Jawbone is suing its archrival, Fitbit, for "systematically plundering" confidential information. According to the complaint, Fitbit recruiters attempted to poach almost one-third of Jawbone's staff. Some of those employees left the company, but not before downloading "critical trade secrets" including business plans and product details. The accusation comes right on the heels of Fitbit's decision to go public. The company, which sold 10.9 million wearable devices last year, filed for an IPO of up to $100 million earlier this month.
