Patents on cognitive radio over TVWS

Cognitive Radio Patents. At the beginning of the year I wrote a post about the companies with most patents on cognitive radio. In that 1st quarter of 2010 the three leading companies in number of patents were1 Motorola (14%), Samsung (14%) and Qualcomm (8%).

A recent survey shows the patent scenario for the last quarter, now focused on cognitive radio patents for the television band (TVWS). The results are very similar to the previous post and only the order of the three leading companies has changed. Samsung Electronics leads in number of patents related to cognitive radio over TVWS, followed by Motorola, and Qualcomm. While the quality of several of these patents is doubtful, it is true that usually exists certain correlation between the number of patents and the actual innovations developed by a certain company.
