Sea Swivel v. Rhodan Marine: Trolling Motor Patent Case Frozen by PTAB Stay
Sea Swivel Inc. sued Rhodan Marine Systems of Florida over US12258111B1, a patent covering swiveling trolling motor mounts. Judge Roy K. Altman stayed the entire district court action within 77 days of filing, pending a PTAB ruling on Rhodan’s validity petition — effectively pausing all injunctive and merits proceedings.
Trolling Motor Patent Dispute Frozen Pending PTAB Challenge
Sea Swivel Inc. filed suit against Rhodan Marine Systems of Florida, LLC on August 8, 2025 in the Southern District of Florida (Case No. 1:25-cv-23581), asserting infringement of US12258111B1, a patent directed at swiveling trolling motor mounts. The case was assigned to Judge Roy K. Altman and represented an attempt by Sea Swivel to protect what appears to be a core product differentiator in the competitive marine electronics and propulsion accessories market.
Within 77 days of filing, on October 24, 2025, Judge Altman granted Rhodan Marine’s Motion to Stay, administratively closing the case until the Patent Trial and Appeal Board rules on Rhodan’s petition — presumably an inter partes review (IPR) challenging the validity of US12258111B1. All pending motions, including Sea Swivel’s Motion for Preliminary Injunction, were denied as moot but may be re-raised once the stay is lifted.
The speed of the stay grant — before any preliminary injunction hearing — is notable and consistent with courts deferring to PTAB proceedings where validity is genuinely disputed. The public record does not reveal the specific grounds of Rhodan’s PTAB petition or the likelihood of institution, leaving the ultimate commercial outcome uncertain. A joint status report is due within seven days of the PTAB decision or March 25, 2026, whichever comes first.
Filing to Case Stayed in 77 days
77 days from filing to administrative closure — resolved procedurally before any merits ruling
Case stayed pending PTAB: what the administrative closure means for both parties
A stay is not a dismissal — the case is paused, not ended
An administrative closure pending PTAB review means the district court retains jurisdiction but suspends all proceedings until the PTAB rules on patent validity. If the PTAB institutes review and invalidates claims, Sea Swivel’s infringement case could collapse. If the PTAB denies institution or confirms validity, the district court action resumes — potentially with strengthened patent claims and renewed injunction motions.
PTAB IPR staySea Swivel’s injunction bid is on hold — momentum lost
Sea Swivel’s Motion for Preliminary Injunction was denied as moot, meaning Rhodan Marine can likely continue selling its products during the PTAB review period. For a smaller IP holder, this delay can be commercially significant. However, Sea Swivel retains the right to re-raise all motions once the stay lifts, preserving its legal options if the patent survives PTAB scrutiny.
Injunction pausedRhodan Marine buys time via the PTAB route
Securing a stay before any merits ruling is a strategic win for Rhodan Marine. By successfully petitioning the PTAB and obtaining a district court stay, Rhodan avoids immediate injunctive relief and shifts the battleground to inter partes review — a forum widely considered more favourable to patent challengers. The outcome now hinges on whether the PTAB institutes review and on what grounds.
IPR strategy succeededMarine accessory IP holders face a viable IPR deflection route
This case signals that defendants in niche marine hardware patent disputes can effectively delay district court enforcement by filing PTAB petitions. Companies operating in the trolling motor mount and marine propulsion accessories space should monitor the PTAB docket for proceedings against US12258111B1. A PTAB institution decision could reshape freedom-to-operate assessments across the sector.

Official order — verbatim text
The court’s order granting a stay and administratively closing the case reflects a deliberate judicial preference for PTAB proceedings to resolve validity questions before district court merits are litigated. The denial of the preliminary injunction as moot is procedurally significant: it does not constitute a ruling on the merits of Sea Swivel’s infringement or irreparable harm arguments. Both parties’ substantive positions remain entirely unresolved, and the case’s trajectory depends entirely on whether the PTAB institutes inter partes review of US12258111B1.
US12258111B1 — Swiveling Trolling Motor Mount Technology
US12258111B1 covers swiveling trolling motor mount technology — a mechanical interface system that allows trolling motors to pivot or rotate relative to a boat’s transom or bow mount structure. The application number US18/897527 suggests a relatively recent filing. Trolling motor mounts are critical components in the recreational and professional fishing boat market, where precise motor positioning directly affects boat control, fuel efficiency, and angling performance.
For Sea Swivel, this patent appears to represent a core product differentiator in a competitive niche where mechanical design innovations can command meaningful market premiums. If the patent’s claims survive PTAB review, it could give Sea Swivel a durable enforcement position against Rhodan Marine and potentially other manufacturers of swivel-style motor mounting systems. Competitors in the marine accessories space should monitor the PTAB docket closely, as any claim narrowing during IPR will directly affect the scope of enforceable IP in this product category.
Should you run an FTO analysis against US12258111B1?
Any manufacturer, OEM supplier, or product designer working on trolling motor mounting systems — including swivel, pivot, or rotating transom-mount assemblies — should consider a freedom-to-operate analysis against US12258111B1. The pendency of PTAB review does not eliminate infringement risk; if the PTAB denies institution or confirms claims, the patent remains fully enforceable and district court litigation resumes.
PatSnap Eureka’s FTO Search Agent can map the claim language of US12258111B1 against your product specifications, identify prior art already cited in the PTAB proceeding, and flag design-around opportunities before the case returns to district court. With a potential enforcement resumption by mid-2026, now is the right time to build a defensible FTO position for your marine hardware product line.

What this case signals for the marine accessories IP landscape
A rapid stay in a niche hardware patent dispute illustrates how PTAB petitions reshape enforcement timelines across the marine equipment sector.
File PTAB petitions early to neutralise preliminary injunction risk
Rhodan Marine’s strategy demonstrates that a timely PTAB petition can eliminate the threat of a preliminary injunction before it is heard. Defendants in product-adjacent patent disputes should assess IPR viability immediately upon being served — the stay mechanism rewards those who move quickly.
Sea Swivel’s enforcement window is effectively delayed by up to one year
With the stay in place through at least March 2026, Sea Swivel cannot obtain injunctive relief during PTAB review. Patent holders in competitive product categories should weigh whether district court litigation alone provides sufficient speed — or whether parallel PTAB monitoring and licensing strategies are warranted.
SEA v RHODAN — key questions answered
The stay administratively closes the district court case until the PTAB rules on Rhodan Marine’s validity petition against US12258111B1. No infringement merits have been decided. Sea Swivel retains the right to re-raise all motions, including its preliminary injunction request, once the stay is lifted.
The patent at issue is US12258111B1 (application no. US18/897527), which covers swiveling trolling motor mount technology — mechanical systems that allow trolling motors to rotate or pivot on marine vessels. Sea Swivel asserts Rhodan Marine’s products infringe this patent.
Sea Swivel’s Motion for Preliminary Injunction (ECF No. 30) was denied as moot following the court’s grant of Rhodan Marine’s Motion to Stay. The denial was procedural — not a ruling on the merits of irreparable harm or likelihood of success. Sea Swivel may re-raise the motion once the stay is lifted.
The court’s October 24, 2025 order requires the parties to file a joint status report within seven days of the PTAB’s decision or March 25, 2026 — whichever is sooner. This suggests the PTAB institution decision is expected by approximately March 2026.
