They bought BitTorrent Inc, the company: https://en.wikipedia.org/wiki/BitTorrent_(company) https://en.wikipedia.org/wiki/BitTorrent_(company) I'm not 100% sure but I think BitTorrent Inc may own some patents applicable to the BitTorrent protocol: https://www.theregister.co.uk/2013/11/04/bittorrent_awarded_distributed_storage_patent/ https://www.theregister.co.uk/2013/11/04/bittorrent_awarded_...
