The decision of the Court can be appealed to the Court of Appeals for the Federal Circuit, the centralized appellate Court for patent appeals in the United States. Background On December 30, 1999, the U.S. District Court for the District of Delaware announced its decision in the patent dispute between Biacore and Thermo. The Court decided in Biacore's favor, holding that Biacore's patent was valid and that the patent had been infringed by Thermo's Affinity Sensors unit. The Court further indicated that it "would grant a permanent injunction preventing Thermo from infringing the '161 patent' and requested further briefing regarding the amount of damages to be paid by Thermo for its past infringement and concerning the language of the permanent injunction. The Court's April 23, 2001 Judgment addressed these outstanding issues. - Ends - This press release contains certain forward-looking statements within the meaning of the United States Private Securities Litigation Reform Act of 1995, which, by their nature, involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future.
