Zhengzhoukangpeiningkeji v. Smythe: Footrest Design Patent Case Dismissed Without Prejudice
A Chinese design patent holder brought an infringement action in the Northern District of Illinois against James Smythe over a footrest covered by design patent USD0915790S. After the plaintiff failed to serve the defendant or respond to court orders, the case was dismissed without prejudice in just 125 days — leaving the door open for refiling.
Footrest Design Patent Action Dies on Service Failure — Not the Merits
On June 17, 2025, Zhengzhoukangpeiningkeji, a Chinese technology company, filed a patent infringement action in the U.S. District Court for the Northern District of Illinois against individual defendant James Smythe. The suit centred on design patent USD0915790S (application number US29/680159), which covers the ornamental design of a footrest product. The case was assigned to Judge April M. Perry.
The case never advanced beyond its earliest procedural stage. By September 30, 2025, the court issued an order directing the plaintiff to file a status report by October 10, 2025, explaining whether the defendant had been served and, if not, why the case should not be dismissed for failure to timely serve. The plaintiff filed nothing in response. On October 20, 2025, Judge Perry dismissed the matter without prejudice for failure to prosecute and failure to timely serve the defendant, terminating the civil case.
The 125-day case lifecycle is notable for its brevity, but the resolution reflects procedural default rather than any substantive evaluation of the patent or alleged infringement. The public record does not reveal why the plaintiff failed to serve Smythe or respond to the court’s order — possible explanations include difficulty locating the defendant, settlement discussions outside the docket, or a decision to abandon this particular action. Because the dismissal is without prejudice, Zhengzhoukangpeiningkeji retains the right to refile.

Dismissed without prejudice: what this outcome means for both parties
Dismissed for failure to prosecute and failure to timely serve
Under Federal Rule of Civil Procedure 4(m), a plaintiff must serve each defendant within 90 days of filing. Courts may dismiss an action without prejudice when a plaintiff fails to meet this obligation. Here, the court gave the plaintiff a final opportunity to explain non-service via a status report; the plaintiff’s silence left the court no alternative but to dismiss the action for failure to prosecute.
FRCP Rule 4(m) — service deadlineWithout prejudice: the case can be refiled — within limits
A dismissal without prejudice does not adjudicate the merits and does not bar the plaintiff from refiling. However, the plaintiff must still comply with applicable statutes of limitations and ensure proper service in any renewed action. This is distinct from a dismissal with prejudice, which would permanently extinguish the claims. The public record here confirms the without-prejudice characterisation expressly in the basis of termination.
Refiling permittedSmythe faces no judgment — but infringement claims remain unresolved
James Smythe obtains a practical reprieve: no infringement finding, no injunction, and no damages award. However, because the dismissal is without prejudice and no merits determination was made, the underlying design patent USD0915790S remains valid and enforceable. Smythe cannot rely on this dismissal as a defence if the plaintiff refiles or pursues the claim through another avenue.
No merits adjudicationDesign patent for footrest remains live enforcement risk
The dismissal leaves USD0915790S fully intact with no invalidity ruling and no exhaustion of claims. Companies and individuals selling footrest products that may implicate this design should not treat this dismissal as clearing the patent. The plaintiff — or a future assignee — retains enforcement rights. This outcome is a procedural reset, not a commercial clearance.

Official order — verbatim text
The court’s dismissal language is unambiguous: the action was terminated for failure to prosecute and failure to timely serve the defendant, not on any substantive patent law ground. The without-prejudice designation is legally significant — it preserves the plaintiff’s right to refile and explicitly forecloses any argument by the defendant that the claims have been extinguished. No merits findings were made regarding infringement, validity, or claim scope of USD0915790S, meaning the patent’s enforceability is entirely unchanged by this proceeding.
USD0915790S — Ornamental Design for a Footrest
USD0915790S, filed under application number US29/680159, is a U.S. design patent protecting the ornamental appearance of a footrest. Design patents under 35 U.S.C. § 171 cover the novel, ornamental characteristics of a manufactured article — in this case, the visual configuration of a footrest product. Design patents have a term of 15 years from grant and are infringed when an ordinary observer would find the accused product substantially similar to the patented design.
The footrest category is commercially active, with significant import volume from Chinese manufacturers to U.S. e-commerce channels. A U.S. design patent in this space gives the holder meaningful leverage against Amazon sellers and importers of visually similar products, without needing to prove functional novelty. The patent’s continued validity following this procedural dismissal means it remains a live commercial risk for any market participant whose products resemble the protected design.
Should you run an FTO analysis against USD0915790S?
Any company manufacturing, importing, or selling footrest products — particularly through U.S. e-commerce platforms — should assess exposure to USD0915790S. Design patent infringement is judged by the ordinary observer test, making visual similarity the key risk factor. The fact that this case was dismissed without prejudice means the patent has not been adjudicated and the holder retains full enforcement rights. R&D and product teams should document design-arounds and maintain records of independent design choices.

What this case signals for design patent enforcement in U.S. district courts
A failure-to-prosecute dismissal carries different risk signals than a merits loss — and misreading it can be costly.
Procedural dismissals do not validate competing products
A without-prejudice dismissal provides zero legal cover for third parties. The footrest design patent USD0915790S remains enforceable. Manufacturers, importers, and online marketplace sellers in this product category should treat this outcome as a temporary pause in enforcement, not a green light.
Service failure patterns can signal broader enforcement strategy shifts
When a patent holder files and then fails to serve, it sometimes suggests a pivot — to a different defendant, a different jurisdiction, or an alternative enforcement mechanism such as ITC proceedings or Amazon brand registry actions. Monitoring the plaintiff’s subsequent filings is advisable for anyone operating in the footrest or related consumer goods design space.
Zhengzhoukangpeiningkejiyouxiangongsi v James — key questions answered
The case was dismissed without prejudice on October 20, 2025. Plaintiff Zhengzhoukangpeiningkeji filed a design patent infringement action against James Smythe in the Northern District of Illinois concerning footrest design patent USD0915790S but failed to serve the defendant or respond to a court order, resulting in dismissal for failure to prosecute.
No. The dismissal was without prejudice and based entirely on procedural grounds — failure to prosecute and failure to timely serve. No merits determination was made. Design patent USD0915790S remains valid and enforceable, and the plaintiff retains the right to bring a new infringement action against Smythe or other parties.
Yes. A dismissal without prejudice does not bar refiling. The plaintiff may bring a new action provided it falls within the applicable statute of limitations and proper service is effected. The public record does not indicate whether the plaintiff intends to refile or pursue the matter through alternative enforcement mechanisms.
USD0915790S (application US29/680159) protects the ornamental design — the visual appearance — of a footrest product. Under U.S. patent law, design patent infringement is assessed using the ordinary observer test: whether an ordinary observer would find the accused design substantially similar to the patented design. The patent does not cover functional aspects of the footrest.
A failure to prosecute dismissal signals that the plaintiff did not actively pursue the litigation — in this instance by failing to serve the defendant and by failing to respond to a court order. It results in termination without any ruling on infringement, validity, or damages. For third parties, it means the patent remains live with no prior art or invalidity findings on the record from this proceeding.
