[Nomentatus]

This is common stuff, and good luck on prompt action! No, I wasn't working for a prof - but note that you yourself just accept that work including ideas can be published by a prof without attribution to the discoverer! That tells us all where the academic mindset is. My noting is your whining, I gather. One can't tarry on life's path to upbraid all the assholes in the world, and legal redress is well out of reach of most of us. One can note it to warn others, and move on.
