"that CM should try to avoid in his 2008 re-exam testimony. It doesn't mean those areas were fatal to the patent. It is obvious that ACER should not be allowed to pressure CM on those same points. Therefore, they are not going to let Acer's attorney get away with it. The more Acer's attorney's want to use the letters, the more TPL will put up a fight.

It is more a matter of what is right is right and they will not let Acer have even a small victory, especially if they can easily avoid it.."

I hope you are correct. I think it is more than that based on the tone of the response..and the multiple responses and supporting documentation. Once you lose the privilege those documents will be produced over and over again..and used over and over again possibly to our disadvantage. If you don't think your being hurt..why punch back so hard.
