QuadTech Drops U.S. Patent Infringement Lawsuit, Continues Suit Against Q.I. Press Controls

"First, our patent (U.S. Patent No. 5,412,577) for positioning the camera over a region of interest expired 18 months after we filed the suit.

"Second, QIPC has only recently begun to provide substantial responsive information in the case, and we have concluded that there has been only a single infringing sale in the U.S.—and none since the filing of the lawsuit, meaning that there are relatively minimal damages. With the patent now expired, and given the high cost of patent litigation and the complexities of this case, it is not financially reasonable for QuadTech to continue to pursue this litigation."
