Fitbit is fighting back Jawbone, having filed a suit against the UP band maker and its subsidiary, BodyMedia, in Delaware District Court, for alleged patent infringement.

The world’s biggest activity tracking device maker alleges that Jawbone has infringed on three of its patents, including two issued in May 2015 – “Notifications On A User Device Based On Activity Detected By An Activity Monitoring Device,” and “Biometric Monitoring Device With Heart Rate Measurement Activated By A Single User Gesture,” and the third, “Methods for Detecting and Recording Physical Activity of Person,” issued in December 2014. Fitbit claims Jawbone’s UP Move, UP24, UP2, UP3, and UP4 as well as the UP software infringe on these patents.

The Fitbit-Jawbone saga began in May, when Jawbone alleged that Fitbit poached employees who on their end downloaded sensitive data before leaving the company. That first lawsuit was unveiled just a few weeks after Fitbit has filed for an IPO.

A month later, Jawbone filed a second lawsuit against Fitbit, alleging infringement of three of its patents that were owned by its subsidiary, BodyMedia.

Finally, in July, Jawbone has filed a complaint with the US International Trade Commission to block Fitbit’s imports into the US based on the two lawsuits against Fitbit.
