In an interesting addition it looks like Personal Web Technologies was recently involved in an acquisition that resulted in these patents changing hands.
"PersonalWeb has been working closely with the University of Texas at Tyler and other
community participants to develop products in the search, social network and content
filtering technologies.
BDE CEO Kevin Bermeister said, “We are excited by this next phase in the business and are
looking forward to working with PersonalWeb to pursue development, licensing and
participation in businesses that use our patents for content addressable storage, cloud
computing, search, social networking and other important developing technologies in the
rapidly growing distributed computing category.”
