After Xiaomi, now its OnePlus to take a major blow in India. Delhi High Court has banned OnePlus from importing marketing and selling devices in India. This time Micromax has directly sued the Chinese debutant over infringement of its exclusive rights over Cyanogen OS.

Micromax earlier ruined OnePlus launch party by exclusively licensing Cyanogen Inc in India. Cyanogen wasn’t upfront about the implications of this deal and after beating around the bush it finally admitted that this meant OnePlus units retailing in India won’t get any update in future.

Now Micromax has finally sought a ban on OnePlus from selling any Cyanogen based device in India, as it holds exclusive rights for Cyanogen in India. The ban comes shortly before Micromax is set to introduce its YU brand of smartphones in India.

Micromax YU phones will exclusively retail online and run CyanogenMod software. This makes YU phones a direct challenge to Xiaomi and OnePlus in India. Both brands are in legal trouble as of now.
