Trimble, suppliers of GPS systems, has filed suit against TracerNet Corporation of Chantilly, Virginia in the US District Court for the Eastern District of Virginia for alleged patent infringement.
The complaint alleges that TracerNet is violating US Patent No. 6,611,755 issued to Trimble on August 26, 2003. The patented auto-status technology is used in Trimble’s Telvisant Fleet Management System for the ready-mix concrete market.
Trimble’s Telvisant Fleet Management System identifies the location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager.
The system automatically reports a variety of programmable events that are common in the ready-mix concrete market, such as ‘leave plant,’ ‘arrive at job site,’ ‘pour begin,’ ‘pour end,’ ‘leave job site,’ ‘water added’ and ‘return to plant’.
Trimble is seeking a permanent injunction precluding TracerNet from infringing Trimble’s patent as well as monetary damages for past infringements.
Trimble’s patent in suit was filed on December 19, 1999, more than one year prior to the filing of a related US patent 6,496,775, which has been issued to TracerNet. Trimble intends to ask the US Patent & Trademark Office to re-examine this TracerNet patent based on Trimble’s patented technology.
