Jawbone and Fitbit legal fight gets uglier. The two wearable technology companies are embroiled in a dispute over intellectual property. In the latest twist, Jawbone is accusing Fitbit of antitrust violations that are "part of its by-any-means-necessary campaign to impede competitors and preserve its dominant position in the fitness-tracker market." Meanwhile, Fitbit is asking the International Trade Commission to halt certain Jawbone imports, citing patent infringement. ( Wall Street Journal )
