The closest thing I've found is a Linux Journal article written by Earl Boebert, http://www.linuxjournal.com/article.php?sid=4963, entitled "Some Thoughts on the Occasion of the NSA Linux Release". He writes that "The NSA release incorporates an idea called Type Enforcement (TE) that was cooked up by Dick Kain and [himself] over 15 years ago" (this article is dated Jan. 24, 2001). There is no mention of a patent, but a search at the US PTO web site, http://patft.uspto.gov/netahtml/search-bool.html, shows three granted in the mid eighties to Mr. Boebert, et. al, #4621321, #4701840, and #4713753. I'm not sure if any of these are the relevant ones or not, though, after a quick glance, they appear to be. There is another Linux Journal article, http://www.linuxjournal.com/article.php?sid=5105, entitled "Secure Computing to Develop Type Enforced Tux", dated Feb 23, 2000, which refers to SCC's "patented security solution for the Linux kernel". At the end it refers to the "lingering question" of "the origins of the Type Enforcement technology." I'm not sure why this is a "question", but it notes that SCC used the University of Utah/NSA Flask system/modified kernel "for the current Type Enforcement/Secure Linux project", and that the origins of Type Enforcement "may go back as far as the 1970s" referring to PSOS.
