VANCOUVER, B.C.--Sept. 17, 2001--The United States District Court for the District of Delaware has ruled in favor of Creo Products Inc. in the two-year-old patent dispute with Presstek, Inc. (Presstek) of Hudson, New Hampshire. This dispute centered on the on-press imaging technology sold through CreoScitex, the graphic arts division of Creo. The court determined that the printing presses using Creo's imaging technology do not infringe the patents-in-suit. The court affirmed that neither Creo's imaging technology, nor printing presses that use Creo's imaging technology, infringe Presstek's patents. "We are pleased to see that the court has confirmed the uniqueness of our imaging technology and that our technology does not infringe Presstek's patents. We believe that intellectual property rights anchor our competitive position,'' said Dan Gelbart, Creo's President and Chief Technology Officer, and inventor of the SQUAREspot(TM) thermal laser imaging device. "Over the past six years, the outstanding performance of our unique SQUAREspot imaging heads has led to our strong leadership position in the computer-to-plate (CTP) marketplace with more than 3000 CTP machines installed-by far the largest installed base of any CTP design.'' Since commercial shipments of the on-press version of this product began in 1999, more than 500 SQUAREspot imaging devices have been put into use on digital offset printing (DOP) presses located at commercial printers around the world. "The high speed and outstanding image quality enabled by Creo SQUAREspot technology resulted in the world's three largest press companies selecting our system for their high-end DOP presses-the Heidelberg Speedmaster 74 DI, the Komori Project D and the MAN Roland DICOweb,'' said Brad Palmer, Corporate Vice President of On-Press Technologies at CreoScitex. "We appreciate the court's recognition of our technology and at the same time, we acknowledge Presstek's contribution in helping to develop the on-press imaging market.'' The September 11, 2001 ruling by United States District Judge Gregory M. Sleet followed a five-day trial in the United States District Court for the District of Delaware in June 2001. 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 CreoScitex customers and prospects that Creo infringed Presstek patents. Presstek counter-sued and the Court combined the two cases.
