STAMFORD, Conn., June 4, 2001-- The U.S. Court of Appeals for the Federal Circuit has ruled that Xerox Corporation (NYSE: XRX) did not infringe a patent that was held by AccuScan Inc. The court, which hears all patent appeals for all U.S. District Courts, reversed a district court's judgment for AccuScan that would have amounted to $16 million in royalties and interest payments. The Court of Appeals ruled that Xerox has no liability to AccuScan. "This ruling confirms that AccuScan's patent infringement claim was without merit," said Christina Clayton, Xerox general counsel. "Our policy is to vigorously defend ourselves at trial and through all levels of appeal against patent infringement claims when we believe those claims have no merit." Donald R. Dunner, of Finnegan, Henderson, Farabow, Garrett & Dunner, argued the appeal on behalf of Xerox. AccuScan first sued Xerox in April 1996, alleging that Xerox infringed on its patent and included its technology in certain Xerox fax machines, scanners and copiers.
