A federal jury in Texas on Monday found that HTC, Sony, Ericsson and Alcatel-Lucent do not infringe Wi-Lan’s technology, The Wall Street Journal reported. Wi-Lan, a well-known patent troll that uses litigation to generate revenue, had accused the companies of infringing on four of its wireless patents. The company previously filed a similar lawsuit against BlackBerry in December. A Wi-Lan spokesperson told The Journal that the company was “disappointed with the jury’s decision,” and it is now reviewing its options. Shares of Wi-Lan fell more than 30% to a three-year low of $3.27 on Monday, however they rebounded on Tuesday, jumping 13% to $3.70 per share.
