David’s Dozer V-loc System v. Deere & Co. — Case Transferred to Northern District of Iowa
David’s Dozer V-loc System, Inc. and inventor David Armas filed a patent infringement action in Florida’s Southern District against Deere & Co. and four co-defendants, asserting US10533300B1 over John Deere’s SmartGrade dozer blade technology. After 153 days, the court granted Deere’s motion and transferred the entire case to the Northern District of Iowa, closing the Florida proceedings.
SmartGrade dozer blade patent heads to Iowa after Florida transfer ruling
On December 29, 2023, David’s Dozer V-loc System, Inc. and its founder David Armas filed suit in the U.S. District Court for the Southern District of Florida (Case No. 1:23-cv-24931), asserting infringement of US10533300B1 against Deere & Co., John Deere Construction & Forestry Company, and three Florida-based equipment dealers — Dobbs Equipment, LLC, Everglades Equipment Corporation, and EFE, Inc. The accused products are the John Deere 333G SmartGrade Compact Track Loader and the SmartGrade SG96 six-way dozer blade attachment, which together implement the grade-control positioning functionality the patent allegedly covers.
The case closed in Florida on May 30, 2024 — just 153 days after filing — when the court granted in part Deere’s Motion to Sever and Transfer. The order directed the Clerk to transfer the entire action to the United States District Court for the Northern District of Iowa, which is the judicial home district for Deere & Co.’s principal operations. Rather than severing the dealer defendants and staying those claims in Florida, the court elected to consolidate all defendants in Iowa, suggesting the court found that the Northern District of Iowa was the more appropriate and efficient forum for the dispute as a whole.
A resolution in 153 days is consistent with a venue-focused motion practice rather than substantive merits engagement — no claim construction, invalidity briefing, or damages discovery appears to have concluded in Florida. What drove the transfer is not fully disclosed in the public record, but Deere’s Iowa domicile and likely witnesses, documents, and design records located there are factors courts routinely weigh under 28 U.S.C. § 1404(a). The case now proceeds in Iowa, where the litigation clock effectively restarts and the merits of the US10533300B1 infringement claims remain entirely unresolved.

Case transferred to Iowa: what the venue change means for both parties
Transfer under § 1404(a) moves the case, not the merits
A § 1404(a) transfer closes the originating docket and reopens the case in the transferee court. No substantive ruling on infringement, validity, or damages was issued in Florida. The Northern District of Iowa inherits the case in its entirety — including all defendants — and proceedings restart from the pleadings stage. This is a procedural venue resolution, not a win or loss on the patent claims.
Venue transfer — no merits rulingPlaintiffs must now litigate on Deere’s home turf in Iowa
David’s Dozer V-loc System and David Armas face increased logistical and cost burdens pursuing the case in the Northern District of Iowa rather than their home forum. Local Iowa counsel will likely be required, and travel costs rise for a small patent assertion entity. However, the infringement claims remain fully alive — the transfer does not prejudice the merits, and the plaintiffs retain the right to pursue all relief originally sought.
Claims survive — forum shiftsDeere secures home-court advantage in Iowa
Deere & Co. successfully argued that the Northern District of Iowa is the more convenient and appropriate forum — likely citing the location of its design teams, engineering records, and key witnesses in the Midwest. Litigating near its principal operations typically reduces Deere’s per-case costs and allows access to familiar local counsel. The dealer co-defendants (Dobbs, Everglades, EFE) were also transferred rather than severed, consolidating all defence in Iowa.
Favourable forum securedSmartGrade product line faces unresolved IP exposure going forward
Until the Northern District of Iowa rules on the merits of US10533300B1, the John Deere 333G SmartGrade and SG96 dozer blade attachment carry unresolved infringement exposure. Competitors and supply-chain partners in the grade-control and compact track loader segment should monitor the Iowa docket. A finding of infringement or validity in Iowa would have direct implications for the broader SmartGrade product ecosystem and potentially the wider precision grading market.

Official order — verbatim text
The transfer order granted Deere’s motion in part, declining to sever and stay the dealer defendants in Florida and instead consolidating all parties in Iowa. This suggests the court found a single consolidated Iowa forum more efficient than bifurcated proceedings across two districts. Critically, the order makes no substantive finding on infringement or validity of US10533300B1 — the Florida court’s role was purely procedural. Both parties enter Iowa proceedings with their legal positions entirely intact.
US10533300B1 — V-loc dozer blade positioning system for compact track loaders
US10533300B1, filed under application number US16/055094, protects a V-loc system for positioning and controlling a dozer blade attachment on compact track loaders. The patent covers the mechanical and control-system geometry enabling precise blade placement — the core functionality Deere implements in its SmartGrade product line. The B1 designation indicates the patent issued without pre-grant publication, meaning it emerged directly from examination with no intervening published application. The patent is held by David Armas, the named inventor and co-plaintiff, through David’s Dozer V-loc System, Inc.
The strategic significance of US10533300B1 lies in its potential read on the SmartGrade-enabled 333G Compact Track Loader and SG96 six-way blade — Deere products targeted at precision earthmoving and site-prep markets where grade-control technology commands a premium. If the claims are construed broadly enough to cover Deere’s implementation, the exposure could extend beyond the 333G to other SmartGrade-compatible machines. Competitors in the compact track loader and dozer attachment segment — including Caterpillar, Bobcat, and Case — should assess whether their own blade-control implementations intersect with this patent’s claim landscape.
Should you run an FTO analysis against US10533300B1?
Any company developing, manufacturing, or distributing compact track loaders with integrated blade-positioning or grade-control systems should evaluate US10533300B1 as part of a freedom-to-operate review. The patent’s assertion against Deere’s flagship SmartGrade system — one of the most commercially prominent products in the precision earthmoving segment — signals that the patent holder views the claims as broadly applicable. Equipment dealers and OEM integrators supplying blade control attachments face analogous risk, as the inclusion of dealer defendants in this case demonstrates.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map US10533300B1 claim elements against product specifications and competing prior art in minutes. You can identify where your blade-positioning architecture diverges from the patent’s independent claims, surface prior art that may support an invalidity argument, and benchmark the patent’s family scope across jurisdictions — all before committing to Iowa litigation monitoring or redesign investment.

What this case signals for the construction equipment IP landscape
A transfer to Iowa repositions — but does not resolve — a meaningful patent challenge to Deere’s SmartGrade grade-control product line.
Venue strategy is a first-line defence for large OEMs against NPE suits
Deere’s rapid move to transfer within 153 days is consistent with a playbook large OEMs use to shift smaller plaintiffs away from plaintiff-friendly or inconvenient forums. Filing against a company’s home-district affiliates does not guarantee a plaintiff retains that forum — Deere’s success here underscores the importance of venue analysis before filing.
Grade-control patents face growing enforcement risk as smart machinery adoption accelerates
The assertion of US10533300B1 against Deere’s SmartGrade system signals that inventor-held patents in the dozer blade and grade-control space are being actively enforced. R&D teams developing precision earth-moving or blade-positioning systems should treat this patent family as a live FTO concern, regardless of the Iowa venue outcome.
David’s v Deere — key questions answered
The Southern District of Florida transferred the entire case to the Northern District of Iowa on May 30, 2024, 153 days after filing. The court granted Deere’s motion to transfer, declined to sever the dealer defendants, and closed the Florida docket. No merits ruling on infringement or validity of US10533300B1 was issued.
US10533300B1, filed under application US16/055094, is the sole patent asserted. It covers a V-loc dozer blade positioning system. The accused products are the John Deere 333G SmartGrade Compact Track Loader and the SmartGrade SG96 six-way dozer blade attachment.
The court granted Deere’s motion to transfer under 28 U.S.C. § 1404(a), consistent with factors including Deere’s principal operations, key witnesses, and engineering records being located in Iowa. The public order does not detail the full reasoning, but the consolidation of all defendants in Iowa rather than a sever-and-stay suggests the court prioritised efficiency in a single forum.
No. A § 1404(a) transfer is purely procedural. The infringement claims under US10533300B1 survive intact and will be adjudicated in the Northern District of Iowa. The Florida court made no finding on validity, infringement, or damages.
The defendants are Deere & Co., John Deere Construction & Forestry Company, Dobbs Equipment LLC, Everglades Equipment Corporation, and EFE Inc. The latter three are Florida-based equipment dealers. All defendants were transferred to Iowa rather than having the dealer claims severed and stayed in Florida.
