60 GHz Wireless Systems Patent Landscape

60 GHz unlicensed band wireless systems, which can carry Gbps of data, enable several new applications: high definition video streaming wireless in real time, high speed wireless gaming, and wireless docking and connection to displays.

IEEE 802.11ad was formed in January 2009 to make industry standard for 60 GHz wireless systems as an amendment to the existing IEEE 802.11-2007 (modifications to the 802.11 PHY and the 802.11 MAC).

To find the technology innovation status of 60 GHz wireless systems, a keyword search of the USPTO patent data base has been performed. Total of 177 60 GHz wireless systems patents (38 issued patents and 139 published applications) in the US as of Feb. 28 2011 are identified.

Broadcom was the leader in the 60 GHz wireless system technology innovations followed by Samsung Electronics, Qualcomm, Intel, Nokia, NICT, and Toshiba.
