Geez I hate patent trolling companies. Unfortunately, pretty much all the major guys do it these days - it's become necessary in big business as a defense mechanism (Don't sue me, or I'll sue you).
The irony is that patents are meant to be a mechanism to
encourage innovation by providing authors the right to benefit from their creations (thereby positively re-enforcing the creation of new content for the benefit of society) yet it seems all they are used for today in the corporate world is to
stifle innovation which ultimately harms society.
On a related note, if you are not supporting the Electronic Frontier Foundation (eff.org), you should be
NTP to sue American carriers
