Yes, the next MP3 patent expires this Sunday. The longest patent seems to expire in 2018 but that appears to be MPEG-2 LSF and only required for low sample rate MP3s. So the next furthest date looks like April 2017 but it may be worth double checking the dates on those around 2014/2015.

As far as the Vista stories go, the network/copying/audio issues had to (or were believed to at the time) do with the DRM laden audio chain.
