By studying the patents of Wireless Local Area Network(WLAN), then comparing with the upcoming one of IEEE 802.11n and IEEE 802.16, we have come to recognize some fundamentals that make it stand out as a dominant for technical and patent strategy for the R&D. These fundamentals are summarized as follows: The ratio of patent indicated in the WLAN standard is low. And the method of signal transmission, network and data moving is the main claim in the IEEE 802.11a/b/g patents;while the new trend of patents of IEEE 802.11, 802.16 emphasize the network topology and QoS, that our R&D cannot ignore. Further, the key profit owned by Intersial, Agere, and Broadcom in the WLAN chipset area. So, it’s important to attend the new technical and standard develop group, and to join the international licensing group to reduce the patent suit. For the IEEE 802.11n, 802.16, we should put more effort inside, and gather the update technical and trend information to be the base line of new R&D technology. Finally, for those who want to direct the formation of a standard and get the tremendous potential profits from it, they will do a lot of lobbying and form strategy alliances to attract more supports for the standard. To avoid patent suit, the IEEE should call for all standard-supporting companies to claim all relate patents in advance.
