An anonymous reader cites an article on The Register: Yieldify, the Google-backed startup accused of stealing code from British adtech company Bounce Exchange, has been making some unusual friends. Yieldify has acquired an ancient web patent from III Holdings which was first filed in 2007. III Holdings is better known as Inside Intellectual Ventures, co-founded by Nathan Myhrvold. It has been dubbed "the most hated company in tech" and "the world's biggest patent troll." IIV is a "NPE" (non-practicising entity), which gathers up patents and seeks to unlock their value through selling on or licensing the IP. This has been backed up by litigation, such as Samsung, a recipient of one of III's sueballs. In a court filing made last week, Yieldify made a request for declaratory judgement in its ongoing case versus Bounce Exchange, citing the IIV patent. Also from the report: Clearly, patent trolls are unacceptable when they're trolling you, but become strategically useful when you can troll back.
