Macrovision Corp. has sued two companies it claims offer products that break its patented copyright protection technology and allow consumers to make unauthorized duplicates of commercial DVDs. In the suit filed Tuesday in New York, Santa Clara, Calif.-based Macrovision said the companies — Sima Products Corp. and Interburn Enterprises Inc. — infringe on its patented copy control technology and also violate the Digital Millennium Copyright Act. “The Sima and Interburn products have very limited commercial uses other than to circumvent Macrovision’s copy protection technology and are marketed by Sima and Interburn for use in copying DVDs, among other types of media,” Macrovision CEO Bill Krepick said. The suit is seeking an order to halt the sale of Sima and Interburn products. Sima, which is based in Oakmont, Pa., has not been served with a lawsuit and declined to comment, said Kathy Ruane, Sima’s marketing manager. The company learned of the lawsuit from reporters, she added. Sima has been selling duplication tools for the past eight to 10 years, she added. “We have had correspondence back and forth with Macrovision _ our lawyers and their lawyers,” she said. “As far as we knew, it was correspondence.” Interburn did not return an e-mail message seeking comment. The company, according to its Web site, offers DVD X Copy, a program that allows copyright protected DVDs to be duplicated. Missouri-based 321 Studios Inc., which created the program, lost several rounds in federal court and eventually retooled the software last year to remove the mechanism that cracked the copyright protection mechanism built into commercial DVDs. Interburn offers older versions of the 321 program. Copyright 2005 Associated Press. All Rights Reserved. This material may not be published, broadcast, rewritten, or redistributed.
