If the name Intellectual Ventures (IV) sounds familiar, thats because the firm went on a suing spree over patents a few years ago. One of them, a two-year-old lawsuit against Motorola, finally went to court last month, but its already hit a snag: the judge just declared it a mistrial. The trial revolved around three smartphone technologies, including one at odds with Google Play, but the jurors have failed to reach a unanimous vote.
