The court drama between Jawbone and Fitbit is heating up quickly. Two weeks ago Jawbone sued Fitbit for "plundering" confidential information (along with employees), now Jawbone is topping that off with another lawsuit centered on patent infringement. And it's going an extra mile this time: the Up fitness band maker is also trying to stop shipments of Fitbit's products in the US by bringing the matter to the International Trade Commission. Specifically, Jawbone says Fitbit infringed on its patent that details "a wellness application using data from a data-capable band." On the face of it, though, that seems like something just about every wearable maker is doing. Still, this can't be good news for Fitbit, which is currently preparing to go public on the stock market.
