Zito LLC v. ABG Systems North America: Inventory Management Patent Suit Dismissed
Zito LLC filed suit in the Eastern District of Texas asserting three patents covering smart vending and automated inventory management against ABG Systems’ MATRIX and White C product lines. The case closed after 224 days when Zito voluntarily dismissed without prejudice before ABG Systems filed any responsive pleading, leaving the door open for future enforcement.
Pre-Answer Dismissal in Smart Vending Patent Row Leaves Dispute Unresolved
On 31 March 2025, Zito LLC filed a patent infringement complaint in the United States District Court for the Eastern District of Texas (Case No. 4:25-cv-00323) before Judge Sean D. Jordan. The suit asserted three patents — US10867461B2, US11127239B2, and US11710364B2 — against ABG Systems North America, Inc., targeting the defendant’s MATRIX Inventory Management product line (including View DLS 13D, View DLS 8D, View ECO Locker, View Helix, View Max, View Mini, View DLS-V, View Toolport, and View WIZ) as well as the ABG Advanced Inventory Management Vending Solutions product known as the White C.
The case closed on 10 November 2025 when Zito invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i) to voluntarily dismiss the action. Critically, the dismissal was recorded as without prejudice, and the public docket confirms that ABG Systems had not served an answer or motion for summary judgment before dismissal was filed. Each party was ordered to bear its own costs and fees, with no damages or injunctive relief awarded.
A voluntary dismissal taken before any responsive pleading is relatively swift by E.D. Texas standards and may suggest the parties reached a private accommodation, Zito elected to recalibrate its enforcement strategy, or pre-suit negotiations shifted the commercial calculus. Because no merits ruling was issued, the validity and infringement of all three patents remain legally undetermined. The without-prejudice designation means Zito retains the right to reassert these patents against ABG Systems or third parties in future proceedings.
Filing to Voluntary dismissal in 224 days
224 days — case closed before defendant filed any answer or dispositive motion
Voluntarily dismissed: what the without-prejudice ruling means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to exit
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss a case without court approval provided the defendant has not yet served an answer or motion for summary judgment. ABG Systems had not done so here. The dismissal is self-executing — it takes effect upon filing and requires no judicial order. No merits ruling exists, and no estoppel attaches to Zito’s infringement or validity positions.
No merits adjudicationWithout prejudice confirmed — but the distinction matters
A without-prejudice dismissal leaves the plaintiff free to refile the same claims in the same or another court, subject to any applicable statute of limitations. A with-prejudice dismissal, by contrast, operates as a final judgment on the merits, permanently barring re-litigation. The docket here expressly states ‘without prejudice,’ meaning Zito retains full re-filing rights. The public record does not disclose whether any private settlement or licensing agreement accompanied the dismissal.
Refiling rights preservedABG Systems exits with no admission — but faces residual risk
Because no answer was filed and no merits ruling issued, ABG Systems makes no admission of infringement and receives no declaratory judgment of non-infringement or invalidity. The without-prejudice nature of the dismissal means the threat of renewed litigation over the same three patents persists. ABG Systems should continue to monitor Zito’s enforcement activity and consider whether a freedom-to-operate analysis or proactive licensing discussion is warranted.
No declaratory judgment obtainedSmart vending IP cloud remains: enforcement could return
Competitors and customers in the automated vending and industrial inventory management sector should note that all three Zito patents survive this case legally intact, with no invalidity finding and no claim construction on record. Zito’s willingness to refile — or to assert these patents against other MATRIX-style or locker-based vending system vendors — is not diminished by this outcome. Industry participants deploying similar vending or tool-dispensing architectures should treat this as a live IP risk.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) — the self-executing pre-answer exit right — and expressly records the action as ‘without prejudice.’ The phrasing that ABG Systems ‘has not served an answer or motion for summary judgment’ is a required procedural recital confirming the plaintiff’s unilateral right to dismiss. No infringement finding, no invalidity ruling, and no claim construction issued. The costs-bearing provision is mutual and neutral, consistent with a clean procedural exit rather than a negotiated settlement with financial terms on the public record.
US10867461B2, US11127239B2 & US11710364B2 — Automated Vending & Inventory Management
The three asserted patents — US10867461B2 (application US15/200048), US11127239B2 (application US15/212644), and US11710364B2 (application US17/389896) — span application dates from approximately 2016 through 2021, suggesting a maturing portfolio built across successive invention cycles. The patents sit in the technical domain of automated vending, inventory dispensing, and locker-based asset management — a field increasingly relevant to industrial MRO supply, tooling control, and workplace consumables management.
For competitors deploying vending locker systems — particularly modular locker arrays, helical coil dispensers, or DLS-style drawer systems analogous to ABG Systems’ View product line — this portfolio represents a meaningful IP risk. The staggered application dates indicate Zito may hold continuation or continuation-in-part claims that follow product evolution in the sector. No court has yet construed the claims, meaning the effective scope remains broad until challenged, making proactive clearance and inter partes review evaluation strategically important for any market participant in this space.
Should you run an FTO against US10867461B2, US11127239B2, and US11710364B2?
Any company manufacturing, importing, or selling automated vending machines, inventory dispensing lockers, or IoT-connected tool-crib or MRO management systems should treat this patent family as a live freedom-to-operate concern. The product types targeted in this case — modular locker systems, helix dispensers, and DLS-format vending units — are widely used in manufacturing, healthcare supply, and facilities management. Zito’s without-prejudice exit means enforcement risk persists across the entire market, not just against ABG Systems.
PatSnap Eureka’s FTO Search Agent can rapidly map the claim scope of all three Zito patents against your specific product architecture, flag any overlap with the asserted independent claims, and surface prior art that could support an IPR petition if invalidation is the preferred defensive strategy. Because no Markman order exists in this case, Eureka’s AI-driven claim interpretation tools are especially valuable for establishing your own defensible claim-scope assessment before litigation risk escalates.

What this case signals for the automated vending and inventory IP landscape
A pre-answer voluntary dismissal in E.D. Texas rarely signals full resolution — it often marks a strategic pause or a pivot to private negotiation.
Without-prejudice dismissal keeps enforcement pressure alive on ABG Systems
Zito’s ability to refile against ABG Systems or assert the same three patents against other market participants is entirely unaffected. Companies deploying MATRIX-type vending locker architectures or automated tool-dispensing systems should treat this case as an active threat signal, not a resolved dispute.
E.D. Texas remains a favored venue for vending and industrial IoT patent assertions
The Eastern District of Texas continues to attract patent infringement filings in hardware-connected inventory and vending system technology. The pre-answer exit here does not diminish the jurisdiction’s relevance — future filings by Zito or similarly positioned NPEs are plausible in the same court before the same judge.
Zito v ABG — key questions answered
A without-prejudice dismissal under Rule 41(a)(1)(A)(i) means Zito LLC retains the full legal right to refile its infringement claims against ABG Systems North America or any other party. No merits ruling was issued, so the validity and infringement of US10867461B2, US11127239B2, and US11710364B2 remain legally undecided. ABG Systems received no declaratory judgment of non-infringement or invalidity.
The complaint targeted ABG Systems’ MATRIX Inventory Management line — including the View DLS 13D, View DLS 8D, View ECO Locker, View Helix, View Max, View Mini, View DLS-V, View Toolport, and View WIZ — as well as the ABG Advanced Inventory Management Vending Solutions product known as the White C. All three Zito patents were asserted across these product lines.
Zito LLC asserted three US patents: US10867461B2 (application US15/200048), US11127239B2 (application US15/212644), and US11710364B2 (application US17/389896). All three relate to automated vending and inventory management technology. The patents span application filings from approximately 2016 to 2021, suggesting a portfolio built across multiple invention cycles.
The public docket does not disclose the reason for the pre-answer voluntary dismissal. Possible explanations consistent with the known facts include private licensing or settlement discussions, a strategic decision to refile in a different venue or with an amended complaint, or a reassessment of litigation timing. Because ABG Systems had not yet answered, Zito could exit as a matter of right under FRCP 41(a)(1)(A)(i) without court approval.
Yes, this outcome has sector-wide relevance. Because the three Zito patents were not invalidated and no claim construction occurred, they remain fully enforceable against any party. Companies selling modular locker systems, helical vending dispensers, or IoT-connected inventory management hardware analogous to the accused ABG Systems products face the same IP risk. A proactive freedom-to-operate review against Zito’s patent family is advisable for any competitor in this market.
