I just wrote a blog post on RIMarkable where I ask a question about if NTP and RIM were to settle in light of an injunction that looks more and more likely and will paraphrase and ask it again here.
If they do settle but the U.S. patents office eventually upholds their finding that all of NTP's patents are invalid, is RIM just out of the dough that they have to cough up to keep operating now?
