Pipp Mobile Storage Systems v. Innovative Growers Equipment — Dismissed With Prejudice
Pipp Mobile Storage Systems filed suit against Innovative Growers Equipment in April 2021, asserting infringement of US10806099B2, a patent covering an innovative airflow system. After nearly three years of litigation in the Northern District of Illinois, the case closed in January 2024 when the plaintiff itself moved to dismiss with prejudice — a notably self-imposed finality.
Plaintiff-initiated dismissal closes airflow patent dispute in Illinois
Pipp Mobile Storage Systems, Inc. filed Case No. 1:21-cv-02104 against Innovative Growers Equipment, Inc. in the Northern District of Illinois on 19 April 2021. The infringement action centred on US10806099B2, a patent directed to an innovative airflow system relevant to mobile storage and commercial growing environments. Judge Sara L. Ellis presided over the first-instance proceedings, with Thorelli & Associates representing the plaintiff and Saul Ewing LLP acting for the defendant.
The case closed on 10 January 2024 following a telephone conference at which the court granted Pipp’s own opposed motion to dismiss with prejudice. Critically, the defendant’s simultaneously pending motion for entry of final judgment was denied as moot, indicating the court resolved the case entirely on the plaintiff’s voluntary — but prejudicial — dismissal motion rather than on the merits. A dismissal with prejudice operates as a final adjudication on the merits, permanently barring Pipp from reasserting the same claims against Innovative Growers Equipment.
The ~1,000-day litigation timeline and the plaintiff’s decision to seek a prejudicial dismissal rather than proceed to judgment suggests the parties may have reached a private resolution, or that Pipp concluded further litigation was commercially unviable. The public record does not disclose any settlement terms, licensing arrangement, or damages payment. The fact that the defendant’s motion for final judgment was pending simultaneously adds an unusual dynamic: Pipp moved first, likely to control the terms of exit before an adverse judgment could be entered.

Stipulation of dismissal — official text
The court’s 10 January 2024 telephone conference order granted Pipp’s ‘opposed motion to dismiss with prejudice,’ simultaneously rendering the defendant’s pending final judgment motion moot. The phrase ‘opposed motion’ confirms that Innovative Growers Equipment contested the dismissal vehicle, likely preferring a merits judgment that might have carried stronger preclusive or cost-shifting effects. The court’s grant of Pipp’s motion is procedurally orthodox — plaintiffs generally retain the right to dismiss with prejudice — but the sequence reveals a contested endgame in which both parties were competing to control the form of the final order.
US10806099B2 — Innovative Airflow System for Mobile Storage Environments
US10806099B2 (application number US16/112077) protects an innovative airflow system developed by Pipp Mobile Storage Systems. The patent sits at the intersection of mobile racking infrastructure and environmental control — a technically distinct niche that has grown significantly as commercial cannabis cultivation and controlled-environment agriculture have scaled. Airflow management in dense, mobile shelving configurations presents genuine engineering complexity, and a patent in this space can confer meaningful exclusivity over equipment architecture used throughout commercial grow facilities.
For competitors in the mobile storage and commercial growing equipment sector, US10806099B2 represents a live enforcement risk. Pipp’s willingness to sustain nearly three years of litigation before settling or withdrawing signals genuine conviction in the patent’s commercial relevance. The patent’s claim scope — particularly around airflow integration with mobile racking systems — should be reviewed carefully by any equipment manufacturer or distributor whose products operate in controlled growing environments. Any continuation applications stemming from US16/112077 may extend or refine this claim landscape further.
Should your product team run an FTO against US10806099B2?
If your company designs, manufactures, or sells airflow systems integrated with mobile storage or racking equipment — particularly for commercial agriculture, cannabis cultivation, or controlled-environment facilities — US10806099B2 is a patent you should assess before launch or expansion. This litigation demonstrates that Pipp Mobile Storage Systems actively enforces its IP, and the patent remains fully valid and in force. Equipment distributors and OEM suppliers operating in the same vertical face the same exposure that brought Innovative Growers Equipment into three years of federal litigation.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the claims of US10806099B2, surface related continuation applications, and flag any design-around opportunities before you go to market. Claim monitoring through Eureka also alerts your team if Pipp files new continuations or divisionals that expand the protected scope — giving you early warning rather than a litigation notice.

What this case signals for the commercial growing equipment IP landscape
Plaintiff-controlled dismissals with prejudice after extended litigation carry specific enforcement and competitive intelligence signals worth tracking.
Dismissal with prejudice does not neutralise the patent as a competitive threat
US10806099B2 survived this litigation intact. Competitors in the mobile growing and airflow equipment sector should not read this dismissal as IP clearance. Pipp retains full rights to assert the same patent against other parties, and the case record may have generated claim-construction arguments useful in future proceedings.
Plaintiff-led exits after ~3 years suggest the merits picture was shifting
When a plaintiff moves to dismiss with prejudice after the defendant has already filed for final judgment, it typically suggests the plaintiff’s litigation position had weakened — whether through prior art discovery, claim construction developments, or cost-benefit recalibration. Monitoring the docket history for IPR filings or claim construction rulings would clarify this.
Pipp v Innovative — key questions answered
The case was dismissed with prejudice on 10 January 2024, on the plaintiff Pipp Mobile Storage Systems’ own motion. The dismissal was granted by Judge Sara L. Ellis following a telephone conference, and bars Pipp from refiling the same patent infringement claims against Innovative Growers Equipment.
Pipp asserted US10806099B2 (application number US16/112077), a patent covering an innovative airflow system. The patent is relevant to mobile storage racking systems used in commercial growing and controlled-environment agriculture.
A dismissal with prejudice operates as a final adjudication on the merits under US federal civil procedure. Pipp is permanently barred from filing a new lawsuit against Innovative Growers Equipment based on the same claims under US10806099B2. However, the patent itself remains valid and enforceable against other parties.
Innovative Growers Equipment had filed a motion for entry of final judgment (docket item 129) before Pipp moved to dismiss. Once the court granted Pipp’s dismissal with prejudice motion, the defendant’s judgment motion became procedurally unnecessary — the case was already terminated — so the court denied it as moot.
No. The dismissal resolves only the specific dispute between Pipp and Innovative Growers Equipment. US10806099B2 remains in force and Pipp retains the right to enforce it against other parties. Companies in the mobile storage or commercial growing airflow equipment sector should treat the patent as an active risk and consider a freedom-to-operate analysis.
