Intellectual Ventures (IV) is one of the largest patent holders in the United States. Over the years, it has amassed tens of thousands of patents, which it has used to sue a number of companies for infringement, including Motorola and Bank of America. This type of behavior has led some to dub it a “patent troll.”
On April 11, 2014, Reuters reported that tech giants Microsoft and Sony have invested an undisclosed amount in the company. However, the same report notes that previous investors, Apple and Intel, have declined to invest in this round.
