Beware the troll under the bridge
So let me get this right, on one hand we have IBM, mega tech global behemouth; winner of god knows how many awards for innovation; owner of a patent portfolio that must look like a good chunk of the Library of Congress; and with a budget that would embarass a small country.
And other the hand we have this backwoods outfit, who's sole revenue stream comes from throwing writs around. Heck, even their own website says that their product is merely "IP" rather than actual stub-your-toe-on-it real products. This shouts "patent troll" in 10 ft high neon letters!
I hope that IBM (unlike Hynix, Micro, Samsung et al) manage to deal them a good dose of the "SCO treatment" - i.e. replied; reveilled; and then ruined. :p
