The updated lawsuit also tries to clarify the charges and elaborate on what happened. Where Jawbone first accused its ex-staff of having 18,000 pertinent files, the discovery process suggests that there were "at least" 335,191 files involved. Jawbone says that the files include everything from schematics through to manufacturing prices and schedules. New Fitbit gear like the Alta supposedly incorporates stolen Jawbone tech, it adds. With that said, it's doubtful that many of the new files actually contain sensitive info -- Jawbone required that an employee maintain a cloud backup containing all those extra files, and many of them are likely system files irrelevant to the case.

Fitbit isn't having any of this. The firm contends that it had already revealed the existence of those files back in December, and that the expanded number of files was only reflecting what had been known for months. When we reached out, Fitbit told us that the motion for an amended complaint is an act of "desperation" by Jawbone in response to both its losses at the International Trade Commission and its poor competitive performance. You can read the full statement below. Not that this was entirely surprising, either way. Fitbit took its own legal action against Jawbone in September, and it has long contended that Jawbone was trying to compensate for being an also-ran in the activity tracker world. You'll probably only see one side concede when there's no other choice, and that likely won't happen for a while yet.
