Polymicro Technologies and InnovaQuartz Resolve Inner-Lok™ Patent Dispute

Phoenix, Arizona, USA, Dec 2, 2003– Polymicro Technologies, L.L.C. announced today that the patent lawsuit with Innovaquartz, Inc. involving the production of Polymicro’s Inner-Lok™ connectors has been resolved and all claims have been dismissed. In the lawsuit, Innovaquartz alleged that Polymicro was infringing U.S Patent No. 5,512,078, which Polymicro denied. Polymicro will continue to manufacture and provide to its customers the same high quality Inner-Loks made by the same proven method without restriction or royalty.

The Inner-Lok™ is Polymicro’s trade name for a press fit connector, or splice, used for coupling of the silica capillary tubing used in gas chromatography. Polymicro, the world’s leading supplier of such capillary tubing, supplies the Inner-Loks manufactured by its own proprietary process. According to Joe Macomber, Separations Science Manager at Polymicro, “The technology for producing Inner-Loks originated at Polymicro, and we have further developed our technical capability in this area. From the inception of this lawsuit we were confident of our position and we will continue to manufacture Inner-Loks. Polymicro provides a quality product that has been readily accepted in the marketplace”. Polymicro plans to further expand its product line of capillary tubing coupling products in 2004.
