You don't need to care about the particulars of the case between these two, but you should care about a terribly broken patent system that rewards abusive government-backed monopolies on obvious and vague ideas, often even if those ideas are already embodied in common practice. The NTP patents are a perfect example of this -- they cover using a wireless medium to transmit email. Innovative, no? I don't know about you, but I'm sure glad NTP invented that idea, or else no one would have ever figured it out [sarcasm off].
If the USPTO doesn't invalidate these patents, I guess we're (not just RIM -- all of us) looking at 20 years of paying NTP for their email-over-wireless patent(s). Because, guaranteed, if they prevail against RIM, they'll go after everyone else that does anything even vaguely similar, including cell-phone makers/providers, maybe even that wireless hub you have in your home -- ever sent email with that baby?
