HOUSTON, March 25, 2008 (PRIME NEWSWIRE) -- Satellite Tracking of People LLC (``STOP''), the owner of BluTag(r), a GPS-based ``one-piece'' offender tracking and reporting system, announced today that it filed a patent infringement action against Omnilink Systems, Inc. (Alpharetta, GA), ProTech Monitoring, Inc. (Odessa, FL), a subsidiary of Israeli-based DMATEK (LSE:DTK.L - News), and SecureAlert, Inc. (Salt Lake City, UT), a subsidiary of RemoteMDx (OTC BB:RMDX.OB - News), in the United States District Court for the Eastern District of Texas.

STOP's federal complaint alleges infringement of U.S. Patent No. Re 39,909, entitled ``Tracking System for Locational Tracking of Monitored Persons,'' by Omnilink with its one-piece OM 200 device and system, by ProTech with its one-piece MTD3000 SMART(r) One Wearable Miniature Tracking Device and system, and by SecureAlert with its one-piece TrackerPAL device and system. The complaint seeks a permanent injunction prohibiting Omnilink, ProTech, and SecureAlert from continuing to offer in the United States their unlicensed one-piece locational tracking products.

According to Steve Logan, STOP's CEO, ``The BluTag(r) system is a pioneering technology in the field of locational tracking of monitored persons. STOP has made substantial prior and ongoing investments to license, develop and deploy this proprietary technology as a system that today best meets the needs of our customers. The intellectual property associated with our BluTag(r) technology is an integral asset of our company, and one we intend to vigorously enforce as STOP continues to expand its presence in the GPS offender tracking arena.''
