Universities, the GPL and Patents?
nonlnear asks: "I'm about to finish a PhD in Mathematics and am starting to realize that I am not a big fan of my university's policy about inventions, patents, software, and the like. The gist of it is: you invent while working here => we own everything => we will patent everything. I am planning on a career in academia, but am very conflicted about this way of doing things. What Universities out there will allow me to publish (otherwise patentable) software under the GPL?"
The easiest way to force something under the GPL or other copyleft licenses is to make a derivative work from GPLed code. So consider using the GNU Scientific Library or something similar as your base. Your University will most likely not make you rewrite it and, if they have a legal department, will most likely not ask you to violate the GPL.
