’ the stipulation and formally ‘DISMISSED WITH PREJUDICE’ — is standard E.D. Texas practice for Rule 41(a)(1)(A)(ii) joint stipulations. The court adds operative force by directing the Clerk to close the case. The ‘DENIED AS MOOT’ language on pending relief confirms no substantive motions were resolved on the merits, consistent with a pre-merits resolution. The own-costs order is neutral and does not signal which party held the stronger litigation position.
USD1002119S — Ornamental design for a dog collar
USD1002119S (application no. US29/876311) is a U.S. design patent protecting the ornamental appearance of a dog collar. Design patents under 35 U.S.C. § 171 protect the way an article looks, not how it functions — claim scope is defined entirely by the patent’s drawings. The ‘USD’ prefix designates a design patent, and the single claim is generally the phrase ‘the ornamental design for [the article], as shown and described.’ Protection typically lasts 15 years from grant under current U.S. law.
Design patents on everyday consumer goods such as pet accessories have become a meaningful enforcement tool because they are relatively inexpensive to obtain, their scope is visually assessed, and they can be asserted against retailers as well as manufacturers. For Walmart, sourcing a dog collar from a supplier whose design resembles a protected ornamental design creates direct infringement exposure at the retail level — a structural risk that applies equally to any large-format retailer carrying pet accessories from multiple third-party vendors.
Should your product team run an FTO against USD1002119S?
Any retailer, private-label brand, or pet accessory manufacturer selling dog collars in the U.S. market should assess whether their product’s ornamental design falls within the scope of USD1002119S. Design patent infringement is determined by the ‘ordinary observer’ test — whether an ordinary purchaser, familiar with the prior art, would be deceived into thinking the accused product is the same as the patented design. Given that this patent was asserted against one of the world’s largest retailers, the risk threshold for smaller operators is not trivially lower.
PatSnap Eureka’s FTO Search Agent enables product and IP teams to rapidly map ornamental design patent landscapes in the pet accessories category. By combining image-based design search with prosecution history analysis and citation mapping, Eureka helps you identify blocking design rights, assess scope, and document clearance decisions — before a product launches or a purchase order is placed with a supplier whose designs may already be under challenge.

What this case signals for the retail and consumer goods IP landscape
Individual design patent assertions against major retailers in E.D. Texas continue to be commercially viable pressure tools — even when quickly resolved.
E.D. Texas remains a preferred venue for individual design patent holders
Judge Gilstrap’s docket in the Eastern District of Texas continues to attract individual inventor design patent cases against large retailers. The filing-to-close timeline of 160 days is consistent with cases resolved before substantive motion practice, suggesting the venue itself creates settlement pressure on defendants facing the cost and risk of full E.D. Texas litigation.
With-prejudice dismissals protect defendants — but don’t invalidate the patent
USD1002119S remains a live, enforceable design patent. The dismissal with prejudice only bars claims against Walmart. Other retailers or distributors selling the same or similar dog collar designs remain exposed. Companies in adjacent retail positions — particularly those sourcing from the same suppliers as Walmart — should note the patent’s continued enforceability.
Gerardi v Walmart — key questions answered
The dismissal with prejudice means Katlyn Gerardi’s patent infringement claims against Walmart are permanently extinguished. She cannot refile the same claims based on USD1002119S against Walmart for the accused dog collar products. The patent itself remains enforceable against other parties.
The asserted patent is USD1002119S (application no. US29/876311), a U.S. design patent covering the ornamental design of a dog collar. Design patents protect how an article looks, not its function, and their scope is defined by the patent’s drawings under 35 U.S.C. § 171.
The Eastern District of Texas, particularly before Judge Rodney Gilstrap, is a historically popular venue for patent infringement cases due to its procedural rules and docket management. Individual inventor plaintiffs and smaller patent holders frequently file in E.D. Texas against national retailers with broad commercial presence, which typically satisfies venue requirements.
The public record does not disclose any settlement payment. The joint stipulation orders each party to bear its own costs and fees, but confidential financial terms — if any were agreed — would not appear in court filings. The with-prejudice dismissal is consistent with either a paid settlement or a no-payment resolution.
Yes. The with-prejudice dismissal in case 2:25-cv-00718 only bars Gerardi’s claims against Walmart specifically. USD1002119S remains a live, enforceable design patent. Gerardi retains the right to assert it against other retailers, distributors, or manufacturers selling dog collar designs that fall within the patent’s ornamental scope.
