Waters Receives $17.4 Million Payment from the Applera Corporation in Thermal Analysis Patent Infringement Case

MILFORD, Mass.--(BUSINESS WIRE)--May 13, 2004--Waters Corporation (NYSE/WAT) announced today that it has received payment of damages of approximately $17.4 million from the Applera Corporation (successor to the Perkin-Elmer Corporation, the named defendant in the action) as a result of a judgment in favor of the Company in a patent infringement case involving three TA Instruments MDSC(R) patents (U.S. 5,224,775; 5,346,306 and 5,439,291). The case, originally filed in 1995, dealt with patents that describe designs embodied in differential scanning calorimeter (DSC) products, important instruments for the analysis and characterization of high performance polymers, pharmaceuticals and other materials. In October 2002, a jury found Perkin-Elmer liable for infringement of all three patents and judgment was entered in favor of the Company in May 2003. On May 5, 2004, the United States Court of Appeals for the Federal Circuit affirmed the District Court's judgment.

Waters Corporation holds worldwide leading positions in three complementary analytical technologies - high performance liquid chromatography (HPLC), mass spectrometry (MS) and thermal analysis (TA). These markets account for $4.4 billion of the overall $20 billion analytical instrument market. TA Instruments Inc., headquartered in New Castle, Delaware, is a wholly owned subsidiary of Waters Corporation.
