After two years of litigation, Apple won a patent lawsuit case that concerned wireless technology. WiLAN, a patent-assertion entity, sued Apple in 2011, claiming the tech giant had infringed on patents that covered cellular wireless technology, but a Texas jury determined that Apple did not, indeed, infringe.

WiLAN was started in 1992 as a company that developed wireless technology, but in 2006, it transformed its business model into one that involved amassing patents and using them in leverage against large technology firms. This has caused some to label the company as a “patent troll.”

This case represents the third time WiLAN has sued Apple over patent infringement. In 2007, WiLAN filed a suit over Wi-Fi technology, and in 2010, it filed a separate suit over Bluetooth technology.
