Sidekick USA v. Van’s Enterprises: Infringement Dispute Ends in Dismissal With Prejudice
Sidekick USA, LLC filed a patent infringement action against Van’s Enterprises, Ltd. in the Northern District of Illinois, asserting US9028199B2. After 238 days of litigation, both parties jointly moved to dismiss all claims with prejudice, bringing the case to a final close.
Agreed Dismissal With Prejudice Closes N.D. Illinois Infringement Action
On April 11, 2025, Sidekick USA, LLC filed a patent infringement complaint against Van’s Enterprises, Ltd. in the United States District Court for the Northern District of Illinois, Case No. 1:25-cv-03963, before Judge Thomas M. Durkin. The action centred on US9028199B2 and alleged that Van’s engaged in contributory infringement or inducement in violation of Sidekick’s patent rights. The case was litigated through LeFevour Law LLC and ML LeFevour & Associates, Ltd. on the plaintiff’s side, with Chicago IP Law and Lesley A. Wallerstein, LLC representing Van’s.
The case closed on December 5, 2025, when Judge Durkin granted the parties’ agreed motion to dismiss all claims against Van’s with prejudice. A dismissal with prejudice is a final adjudication on the merits — Sidekick cannot refile the same infringement claims against Van’s based on the same patent and accused conduct. The agreed nature of the motion strongly suggests the parties reached a private resolution, though no public settlement terms have been disclosed.
The 238-day duration from filing to dismissal is consistent with early-stage resolution in N.D. Illinois, suggesting the parties negotiated before significant discovery or claim construction activity occurred. What drove the resolution — whether a licence, a product redesign by Van’s, or a simple commercial agreement — remains unknown from the public record. The with-prejudice designation, however, provides Sidekick no further avenue to pursue these specific claims against Van’s in federal court.

Dismissed with prejudice: what the agreed order means for both parties
Dismissal with prejudice is a final bar on refiling
A dismissal with prejudice under federal procedure operates as a final adjudication on the merits. Sidekick USA cannot refile the same patent infringement claims based on US9028199B2 against Van’s Enterprises for the same accused conduct. The agreed nature of the motion — signed off by both parties — distinguishes this from a contested dismissal and typically signals a negotiated resolution reached outside the court record.
No refiling permittedSidekick forfeits future claims against Van’s on this patent
By agreeing to a with-prejudice dismissal, Sidekick USA permanently surrenders the right to pursue these specific infringement claims against Van’s. This is a meaningful concession unless offset by an undisclosed licence fee, royalty arrangement, or Van’s agreement to cease the accused conduct. The public record does not reveal whether Sidekick received any commercial consideration in exchange for the dismissal.
Claims extinguishedVan’s Enterprises achieves full resolution of all asserted claims
Van’s Enterprises obtained dismissal of all claims with prejudice, providing permanent closure on this litigation. Whether that came at the cost of a licence payment, a product modification, or purely through legal defence is not disclosed. The with-prejudice outcome means Van’s faces no residual litigation risk from Sidekick on US9028199B2 for the conduct at issue, though Sidekick retains enforcement rights against other parties and for future conduct.
Full dismissal securedPrivate resolution leaves US9028199B2 enforcement posture intact
Because the case resolved without any public claim construction ruling or validity finding, US9028199B2 remains unchallenged on the merits. Sidekick retains the patent in full force and can pursue enforcement actions against other parties. Competitors and third parties operating in the same product space should note that the patent’s scope and validity have not been tested by a court, preserving Sidekick’s ability to assert it in future disputes.

Official order — verbatim text
The court’s order is narrow and procedural: it grants the parties’ agreed motion and dismisses all claims with prejudice, without any findings on infringement, invalidity, or claim scope. This phrasing confirms the resolution is entirely consensual — neither party obtained a judicial finding on the merits. For Van’s, the order provides clean finality. For third parties monitoring US9028199B2, the absence of any substantive ruling means the patent’s enforceability and claim scope remain fully open questions.
US9028199B2 — Patent at the Centre of the Sidekick v. Van’s Dispute
US9028199B2 was filed under application number US13/358143 and issued as a granted United States patent. The case alleged contributory infringement and inducement, suggesting the patent covers a product or method that Van’s Enterprises was accused of enabling third-party infringement of, rather than direct infringement alone. The dual-theory assertion — contributory and induced — is a common enforcement posture where the accused party supplies a component or instructions that facilitate another party’s use of the patented invention.
Because the litigation resolved without any public claim construction proceeding, the precise boundaries of US9028199B2’s claims have not been tested in court. This makes the patent a live enforcement risk for any competitor or supplier operating in the same product category as Van’s Enterprises. The patent holder, Sidekick USA, retains full enforcement rights and faces no estoppel from this litigation, preserving its ability to assert the patent against additional defendants.
Should your team run an FTO analysis against US9028199B2?
Any company manufacturing, supplying, or distributing products in the same category as those accused in the Sidekick v. Van’s action should treat US9028199B2 as an active enforcement risk. The with-prejudice dismissal did not produce a claim construction order or invalidity ruling — meaning no public judicial analysis limits or defines the patent’s scope. If your product overlaps with the accused conduct (contributory or induced infringement), an FTO review is warranted before commercialisation or expansion.
PatSnap Eureka’s FTO Search Agent allows R&D and legal teams to map the claim language of US9028199B2 against current product designs, identify prior art that could support an IPR or PGR challenge, and monitor Sidekick USA’s broader patent portfolio for related continuation or divisional applications. Early FTO analysis reduces downstream litigation exposure and supports proactive licensing negotiations before a complaint is filed.

What this case signals for the US9028199B2 IP enforcement landscape
An agreed with-prejudice dismissal after 238 days typically signals a private deal — but leaves the patent fully armed for future enforcement.
No merits ruling means US9028199B2 faces no estoppel from this case
Because the dismissal was agreed and non-merits, no claim construction or invalidity findings bind Sidekick. The patent exits this litigation with its enforceability fully intact. Third parties in the same product category cannot rely on this case as precedent to challenge the patent’s scope.
Agreed dismissals at this stage typically reflect undisclosed commercial terms
Joint motions to dismiss with prejudice filed before claim construction — as appears likely here given the 238-day timeline — consistently suggest a negotiated exit. Whether that involved a licence, a royalty, or an injunctive commitment by Van’s is unknown, but the permanence of the dismissal implies Sidekick received sufficient consideration.
Sidekick v Van’s — key questions answered
The dismissal with prejudice bars Sidekick from refiling the same infringement claims against Van’s based on US9028199B2 for the same conduct. However, it does not invalidate the patent, limit its claims, or prevent Sidekick from asserting it against other parties. The patent remains fully enforceable.
No merits determination was made. Both parties agreed to dismiss all claims with prejudice before any substantive rulings. The public record does not reveal whether Sidekick received a licence payment or other consideration, so characterising the outcome as a win or loss for either party is not supported by the available record.
The patent asserted was US9028199B2, filed under application number US13/358143. The complaint alleged contributory infringement and inducement. No claim construction or validity ruling was issued during the litigation.
238 days is consistent with a pre-claim-construction resolution in N.D. Illinois. The agreed nature of the dismissal motion suggests the parties negotiated a private resolution — potentially a licence or cessation of the accused conduct — before investing in full discovery or Markman proceedings. The specific terms are not public.
Not for the same conduct covered by the dismissed complaint. A with-prejudice dismissal operates as a final adjudication, barring Sidekick from bringing the same claims against Van’s again. If Van’s engaged in materially new infringing conduct after the dismissal, that could theoretically form the basis of a new action, but the dismissed claims are permanently resolved.
