Tapp MFG, Inc. v. Speed UTV, LLC

1:24-CV-944 · United States District Court for the Middle District of North Carolina · January 27, 2026 · No. 1:24-cv-00944

Summary

The United States District Court for the Middle District of North Carolina addresses Tapp MFG, Inc.’s motion for a preliminary injunction in a patent infringement action against Speed UTV, LLC. The court preliminarily concludes that the parties did not form an express patent license under their email exchange or subsequent draft agreements, and the motion is granted based on the court’s stated reasons.

Holdings

  1. Tapp sufficiently demonstrated for purposes of the preliminary injunction that Speed's clutch infringes the '695 patent, and Tapp was likely to prove infringement after termination of the implied license.
  2. The November 4, 2020 email exchange and subsequent draft agreements did not create a binding express license because the parties did not mutually assent to the same essential terms.
  3. The parties' entire course of conduct created an implied license for Speed to use the clutch design covered by the '695 patent.
  4. Speed did not raise a substantial question that would defeat Tapp's likelihood of success on patent validity or enforceability.
  5. Tapp established all four requirements for preliminary injunctive relief: likelihood of success, likely irreparable harm, a favorable balance of equities, and consistency with the public interest.
  6. Tapp was required to post a nominal $10,000 bond as a condition of the preliminary injunction.

Questions Presented

  1. Whether Tapp was likely to prove that Speed infringed U.S. Patent No. 12,104,695.
  2. Whether the parties' communications and conduct created an express or implied license to practice the patented clutch design.
  3. Whether any implied license had been terminated.
  4. Whether Speed raised a substantial question concerning the validity or enforceability of the patent.
  5. Whether Tapp demonstrated irreparable harm, a favorable balance of equities, and that a preliminary injunction would serve the public interest.
  6. What bond was appropriate under Federal Rule of Civil Procedure 65(c).
