Patent troll or maligned inventor?

A company called Post Media Systems is suing Spotify and iHeartMedia for patent infringement. Post Media Systems claims that they have patents covering a system for sharing and retrieving playlist information on the Internet. The patents were taken out by inventor Alan Bartholomew, and supposedly “resolve technical problems related to a specific functionality of computers and networks (e.g. Internet or other networks) to post, share, and play back media, overcoming posting and interface issues specific to different computing systems and accounts on shared networks.”
