Technology firm sues 25 wireless companies over 3G patents

Golden Bridge Technology (GBT) is suing 25 technology companies, claiming the companies violate a number of its 3G patents for devices and base stations.

The defendants include T-Mobile, Deutsche Telekom, Amazon, Acer, Barnes & Nobel, Dell, Garmin, Hewlett Packard, HTD, Exedea, Huawei, Lenovo, LG Electronics, Novatel, Option NV, Palm, Panasonic, Pantech, Research In Motion (NASDAQ:RIMM), Sharp, Sierra Wireless, Sony, Sony Ericsson, UTStarcom and ZTE.

In its lawsuit, filed in Delaware, GBT claims it has contributed to mobile wireless standards with patents related to 3G networks that use W-CDMA. GBT said that it developed a wireless multimedia service, in conjunction with AT&T (NYSE:T), using CDMA and co-chaired standardization committees. GBT said all of the defendants use this technology in different forms.

GBT said its developments were adopted by 3GPP "as an important and necessary part of the 3G and UMTS standards." GBT is seeking damages from each of the defendants' alleged past and present infringement. In addition, it is asking for treble damages against T-Mobile, HTC, LG, Palm, RIM and Sony Ericsson, along with lawyers' fees.
