STS Refill Technology v. Scribe Opco: DTF Printer Patent Suit Ends in Voluntary Dismissal

Case Overview

The Parties

The Patents at Issue

Two issued U.S. patents formed the basis of the infringement claims:

• • U.S. Patent No. 12,077,010 B2 (Application No. 17/215,478)
• • U.S. Patent No. 12,128,699 B2 (Application No. 17/938,852)

The Accused Products

The complaint targeted specific DTF printer models distributed by ColDesi, including:

• • Roland VersaSTUDIO BY-20
• • DTF-12HT
• • DTF-24HT
• • DTF-24H4

Legal Representation

The plaintiffs were represented by attorneys from McAndrews, Held & Malloy, Ltd., Shumaker, Loop & Kendrick, LLP, and Tucker Law PA — including attorneys Matthew G. McAndrews, Paul W. McAndrews, Matthew Sean Tucker, and John Todd Timmerman. Notably, Shumaker, Loop & Kendrick, LLP appeared on both sides of the caption, with John Todd Timmerman listed in connection with defendant Scribe Opco’s representation as well, suggesting possible transitional or multi-party counsel arrangements worth monitoring in the docket.

Litigation Timeline & Procedural History

The case was filed in the Southern District of Florida, a venue with an active patent litigation docket and established procedural practices for IP cases. The district’s relatively predictable scheduling and proximity to ColDesi’s operational presence may have influenced venue selection.

At just 78 days from filing to dismissal, the case closed before any substantive court activity was recorded. Scribe Opco neither filed an answer nor a motion for summary judgment — the precise procedural posture that makes a Rule 41(a)(1)(A)(i) voluntary dismissal available as of right, requiring no court order or defendant consent.

No claim construction proceedings, Markman hearings, motions to dismiss, or discovery disputes were reported within this compressed timeline.

The Verdict & Legal Analysis

Outcome

On April 18, 2025, the plaintiffs voluntarily dismissed this action without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). No damages were awarded. No injunctive relief was granted or denied. The case closed at the first instance level with no merits adjudication.

A dismissal without prejudice means the plaintiffs retain the right to refile the same claims in the future, provided applicable statutes of limitations and any other procedural constraints are satisfied.

Verdict Cause Analysis

Because the dismissal was entered before the defendant responded to the complaint, no substantive legal rulings were issued — no claim construction, no invalidity analysis, no infringement findings. The legal record reflects a unilateral plaintiff decision to exit the litigation at the earliest possible stage.

Several strategic rationales commonly underlie such early voluntary dismissals:

• Pre-answer settlement or licensing agreement: Parties may have reached a commercial resolution that eliminated the need for continued litigation, even without formal settlement documentation appearing in the public record.
• Reassessment of claim scope: Plaintiff counsel may have identified claim construction vulnerabilities following a deeper pre-trial analysis of the accused products against the patent claims.
• Venue or timing recalibration: Plaintiffs may intend to refile in a different district or await developments in related proceedings before re-asserting.
• Defendant’s informal response: Though Scribe Opco filed no formal answer, informal communications or a credible invalidity challenge may have influenced the decision.

None of these rationales can be confirmed from the available public record, and no inference of weakness on either side should be drawn from the dismissal alone.

Legal Significance

The Rule 41(a)(1)(A)(i) mechanism used here is a well-established procedural tool, but its use in patent litigation carries specific strategic weight. Importantly, a second voluntary dismissal of the same claims would operate as a dismissal with prejudice under Rule 41(a)(1)(B) — the so-called “two dismissal rule.” Plaintiffs and their counsel must account for this risk if refiling is contemplated.

For the DTF printing patent landscape, the dismissal leaves the validity and enforceability of U.S. Patent Nos. 12,077,010 B2 and 12,128,699 B2 fully intact and untested in litigation. Both patents remain active assets in STS Refill Technology’s portfolio with no adverse rulings on record.

Strategic Takeaways

• For Patent Holders: Early voluntary dismissal preserves optionality. Filing suit can prompt licensing discussions or reveal the defendant’s invalidity posture before committing to full litigation costs. However, the two-dismissal rule demands careful tracking across jurisdictions.
• For Accused Infringers: When a plaintiff dismisses before you answer, your invalidity and non-infringement arguments remain unlitigated. Documenting your design-around analysis and any informal communications becomes critical if the claims are later reasserted.
• For R&D Teams: The commercial specificity of the accused products — named DTF printer models — illustrates that freedom-to-operate (FTO) analysis must extend to distributed hardware, not just manufactured components. Distributors like ColDesi face co-plaintiff risk exposure in assertion strategies tied to their product lines.

Industry & Competitive Implications

The DTF printing market has grown substantially since 2020, driven by lower equipment costs and increasing demand for short-run, full-color textile decoration. The assertion of two recently issued patents — both with application dates suggesting prosecution activity between 2021 and 2022 — reflects active IP portfolio building in this space.

The involvement of ColDesi as a co-plaintiff is commercially significant. As a major distributor of DTF equipment in North America, ColDesi’s participation signals that patent assertion in this segment may be linked to distribution channel enforcement strategies, not merely manufacturing-level disputes.

For companies operating in the DTF printing ecosystem — whether as equipment manufacturers, consumable suppliers, or commercial decorators — this case is a signal that patent holders are actively monitoring competitor product lines. The breadth of accused products across multiple printer models suggests the asserted claims may be written at a system or process level rather than tied to narrow component designs.

Licensing activity in adjacent digital printing technologies (DTG, UV printing) has intensified over the past five years, and DTF may follow a similar trajectory as patent portfolios in this space mature.
