Carl C. Jacobson, Jr., E.j. Johnson and Internationalsurfacing, Inc., Plaintiffs-appellees, v. Cox Paving Company, Defendant-appellant,andgranite Construction Company and Achen-gardner Company, Defendants, 949 F.2d 404 (Fed. Cir. 1991)

Cox Paving Company appeals from the judgment of the United States District Court for the District of Arizona, No. 89-1786 (May 16, 1991) which granted Jacobson's motion for a preliminary injunction under Fed. R. Civ. P. 65(a). The District Court enjoined Cox from infringing Patent Nos. 3,891,585 and 4,069,182 owned by Jacobson, finding a likelihood that Jacobson would succeed on the merits on the issues of validity, enforceability and infringement of its patents, and similarly finding irreparable harm to Jacobson absent the injunction, a balance of hardships favoring Jacobson and public interest weighing in favor of the injunction's imposition. We affirm.

OPINION

In Chrysler Motors v. Auto Body Panels of Ohio, Inc., 908 F.2d 951, 15 USPQ2d 1469 (Fed. Cir. 1990), this court set out the standard by which it reviews preliminary injunction appeals in the patent context. The court stated that the grant of a preliminary injunction "lies largely in the sound discretion of the trial judge.... We review the trial judge's determination to ascertain if there was an abuse of discretion, an error of law, or a serious misjudgment of the evidence." Id. at 953, 15 USPQ2d at 1471 (citations omitted). In light of this standard, we find that Judge Rosenblatt, in his thorough and well-reasoned opinion, did not abuse his discretion, but instead carefully weighed the evidence and properly granted the preliminary injunction.
