The wearable fitness tracker war has taken a new turn with Jawbone filing a counterclaim against rival Fitbit in a patent infringement case.
Fitbit initiated battle in September, but in the countersuit Jawbone denies Fitbit’s infringement allegations, calling them frivolous.
Now Fitbit alleges Jawbone infringes three of its patents, but Jawbone says the claims have no merit.
Jawbone is continuing to pursue three of its own prior legal actions against Fitbit over its own claims of patent infringement; stolen trade secrets; and an ITC injunction.
Both companies are facing a fresh wave of competition from established brands such as Apple’s Watch and Microsoft with its fitness tracker Band.
