LeafFilter North, LLC, et al. v. Curtis Marshall

LeafFilter · United States District Court for the Northern District of Ohio, Eastern Division · January 14, 2026 · No. 5:26-cv-44

Summary

The United States District Court for the Northern District of Ohio grants LeafFilter North, LLC and related plaintiffs’ motion for a temporary restraining order against former executive Curtis Marshall. The court concludes that plaintiffs demonstrated a strong likelihood of success on breach-of-contract and trade-secret misappropriation claims based on Marshall’s restrictive covenants, access to confidential information, and employment with a competitor. The court also finds likely irreparable harm and that the restrictive covenants are likely enforceable under Ohio law.

Holdings

  1. Plaintiffs demonstrated a strong likelihood of success on their breach-of-contract claims because Marshall signed agreements containing restrictive covenants, joined a direct competitor in a similar executive position, and possessed knowledge of Plaintiffs' sales strategies and operating methods used across multiple home-improvement markets.
  2. At the temporary-restraining-order stage, the restrictive covenants were likely enforceable under Ohio law because they were likely no greater than necessary to protect Plaintiffs' legitimate interests, did not likely impose undue hardship on Marshall, and were not likely injurious to the public.
  3. Plaintiffs demonstrated a likelihood of success on their DTSA and OUTSA claims by showing that Marshall possessed or had access to confidential information and trade secrets and that threatened misappropriation was likely because he entered a substantially similar position with a direct competitor.
  4. The four temporary-injunction factors supported relief because Plaintiffs faced irreparable harm from potential disclosure and unfair competition, enforcement would not foreclose Marshall from all employment, and contractual enforcement and prevention of unfair competition served the public interest.
  5. No bond was required because the court found no proof of likely harm from wrongful restraint sufficient to warrant security.

Questions Presented

  1. Whether Plaintiffs established a strong likelihood of success on their breach-of-contract claims based on Marshall's alleged violation of restrictive covenants.
  2. Whether the restrictive covenants were likely enforceable under Ohio law because they were no greater than necessary to protect legitimate business interests, did not impose undue hardship, and were not injurious to the public.
  3. Whether Plaintiffs established a likelihood of success on their federal and Ohio trade-secret misappropriation claims based on actual or threatened misappropriation and inevitable disclosure.
  4. Whether Plaintiffs established irreparable harm, favorable balancing of harms, and a public interest supporting a temporary restraining order.
  5. Whether a bond was required as a condition of temporary injunctive relief.
