Presstek Sues VIM Distributor Prograf for Patent and Trademark Violations

HUDSON, NH—January 15, 2009—Presstek, Inc. today announced that it has filed a lawsuit in United States District Court in New Hampshire against a distributor of printing plates manufactured by Israeli company VIM Technologies, Ltd. The Complaint alleges that Prograf Digital Services, Inc. and its President Joseph Musgrave violated Presstek’s rights by selling VIM printing plates, which Presstek alleges infringe Presstek’s U.S. Patent Nos. 5,339,737 and 5,487,338. Presstek also claims that Prograf and Musgrave have violated Presstek’s federally registered DI Trademark, which Presstek has held since 1992.
