In this case, UTTO Inc. sued Metrotech Corp. for infringement of a patent related to detecting buried assets, and for tortious interference with prospective economic advantage. The district court dismissed both claims. The appeals court vacated the dismissal of the patent infringement claim, finding the district court's claim construction insufficient and requiring further analysis. However, the appeals court affirmed the dismissal of the tortious interference claim due to insufficient allegations of wrongful conduct by Metrotech.
