The plaintiffs certainly had a larger legal team. We brought our patent attorney and a trial lawyer on our own dime, and we managed to get some time from the chief patent counsel for a very large company because he had a relationship with one of our investors.

The plaintiffs managed to get jurisdiction in their own city (across the country from ours), and the general belief was that the judge granted this because he wanted a change from the drug trials he normally dealt with. This made it very expensive for us, and they definitely had the home court advantage.

I could whine about a lot of other things. For instance the plaintiffs removed every juror candidate who had any college, leaving only locals who I don't think even understood trigonometry. The fact that you're not supposed to be able to patent math, but somehow math on a computer gets through the patent process, etc...

I'm not sure what definition of "obvious" survives then. I was out of college for less than 2 months, and I wrote the code in a single evening. The "infringing" algorithm was less than 10 lines.
