Dutch technology company Nonend Inventions NV has issued proceedings in the US against Spotify, claiming that the streaming music platform is infringing a number of its patents. In the lawsuit, Nonend, which says it specialises in peer-to-peer and online streaming technology, accuses Spotify of “making, using, offering to sell, and selling streaming music services to users which incorporate methodologies that infringe” it’s intellectual property.  The streaming service is yet to respond to Nonend’s litigation.
