VANCOUVER, British Columbia--Sept. 18, 2002--Creo Inc. is pleased to announce that the United States Court of Appeals for the Federal Circuit affirmed that Creo's on-press imaging technology for digital offset presses does not infringe the patents in suit. In the Court of Appeals' judgment issued on September 17, 2002, the judgment on appeal from the United States District Court for the District of Delaware was affirmed in all respects holding that the Creo on-press imaging system does not infringe the Presstek, Inc. patents, with a dissenting opinion that one of the Presstek patents should be found invalid. "We are pleased to see that the Court has reconfirmed the uniqueness of our imaging technology and that our technology does not infringe Presstek's patents," said Dan Gelbart, Creo president and chief technology officer. "We look forward to continued success in our DOP (digital offset printing) Imaging System business and to supplying our partners with our DOP kits." Creo originally filed suit on August 12, 1999 requesting that the Court rule that the Creo technology in question did not infringe or induce pressmakers to infringe Presstek patents, after accusations by Presstek to Creo customers and prospects that Creo infringed Presstek's patents. Presstek counter-sued and the Court combined the two cases.
