UI Technologies v. Ricoma: Four-Patent Printer Infringement Action Stayed After 32 Days
UI Technologies, Inc. and UI Digital, Inc. filed a four-patent infringement action against Ricoma International Corp. and three individual defendants in Florida Southern District Court on 30 December 2022. The case was stayed and administratively closed after just 32 days, following a joint notice regarding mediation filed by the parties.
Four-patent toner printer dispute paused for mediation after 32 days
On 30 December 2022, UI Technologies, Inc. and UI Digital, Inc. (jointly, the plaintiffs) filed a patent infringement action in the U.S. District Court for the Southern District of Florida against Ricoma International Corp., Guofeng Frank Ma, Wenrui Henry Ma, and Miguel Andoni Ciarreta. The complaint asserted four patents — US10216117B2, US11442402B2, US11526122B2, and US10324395B2 — covering methods and systems for converting toner cartridge printers and toner cartridge printer under-printing technology.
The recorded Basis of Termination is 'Case Stayed.' The docket order — a paperless order entered by Judge Darrin P. Gayles — states that the action was stayed and closed for administrative purposes in light of the parties' Joint Notice Regarding Mediation, while permitting previously scheduled discovery to continue. A telephonic status conference was set for 1 March 2023.

US10216117B2 and three further patents — toner cartridge printer conversion and under-printing
Any company designing, manufacturing, distributing, or integrating toner cartridge printer conversion systems or under-printing workflows should treat these four patents as an active FTO concern. The plaintiffs' willingness to name individual executives alongside the corporate defendant suggests a high-commitment enforcement posture. R&D teams developing printer conversion kits, under-printing modules, or related consumable systems are the primary audience.
Official order — verbatim text
The court's paperless order stayed the action and closed it for administrative purposes solely in light of the parties' Joint Notice Regarding Mediation, without making any merits determination. Importantly, the order preserved ongoing discovery obligations, indicating the stay is procedural rather than dispositive at this stage.

R&D signals in the toner cartridge printer conversion space
Forward-looking patent and innovation intelligence derived from UI Technologies' and Ricoma's activity in the toner printer conversion and under-printing technology domain.
UI Technologies' multi-family printer conversion patent activity
With four granted patents spanning two distinct application families, UI Technologies appears to be building layered coverage over toner cartridge printer conversion and under-printing. Monitoring new continuations or divisionals from application families US15/993551 and US17/331412 can provide early warning of expanded claim scope in this domain.
Portfolio expansion riskFiling trends in toner printer conversion and under-printing systems
The toner cartridge printer conversion space — particularly under-printing methodology — is an area of active patent filing by multiple players. Tracking CPC subclass B41J and G03G classifications can surface emerging competitors and identify where claim density is highest, informing both FTO planning and R&D prioritisation for teams in the specialty printing sector.
Emerging filing activityRicoma's patent position in the printing and embroidery equipment space
Ricoma International Corp. operates across embroidery machinery and printing equipment. Assessing Ricoma's own patent filings — if any — in the printer conversion or under-printing domain reveals whether the company has developed proprietary designs that could support a freedom-to-operate defence or counter-assertion strategy in any future proceedings.
Competitor IP mappingAdjacent innovation opportunities near the asserted under-printing claims
The asserted patents focus on conversion methods and under-printing systems for toner cartridge printers. Adjacent white-space areas — such as inkjet-based under-printing conversion, substrate-agnostic under-print calibration, or cloud-connected conversion control systems — may represent lower-risk R&D pathways that sit outside the current claim landscape of the UI Technologies portfolio.

What this case signals for the toner printing IP landscape
A rapid stay after a joint mediation notice in a four-patent infringement action suggests the parties may be exploring resolution outside of full litigation.
Individual defendants named alongside the corporate entity — a deliberate enforcement posture
Naming three individuals — including persons with names consistent with leadership roles — alongside Ricoma International Corp. is a litigation tactic that raises the personal stakes of the dispute. This approach is sometimes used to apply pressure toward early resolution, and is notable in a case that reached a mediation notice within 32 days of filing.
Four-patent assertion signals a broad claim of portfolio coverage over printer conversion technology
Asserting four patents simultaneously across both conversion methods and under-printing systems suggests the plaintiffs believe their portfolio covers multiple angles of Ricoma's product line. Companies operating in toner cartridge printer conversion or under-printing should audit their designs against all four asserted patents, not just the primary claim.
UI v Ricoma — key questions answered
UI Technologies, Inc. and UI Digital, Inc. asserted four patents: US10216117B2, US11442402B2, US11526122B2, and US10324395B2. All four relate to toner cartridge printer conversion methods and under-printing systems. The case was filed in the Southern District of Florida on 30 December 2022.
Judge Darrin P. Gayles entered a paperless order staying the action and closing it for administrative purposes in light of a Joint Notice Regarding Mediation filed by the parties. The stay did not constitute a merits ruling. Previously scheduled discovery was permitted to continue, and a telephonic status conference was set for 1 March 2023.
Three individuals were named as defendants alongside Ricoma International Corp.: Guofeng Frank Ma, Wenrui Henry Ma, and Miguel Andoni Ciarreta. The specific basis for naming the individual defendants is not detailed in the available public record beyond their inclusion in the complaint.
The products at issue are described in the case record as a method and system for converting a toner cartridge printer, and toner cartridge printer devices, systems, and methods for under printing. The four asserted patents cover both the conversion methodology and the under-printing system architecture.
An administrative closure in this context is a procedural step, not a final disposition. The case was stayed pending mediation, meaning it remained live but inactive on the docket. The court retained jurisdiction and scheduled a status conference. The specific terms of any mediation or subsequent resolution are not disclosed in the available public record.
