LG Electronics Joins Via Licensing's Program Offering a Joint Patent License for IEEE 802.11 Standard

Joint license available from six leading intellectual property owners; program extends incentive period for early signing licensees

San Francisco, July 26, 2005—Via Licensing Corporation is pleased to announce the addition of LG Electronics as a licensor in its joint patent licensing program that offers a license for patents that are essential for implementation of the IEEE 802.11 family of standards as defined in the patent license agreement. LG Electronics joins France Telecom SA, Fujitsu Limited, Japan Radio Company Ltd., Koninklijke Philips Electronics NV, and Sony Corporation as licensors offering licenses jointly through the program.

In addition, the licensors have agreed to a onetime extension of the signing incentive period for licensees. As a result, the joint patent license now contains a provision that waives royalties for practice of the IEEE 802.11 Standard for the period prior to December 31, 2004 for companies that become licensees on or before August 11, 2005. Licensees signing after that date will be required to pay license fees back to the beginning of their sale of products compliant with the IEEE 802.11 Standard.

Joint licensing programs provide the market with a convenient and cost-effective way to obtain licenses to the patents essential to practice of the standard. By doing so, the programs encourage greater adoption of the standard. Without such a joint license, the process of providing and obtaining necessary licenses would be cumbersome and expensive for all parties. The patent license agreement grants a license to all patents owned or licensable by the licensors that are essential to practice of the standard. As additional licensors join the program, the license fees do not change.

The IEEE 802.11 Standard is an internationally published open standard that defines a range of methods for providing wireless local area networking services. IEEE 802.11 networking is flexible and convenient. In homes, businesses, and public places, wireless networks can be established to provide connectivity to the wider world. IEEE 802.11 devices combine portability, mobility, and high data rates to bring networking to more places than it has ever been.
