Mainland Industries, Inc. v. Timberland MacHines & Engineering Corp.

Plaintiff Mainland Industries, Inc. (Mainland) appeals from a trial court decree that (1) ordered defendant Miller to assign a patent to Mainland, but allowed Miller a lifetime license in the patent, and (2) denied Mainland’s prayer that a constructive trust be imposed on any profits earned by defendants as a result of their wrongful use of the disputed patent. Defendants cross-appeal, contending that the trial court erred in holding that Mainland owns the patent and in holding that certain documents in defendants’ possession belong to Mainland. We review de novo.
