OpenTV isn't a name on the tips of most consumers tongues. Neither is Kudelski SA, the company behind the video middleware platform, most commonly found on cable set top boxes. But brand recognition may increase now that the firm is taking streaming video giant Netflix to court. At issue are a collection of patents related to content delivery and DRM which Kudelski says Netflix has refused to license from it. The company now feels its only course of action is to take Reed Hastings and his crew to the mat in the U.S. District Court for the District of Delaware. Unlike some other markets we can think of, the streaming video field hasn't yet devolved into constant patent battles. But as more companies enter the fray, like Walmart and Amazon, there's a chance we'll see the number of courtroom brawls explode.
