Takeaway

In short, a trade-secret injunction may reach future markets and continue long enough to erase an unfair head start, even after some related technology becomes public.

Background

Lamb-Weston developed a helical blade and water-feed system for making curlicue french fries. McCain, a competitor developing its own system, hired the contractor who made Lamb-Weston’s blades and allegedly received a copy of Lamb-Weston’s confidential patent application from an employee who later joined McCain. Although patents issued for the blade system, Lamb-Weston maintained that the blade’s specifications, materials, and manufacturing process remained secret.

Lamb-Weston sued for trade-secret misappropriation. A magistrate judge entered an eight-month preliminary injunction barring McCain from producing or selling products made with the disputed technology. McCain appealed, challenging both the finding that Lamb-Weston was likely to succeed and the injunction’s worldwide reach and duration.

Issues

Issue #1

Whether the evidence supported preliminary relief based on likely trade-secret misappropriation.

Holding

Yes. The finding that Lamb-Weston was likely to succeed was not clearly erroneous, and granting the injunction was not an abuse of discretion.

Reasoning

Under Oregon law, trade-secret misappropriation requires a valuable commercial design, a confidential relationship with the person who disclosed it, and key design features created by the party claiming protection. The appellate court reviewed the preliminary injunction for abuse of discretion, including whether its factual findings were clearly erroneous.

McCain knew the contractor was still making Lamb-Weston’s blades, yet asked him to make a helical blade without directing its specifications, materials, or fabrication. The court found it reasonable to infer that he would draw on what he had learned from Lamb-Weston, despite his assurance that confidentiality would not be a problem.

The contractor’s claim that he left both companies’ blades in the open did not defeat that inference. Lamb-Weston employees testified that they had not seen McCain’s blade at his shop, and Lamb-Weston sought a confidentiality agreement when it learned of his work for McCain. Unchallenged testimony that McCain had also received Lamb-Weston’s confidential patent application reinforced the finding of likely misappropriation.

Issue #2

Whether the worldwide, eight-month injunction was broader or longer than necessary to address McCain’s alleged head start.

Holding

No. Its geographic reach and duration were within the trial court’s discretion.

Reasoning

Trade-secret relief aims to protect confidential information and remove the unfair commercial lead gained through misappropriation. The appropriate duration reflects how long legitimate independent development or reverse engineering would have taken, rather than merely the time until a patent issued.

Restricting the injunction to countries where Lamb-Weston already sold its fries would not remove that advantage. Lamb-Weston sought to enter new markets, while McCain had a more established distribution system; sales anywhere could let McCain profit from its head start and foreclose those opportunities.

Testimony indicated that developing the blade’s materials, dimensions, and fabrication process took Lamb-Weston about a year and a half. The later patent disclosure did not make the blade’s undisclosed specifications, materials, and manufacturing process public or erase an advantage from earlier misuse. On that record, an eight-month injunction was not an abuse of discretion.
