25 tech firms sued for breaching 3G patents -

A case started in a Delaware district court by Golden Bridge Technology lists 25 tech firms alleged to breach a number of 3G patents.

The defendants in the case are T-Mobile, Deutsche Telekom, Amazon, Acer, Barnes & Noble, Dell, Garmin, Hewlett Packard, HTC, Exedea, Huawei, Lenovo, LG Electronics, Novatel, Option NV, Palm, Panasonic, Pantech, Research in Motion, Sharp, Sierra Wireless, Sony, Sony Ericsson, UTStarcom and ZTE.

Golden Bridge Technology (GBT) alleges these companies have all breached patents relating to standards for 3G wireless comms, including devices and base stations. The defendants, the filing says, have refused to license the patents. These patents are 6,574,267 B1, and 7,359,427.

GBT said that it has contributed to the telecommunications standards with the patents related to 3G networks that use UMTS. Together with AT&T, it developed a wireless multimedia service using Code Division Multiple Access (GB-CDMA) and co-chared standardisation committees.

It claims that many of its developments were adopted by 3GPP “as an important and necessary part of the 3G and UMTS standards”.  All of the defendants, in one way or another, use GBT’s technology, it alleges. GBT is seeking damages from each of the defendants’ alleged past and present infringement. In addition, it wants treble damages against T-Mobile, HTC, LG, Palm, RIM and Sony Ericsson, and lawyers’ costs.
