" University of Illinois v. Andreessen (1994) - The web revolution began at the University of Illinois with the first graphics based browser, Mosaic, but few are aware of its history. The open source code which spawned both Netscape and Internet Explorer was created by graduate students using open source code. The university sued the students for trademark infringement in an attempt to capture royalties even though the source code was available for free on the web. The developers offered the university shares in the newly launched Netscape which would have netted UL over $8 million. Instead, the university chose a prolonged legal battle which was settled for $2.7 million, bankrupted Netscape, allowed Microsoft Explorer to capture the browser market and left University of Illinois out of the legacy of the innovation.

That said, I think public university research should all be public domain so we avoid this entirely, but there's a whole waterfall of other problems that come with that.
Also, as a graduate of UIUC, I'm curious about this bad rep. I know their entrepreneurship initiatives are pretty dismal but I still don't understand why that's a uni's job. All the cs/engineers that graduated when I did went straight into great jobs.
