Big Will Enterprises v. Earnix: 5-Patent Driver Monitoring Suit Dismissed With Prejudice in 35 Days
Big Will Enterprises filed a five-patent infringement action against insurtech firm Earnix in the Eastern District of Texas, asserting patents covering its Drive-It driver activity monitoring system. The case was dismissed with prejudice at the plaintiff’s own request just 35 days after filing — before Earnix had entered any appearance.
Five-patent driver monitoring suit exits E.D. Texas in under six weeks
On January 25, 2024, Big Will Enterprises, Inc. filed a patent infringement action against Earnix, Inc. in the Eastern District of Texas (Case No. 4:24-cv-00069) before Chief Judge Amos L. Mazzant. The complaint asserted five United States patents — US9049558B2, US8452273B1, US10521846B2, US8737951B2, and US8559914B2 — all directed at the Drive-It system, a platform using wireless communication devices to monitor human activities while driving.
On February 29, 2024, just 35 days after filing, Big Will filed a Notice of Dismissal with Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted the notice and formally ordered the case dismissed with prejudice, directing each party to bear its own attorneys’ fees and costs. Dismissal with prejudice permanently extinguishes the plaintiff’s right to bring the same claims against Earnix on these five patents.
A 35-day lifespan — closing before the defendant appears to have filed any formal response — is exceptionally short and suggests the parties may have reached a private resolution, or that Big Will concluded its claims were not viable to pursue. The public record does not disclose any settlement terms or licensing arrangement. The with-prejudice designation is notable: it forecloses any future action by Big Will against Earnix on these specific patents.

Dismissed with prejudice: what the Rule 41 notice means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral dismissal right
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. Big Will exercised this right here. The court’s order formalised the dismissal but the procedural vehicle gave Big Will full control over the exit — no defendant consent was required.
Plaintiff-initiated exitWith prejudice: Big Will’s claims against Earnix are permanently barred
A dismissal with prejudice operates as a final adjudication on the merits. Big Will cannot refile these five patent claims against Earnix in any federal court. This is a stronger closure than a without-prejudice dismissal, which would permit refiling. The with-prejudice election may reflect a negotiated arrangement or an acknowledgment that the claims could not withstand scrutiny — the public record does not clarify which.
Permanent bar on refilingEach party bears its own costs — no fee-shifting ordered
The court ordered each party to bear its own attorneys’ fees and costs. In dismissed patent cases, courts sometimes award fees to defendants under 35 U.S.C. § 285 if the case is deemed exceptional. No such finding was made here, consistent with the early, uncontested exit. For Earnix, this means no cost recovery despite the litigation burden.
No § 285 fee award35-day lifespan: what an ultra-short case typically signals
Cases dismissed before any defendant filing typically indicate one of three scenarios: a private settlement or licensing deal reached immediately post-complaint; a demand letter strategy where filing itself was the leverage; or plaintiff counsel concluding infringement could not be established. None of these can be confirmed from the public record, but the with-prejudice designation and absence of any Earnix filing are consistent with a swift, negotiated exit.

Stipulation of dismissal — official text
The court’s order reflects a straightforward acceptance of Big Will’s Rule 41(a)(1)(A)(i) notice, requiring no substantive analysis of the merits. The with-prejudice designation — chosen by the plaintiff, not imposed by the court — is the operative legal fact. It permanently bars Big Will from reasserting these five patents against Earnix. The mutual cost-bearing order suggests no party sought or obtained a fee advantage, leaving the commercial terms of any underlying arrangement entirely private.
US9049558B2 and four related Drive-It driver monitoring patents
The five asserted patents — US9049558B2, US8452273B1, US10521846B2, US8737951B2, and US8559914B2 — collectively cover the Drive-It system, a platform that uses wireless communication devices (WCDs) to monitor human activities while driving. Application dates span from approximately 2009 (US12/354927) through 2015 (US14/606421), indicating a sustained prosecution strategy across multiple continuation and related filings. The technical domain sits at the intersection of mobile telematics, usage-based insurance data capture, and driver behaviour analytics.
For insurtech platforms, UBI providers, and fleet telematics companies, this patent family represents a meaningful claim landscape. The breadth of the portfolio — five granted patents with staggered filing dates — suggests Big Will has constructed layered protection around the core Drive-It monitoring concept. Earnix, as an insurtech pricing and analytics vendor, would be a commercially rational enforcement target if its products ingest or process WCD-derived driver behaviour data. Any company in the telematics-to-insurance pipeline should assess exposure against these claims.
Should your telematics or UBI product run an FTO against the Drive-It patent family?
If your product captures, transmits, or analyses driver behaviour data using wireless devices — whether for usage-based insurance pricing, fleet scoring, or driver safety applications — the Drive-It patent family warrants an FTO review. The five patents span a decade of prosecution, meaning claim scope varies across the family. A single clearance opinion on one patent is insufficient; all five granted patents and any pending continuations must be mapped against your feature set.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the Drive-It claim landscape across all five patents simultaneously, flagging overlapping claim language and identifying prosecution history estoppel that may limit scope. Eureka’s claim monitoring alerts you if Big Will files further continuations from these application numbers — critical intelligence for any telematics or insurtech product team building in this space.

What this case signals for the driver monitoring and insurtech IP landscape
A five-patent assertion resolved in 35 days raises questions about enforcement strategy, patent quality, and the value of the Drive-It portfolio against insurtech targets.
E.D. Texas remains a plaintiff-favoured venue even for short-lived cases
Big Will chose the Eastern District of Texas — historically plaintiff-friendly in patent matters — despite Earnix having no obvious Texas nexus in the public record. The rapid dismissal means venue was never contested, but the filing choice is consistent with a leverage-driven strategy where the court’s reputation alone exerts pressure.
Five-patent assertions against a single defendant signal portfolio breadth claims
Asserting five related patents simultaneously raises the cost and complexity of any invalidity or non-infringement defence. For insurtech and telematics companies, this case is a reminder that drive-monitoring patent portfolios — even from smaller NPEs — can be asserted in clusters. Monitoring continuation applications from these five patents is advisable.
Big v Earnix — key questions answered
Big Will Enterprises filed a Notice of Dismissal with Prejudice under FRCP 41(a)(1)(A)(i) on February 29, 2024. The public record does not disclose the reason. The 35-day timeline — before Earnix filed any response — is consistent with a private settlement, a licensing arrangement, or a plaintiff decision that the claims were not viable to pursue.
Big Will asserted five patents: US9049558B2, US8452273B1, US10521846B2, US8737951B2, and US8559914B2. All relate to the Drive-It system, which uses wireless communication devices to monitor human activities while driving. Application filing dates span from approximately 2009 to 2015.
Dismissal with prejudice operates as a final judgment on the merits. Big Will Enterprises permanently loses the right to bring the same patent infringement claims against Earnix on these five patents in any federal court. It cannot refile the case at a later date, distinguishing it from a without-prejudice dismissal which would permit refiling.
The court ordered each party to bear its own attorneys’ fees and costs. No fee-shifting was ordered under 35 U.S.C. § 285, which requires a finding that the case was ‘exceptional.’ The absence of any such finding is consistent with the case terminating before any substantive merits briefing.
The Drive-It system is a platform that uses wireless communication devices (WCDs) to monitor human activities while driving. Big Will alleged Earnix infringed patents covering automatic programs for monitoring driver behaviour via WCDs. Earnix is an insurtech company offering pricing and analytics solutions, making it a plausible target if its products process WCD-derived driver data for insurance or risk scoring purposes.
