ImageSails v. North Sails Group: Sail Printing Patent Dismissed With Prejudice
ImageSails, LLC brought an infringement action against North Sails Group LLC in the Northern District of California, asserting US10618618B2 covering sail printing processes. After 605 days of litigation, the plaintiff voluntarily dismissed the action with prejudice — permanently ending its ability to re-assert these claims against this defendant.
A sail printing patent suit ends permanently in N.D. California
ImageSails, LLC filed case 5:24-cv-07155 in the Northern District of California on 15 October 2024, asserting infringement of US10618618B2 — a patent directed to sail printing processes — against North Sails Group LLC, a prominent competitor in the performance sail manufacturing sector. The single patent in suit, application number US16/267076, covers fabrication methodology applied to sailing equipment.
The case closed on 12 June 2026 with the plaintiff dismissing the action with prejudice. The recorded basis of termination is 'Dismissed with Prejudice'; the docket order states that 'Plaintiff, ImageSails, LLC, dismisses this action with prejudice.' A dismissal with prejudice is a final adjudication on the merits as a matter of procedural law, extinguishing ImageSails' right to bring the same infringement claims against North Sails Group again. The specific terms driving this resolution are not disclosed in the available record.
The case ran for 605 days before reaching this endpoint — a duration consistent with early-to-mid stage district court proceedings in N.D. California. What prompted ImageSails to dismiss with prejudice rather than pursue trial or settle on disclosed terms is not apparent from the public record. Whether any agreement between the parties underlies the dismissal is unknown from available filings.

US10618618B2 — Sail Printing Process Patent
Any company involved in sail manufacturing, large-format marine printing, or composite sail panel fabrication should consider whether its production processes fall within the claims of US10618618B2. The patent is process-oriented, meaning that even firms not selling finished sails — such as print technology suppliers or materials processors — could potentially be within scope if their methods map to the claimed steps. This case confirms the patent is actively enforced.
Official order — verbatim text
The docket records ImageSails' own dismissal of the action with prejudice. This plaintiff-initiated exit carries significant procedural weight: it operates as a final merits-equivalent bar, preventing re-assertion of the same claims against North Sails Group. The public record does not disclose what considerations — substantive, commercial, or otherwise — drove the plaintiff to this irrevocable outcome.
Dismissed with prejudice: what the resolution means for both parties
Dismissal with prejudice bars all future re-filing of these claims
A dismissal with prejudice operates as a final judgment on the merits under federal procedural law. ImageSails cannot re-assert the same infringement claims under US10618618B2 against North Sails Group in any subsequent action. The claims are permanently extinguished in this dispute. The specific circumstances and any underlying terms that led the plaintiff to accept this outcome are not disclosed in the available record.
Permanent bar on re-filingImageSails loses its enforcement window against North Sails
By dismissing with prejudice, ImageSails surrenders its ability to pursue damages or an injunction against North Sails Group for the conduct alleged in this action. The patent US10618618B2 itself remains in force against third parties — this outcome affects only the claims as against this defendant. Whether any commercial arrangement underlies the dismissal is not disclosed in the available record.
Claims against defendant extinguishedNorth Sails Group obtains finality without a merits ruling
North Sails Group achieves a permanent end to this specific litigation without any court ruling on infringement, validity, or damages. The dismissal with prejudice provides strong preclusion protection: ImageSails cannot bring the same claims again. North Sails' underlying sail printing operations are no longer subject to this action, though the patent remains enforceable against others in the industry.
Full preclusion; no merits adjudicationUS10618618B2 remains a live enforcement risk for other sail makers
The dismissal with prejudice resolves only this bilateral dispute. US10618618B2 continues in force and ImageSails retains the right to assert it against other sail manufacturers or printing-process competitors. Businesses operating in the sail fabrication and digital printing sector should assess whether their processes fall within the patent's claims, as this outcome does not limit future enforcement beyond North Sails Group.

ImageSails v North — key questions answered
The case was dismissed with prejudice. ImageSails, LLC filed the dismissal, ending its infringement action against North Sails Group LLC permanently. The dismissal with prejudice means ImageSails cannot re-assert the same claims under US10618618B2 against North Sails Group in any future action. The specific terms or circumstances driving the dismissal are not disclosed in the available public record.
ImageSails asserted US10618618B2, filed under application number US16/267076, in the Northern District of California. The patent is directed to sail printing processes — a technology covering fabrication methods used in the production of sailing equipment. This was the sole patent in suit in case 5:24-cv-07155.
A dismissal with prejudice operates as a final merits-equivalent bar on re-filing. ImageSails permanently loses the right to bring the same infringement claims against North Sails Group under US10618618B2. However, the patent itself remains in force: ImageSails retains the ability to assert it against other parties in the sail printing and marine fabrication industry.
The case ran for 605 days, from filing on 15 October 2024 to closure on 12 June 2026, in the Northern District of California. This duration is consistent with cases reaching early-to-mid stage proceedings, though the specific litigation milestones reached before the dismissal are not detailed in the available public record.
No. The dismissal with prejudice resolves only the dispute between ImageSails and North Sails Group LLC. US10618618B2 remains a valid, enforceable patent. Other sail manufacturers, printing technology suppliers, and marine fabrication companies whose processes may overlap with the patent's claims remain subject to potential enforcement action by ImageSails.
