Andy Rubin's Essential Products is facing more legal troubles. The ex-Android chief's company previously found itself in hot water with smartphone accessory maker Spigen over its use of the "Essential" name. Now -- less than two months since the release of the Essential Phone -- it's getting sued for allegedly stealing trade secrets relating to its modular connector, reports Reuters. Keyssa, the company behind the lawsuit, is best known for developing a wireless standard that lets you make gigabit-sized transfers in seconds. Its backers include Nest co-founder Tony Fadell, Samsung, and Playground Global (the venture fund Rubin heads).
