Tenth Circuit Affirms Summary Judgment on Trade Secret Claims in Double Eagle v. Hooper

The Tenth Circuit recently upheld an Oklahoma District Court’s summary judgment ruling in favor of a trade secret defendant based on insufficient specificity as to the trade secrets at issue, as well as a lack of proper secrecy over those alleged trade secrets. The case, styled as Double Eagle Alloys, Inc. v. Hooper, included claims under the Defend Trade Secrets Act (DTSA), Oklahoma Uniform Trade Secrets Act (OUTSA), common law misappropriation, and civil conspiracy.

The Double Eagle plaintiff alleged that its former employee took sensitive files from the company when he left, including product quality specifications, pricing data, and customer drawings. The district court found that the plaintiff did not prove its materials warranted trade secret protection, including because it did not sufficiently differentiate protected from unprotected information. The court dismissed the common law misappropriation claim for lack of evidence of secrecy, and the civil conspiracy claim for the absence of an underlying tort.

The plaintiff appealed each of the district court’s bases for its ruling. But the Tenth Circuit affirmed the summary judgment order, ruling that Double Eagle did not meet its burden to show that its material warranted trade secret protection. In contrast, the defendants offered proof that they independently developed the same or similar product quality specifications, and that other material was readily ascertainable to the public. The Circuit Court also affirmed the trial court’s finding that the plaintiff failed to show what steps it had taken to keep its information secret, and many documents were already available through competitors or customers. Key information, such as pricing data and customer drawings, had been publicly disclosed or shared with third parties. The court also noted that the affidavits the plaintiff presented were conclusory and lacked specifics about the trade secrets or how they were safeguarded.

The ruling underscores the weight of the burden on trade secret plaintiffs to prove their entitlement to trade secret protections.
