In one sentence

In Gilk v. Fisher, Judge Tunheim granted the Gilks’ preliminary injunction and denied Defendants’ competing injunction request.

Who this affects

Daniel Gilk, Samuel Gilk, Fly Boatworks, LLC, Mark Fisher, Errol Galt, Mark Baker, and Axocon Polymers, LLC are subject to the preliminary injunction; the Gilks must identify materials obtained from the email account, and Defendants’ requested injunction was denied.

What happened

In Gilk v. Fisher, Daniel Gilk and Samuel Gilk claimed that Mark Fisher, Errol Galt, Mark Baker, and Axocon Polymers, LLC were using Fly Boatworks’ trade secrets and taking a business opportunity involving Martac. They asked the court to stop that conduct while the case continued.

The court found that the Gilks showed a fair chance of proving that Fly Boatworks’ designs and innovations were trade secrets and that the Martac opportunity belonged to Fly Boatworks. The court also found likely, serious harm that money alone could not fix. Defendants separately claimed that the Gilks improperly accessed Fisher’s email, but the court found they had not shown a fair chance of success or irreparable harm on those claims.

Judge John R. Tunheim granted the Gilks’ motion for a temporary restraining order and preliminary injunction, continued restrictions requiring the parties to act for Fly Boatworks’ benefit, and did not require a bond. He denied Defendants’ motion and ordered the Gilks to identify documents and messages obtained from the email account within fourteen days.

Background

Daniel Gilk and Samuel Gilk sued individually and on behalf of Fly Boatworks, LLC. They alleged that Mark Fisher, Errol Galt, Mark Baker, and Axocon Polymers, LLC were disclosing Fly Boatworks’ trade secrets and taking Fly Boatworks’ business opportunities. Specifically, they alleged that the defendants were trying to replace Fly Boatworks with Axocon in a potentially lucrative skiff-boat project involving Martac Corp.

The Gilks also alleged that they developed important features of Fly Boatworks’ F2 Carbon skiff and components integrated into the M18 product. They claimed that these designs and innovations were trade secrets and that Fly Boatworks owned the opportunity to develop and market them. The Gilks sought a temporary restraining order and a preliminary injunction, which are emergency court orders intended to prevent harm while a case is pending.

Defendants filed their own motion for a temporary restraining order and preliminary injunction. They alleged that the Gilks and their lawyers improperly accessed Fisher’s email account and took confidential information, including communications protected by attorney-client privilege. Defendants sought orders stopping further access and use of the email materials and requiring the Gilks to identify and delete materials already obtained.

Plaintiffs’ Motion

The court applied the four factors used for temporary restraining orders and preliminary injunctions: likelihood of success on the merits, likely irreparable harm without an injunction, the balance of harms, and the public interest.

The court found that the Gilks showed a likelihood of success on two central issues. First, the court concluded at this stage that the F2 Carbon and M18 designs and innovations were likely trade secrets because they were not generally known or readily ascertainable, had value from their secrecy, and were likely protected through reasonable confidentiality efforts. The court noted that absolute secrecy was not required and that sharing information for business negotiations did not automatically destroy trade-secret protection.

Second, the court found that the Martac opportunity likely still belonged to Fly Boatworks. The defendants had not provided evidence that the Gilks had given up the opportunity, and the defendants’ alleged conduct suggested that they were attempting to pursue the opportunity through Axocon rather than through Fly Boatworks.

The court also found likely irreparable harm. It reasoned that losing the opportunity could damage Fly Boatworks’ goodwill, reputation, ability to be first to market with the innovations, and continued existence. The court found that money damages alone might not adequately repair those injuries. The balance of harms and public-interest factors also favored an injunction.

The court therefore entered a preliminary injunction aligned with the temporary restraining order. The order prohibits the parties from misappropriating or using Fly Boatworks’ trade secrets, designs, innovations, and inventions except for Fly Boatworks’ benefit and under its Operating Agreement. It also prohibits the parties from pursuing Fly Boatworks’ contracts or business opportunities for themselves, delivering Fly Boatworks’ prototypes or sending its designs to others without the required consent, and taking actions involving Fly Boatworks’ business or trade secrets except for Fly Boatworks’ sole benefit. Payments under Member Loan #4 were stayed. The court did not require a bond.

Defendants’ Motion

The court denied Defendants’ motion for a temporary restraining order and preliminary injunction. The court found that Defendants had not shown a likelihood of success because the evidence did not establish that the Gilks’ access to the email account was unauthorized. Although Fisher had created the account before becoming a Fly Boatworks owner and used it for personal matters, the account name suggested a company account, website inquiries were forwarded to it, and Fisher had shared account information with the Gilks.

The court also found no sufficient threat of irreparable harm. Fisher had changed the password, eliminating the apparent ongoing access concern, and past injury alone was insufficient. The court declined to categorically exclude the email evidence but ordered the Gilks to identify all documents and messages obtained from the account within fourteen days. Defendants could later challenge those materials’ admissibility and privilege status, and the Gilks could not rely on materials ruled inadmissible.

Disposition

The court granted Plaintiffs’ Motion for Temporary Restraining Order and Preliminary Injunction. It denied Defendants’ Motion for Temporary Restraining Order and Preliminary Injunction. It ordered the Gilks to identify all documents and messages obtained from the flyboatworksjet@gmail.com email address within fourteen days and entered judgment accordingly.
