I've actually seen this play out before. The next move for a Quest, etc is to try to change the venue out of California. I watched a similar "patent company" sue everyone in Chicago and win and then they got a company with deep $$$ and got tied up in change of venue to NYC and years in attorneys fees to end up losing and having everything invalidated. My gut tells me this is too much too soon. IMO
That is one possibility. But, the most obvious is that there are valid claims on patent infringment as well as business opportunities going forward that would make partnerships worthwhile. Each scenario has merit. I'll stick with the later until more information is available.
