ADT Security Services, a Tyco International company, has had its patent lawsuit in China against ZhenTai Science & Technology Company upheld by a Chinese court.

ZhenTai was found liable of infringing upon ADT's Sensormatic anti-theft Ultra.Max label technology. The lawsuit involved acousto-magnetic labels manufactured by ZhenTai, which is located in Jingjiang, Fujian. ZhenTai offered its labels for sale both in China and for export abroad.

In its decision, the Quanzhou Intermediate People's Court enjoined ZhenTai from making, using or selling its infringing labels. Furthermore, ZhenTai was ordered to destroy any equipment, molds and drawings used to produce these labels and to pay nominal damages to Sensormatic.

This is the second court ruling in a year against a company infringing Sensormatic anti-theft label patents. In December 2008, a U.S. court found The Tag Company liable for patent infringement, misappropriating trade secrets and unfair trade practices.
