This is my point he is limited to his area of expertise therefore cannot be really challeged on this point. Yes the code has been changed since he was involved in it. That is not the issue here. What is more important is the fact that the patents need to be understood from a higher level. This is why Google is trying to "dumb" it down to code which will waste a lot of time and energy and then it has to be analyzed from a patent perspective. So in months they can determine the code was changed and then in December they show all this to the judge and he says he is not qualified and needs independent analysis which wastes more time. This is Google's strategy .. delay, delay and delay, spend whatever it takes. In the end if the judge determines that they are still infringing and slaps them with a punative royalty > 7% they simply write a cheque, make a deal and move on. They do this because they can not because they are necessarily convinced they are right. It's just Larry Page's way as Ellison said last week when he described how they don't think they are infringing on java when they write the Android code. He says that is evil.
