ADT Security , providers of Sensormatic Electronic Article Surveillance (EAS) solutions, have announced a victory in a major lawsuit against a competing company that was found liable for patent infringement, misappropriating trade secrets and employing unfair trade practices.

The lawsuit involved ADT Security’s Sensormatic anti-theft solutions which protect retailers from shoplifting and internal theft.

The U.S. District Court, Southern District of Florida immediately prohibited ‘The Tag Company’ from making or selling any of their products in the U.S. that were produced using confidential information about patent-protected Sensormatic products. This includes ‘The Tag Company’s’ Series 58 acousto-magnetic label. The ruling also prohibited ‘The Tag Company’ from distributing the Series 58 label from the U.S. to anywhere else in the world.

In the suit, a federal court found that several former Sensormatic employees, who helped design, develop and market Sensormatic EAS systems, had misappropriated and improperly used important proprietary information about those products to benefit ‘The Tag Company’.

The court also ordered ‘The Tag Company’ to pay damages and ruled that one of their consultants, a former Sensormatic engineer who previously helped develop Sensormatic technology, violated his prior employment agreement by misusing confidential information. The court ordered the man to pay costs and attorney’s fees.
