Better Mouse Company v. Schedule A Defendants: Voluntary Dismissal After 174 Days
Better Mouse Company, LLC asserted US7532200B2 — a patent covering computer mice technology — against a Schedule A roster of defendants in the Northern District of Illinois. The plaintiff voluntarily dismissed the action without prejudice 174 days after filing, leaving the door open for future enforcement.
Mouse patent suit ends early — but without prejudice creates ongoing risk
Better Mouse Company, LLC filed Case No. 1:24-cv-09545 on 4 October 2024 in the U.S. District Court for the Northern District of Illinois, asserting infringement of US7532200B2 against an unnamed roster of defendants listed on Schedule A — a filing pattern common in multi-defendant e-commerce enforcement actions targeting sellers of allegedly infringing computer mice products.
On 27 March 2025, counsel filed a voluntary notice of dismissal pursuant to Fed. R. Civ. P. 41(a)(1)(A)(i), terminating the action without prejudice. Because dismissal occurred before the defendant served an answer or a motion for summary judgment, plaintiff was entitled to dismiss as of right — no court order was required. Critically, a without-prejudice dismissal does not extinguish the underlying patent claims.
The 174-day lifespan is consistent with Schedule A cases that resolve through early settlement or are withdrawn after defendants cannot be served or identified. The public record does not disclose whether any consideration was exchanged, whether service was completed, or what drove the withdrawal. The without-prejudice posture means Better Mouse Company could theoretically refile the same claims against the same or different defendants.

174 days from filing to voluntary dismissal — relatively swift for N.D. Illinois patent litigation
Voluntarily dismissed: what the Rule 41 filing means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, no court approval needed
Fed. R. Civ. P. 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order if filed before the opposing party serves an answer or a motion for summary judgment. This is a unilateral right — the court plays no role. It signals the case ended at the earliest procedural stage, with no substantive adjudication of the patent claims.
Pre-answer dismissalPublic record is silent on whether a settlement was reached
The notice specifies dismissal without prejudice, meaning Better Mouse Company retains the right to refile the same infringement claims. This is distinct from a with-prejudice dismissal, which would bar re-litigation. Whether the without-prejudice outcome reflects a private settlement, a failed service attempt, or a strategic withdrawal is not disclosed in the public docket.
Refiling risk remains openNo judgment entered — but defendants face ongoing exposure
Schedule A defendants received no formal judgment in their favour. While the immediate litigation burden is lifted, the without-prejudice dismissal means the same patent can be re-asserted at any time within the statute of limitations. Defendants who have not cleared their product lines against US7532200B2 remain commercially exposed to a refiled action.
No res judicata protectionSchedule A enforcement pattern: early exit is common, not definitive
Cases filed against Schedule A defendants in N.D. Illinois frequently resolve early — through settlement, TRO-driven asset freezes, or simple withdrawal. The swift lifecycle here is consistent with that pattern. Companies selling computer mice through online marketplaces should treat a voluntary dismissal without prejudice as a pause, not a conclusion, when assessing ongoing IP risk from this patent.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly states ‘without prejudice’ — language that carries material legal consequence. No merits ruling was issued, and no judgment was entered against any defendant. The without-prejudice designation preserves Better Mouse Company’s ability to refile within the applicable limitations period. This verdict phrasing offers no insight into claim validity or infringement scope; it reflects a procedural exit, not a substantive resolution.
US7532200B2 — Computer mice input device technology
US7532200B2, filed under application number US11/036127, is a granted U.S. utility patent covering technology in the computer mice product space — a sector characterised by high commercial volume and significant online marketplace distribution. The patent’s application filing date suggests it captures input device innovations from the mid-2000s era, a period of rapid development in ergonomic and functional mouse design.
From a competitive intelligence standpoint, this patent’s assertion against a Schedule A defendant roster signals that Better Mouse Company views it as commercially enforceable against mass-market sellers. For hardware OEMs, online marketplace sellers, and peripherals brands, US7532200B2 represents a live enforcement asset. The voluntary dismissal without prejudice does not diminish its strategic value to the plaintiff — and may indicate continued enforcement activity is planned.
Should you run an FTO against US7532200B2?
Any company designing, importing, distributing, or selling computer mice products in the U.S. market should consider whether their product architecture intersects with the claims of US7532200B2. The patent has been asserted in active litigation as recently as late 2024, and the without-prejudice dismissal means the risk window is still open. This applies particularly to online marketplace sellers, private-label hardware brands, and peripherals distributors sourcing products from overseas manufacturers.

What this case signals for the computer mice IP enforcement landscape
Schedule A patent enforcement in N.D. Illinois is a high-volume, fast-moving strategy — early exits are common but carry lasting risk.
Without-prejudice dismissal is not clearance — FTO still required
Sellers of computer mice products should not treat this dismissal as confirmation that US7532200B2 poses no risk. Better Mouse Company retains full ability to refile. Any company distributing or selling computer mice in the U.S. market should assess their exposure to the claims in this patent independently of the case outcome.
Schedule A filings signal broader enforcement intent beyond one defendant
The Schedule A naming convention is a deliberate litigation tool — one complaint covers dozens of sellers simultaneously. A voluntary dismissal against one Schedule A wave does not preclude a refiled action against the same or a wider defendant pool. IP counsel should monitor Better Mouse Company’s docket activity for re-filed actions.
Better v Partnerships — key questions answered
The plaintiff dismissed the case using Fed. R. Civ. P. 41(a)(1)(A)(i) before any defendant answered. ‘Without prejudice’ means no judgment was entered and Better Mouse Company retains the right to refile the same patent infringement claims against the same or different defendants within the applicable statute of limitations.
Better Mouse Company asserted US7532200B2 (application number US11/036127), a granted U.S. utility patent covering computer mice technology. The case was filed in the Northern District of Illinois on 4 October 2024 and voluntarily dismissed on 27 March 2025.
A Schedule A defendant refers to an unnamed list of defendants — typically online marketplace sellers — attached to the complaint rather than named in the case caption. This filing format is common in N.D. Illinois and allows plaintiffs to pursue multiple sellers simultaneously under a single docket number, often targeting e-commerce platforms selling allegedly infringing products.
No. The voluntary dismissal was made without prejudice and without any merits adjudication. No court ruled on the validity or infringement scope of US7532200B2. The patent remains in force, and Better Mouse Company retains full rights to enforce it in future proceedings.
Better Mouse Company, LLC was represented by attorney Nicholas Edward Najera of Ni Wang & Associates PLLC. No defendant counsel of record appears in the public docket, consistent with a case that resolved or was withdrawn before defendants formally appeared.
