Groklaw is still very useful. I don't find the legal analysis itself all that useful, but it usually links to primary sources that I can analyze myself.

I'm not a lawyer, but when I got burned out on programming I took a break and went to law school with the intent of going into IP and corporate law. After the final year, I had one paper to complete for an IP seminar to get the degree, and intended to write it over the summer. However, I went back to my old programming job as a summer, found that my programming mojo was back and stayed, and never got around to finishing that paper!
