Nope, just a nothing holding company. They purchase patents (paperwork) wait 10-15 yrs. till someone infringes, then sue! great business model don't ya think?
Actually there were founded by the late inventor Thomas Campana, who held the patents that are now in dispute. He held many patents (and actually made some inventions) but died before he could see how NTP and RIMM are behaving today.
I would make some snide jokes about NTP's web site, but then some lawyer would sue me.
