There are a hell of a lot of patents regarding SLS, most of which are active for quite a while yet.

I believe some patent on SLS from the University of Texas expires in 2014 or end of 2013 or sometime, but I can't seem to find anyone specifying what exact patent is being talked about. Of the 3 patents U of T got in 1994, I believe they're talking about #5,296,062 "Multiple Material Systems For Selective Beam Sintering".
