Paulsson Geophysical Servs. Inc. v. Sigmar, 07-50406

Grant of a preliminary injunction in order to prevent defendant from using plaintiff's trademarks and other proprietary information is affirmed where: 1) the court had proper subject matter jurisdiction since defendant's activities had a substantial effect on U.S. commerce under the Lanham Act; 2) defendant used plaintiff's exact marks, supporting the court's finding of a likelihood of confusion; 3) plaintiff would have been irreparably harmed if defendant would have been allowed to work using plaintiff's mark.
