Re: Patent 747 amended - Question for the board - cguilfor

Cguilfor, thanks for your summary... I thought as much and I do agree with you, that there will most likely be another Markman Hearing down the road for Patent 747

Here's a copy of the amended Patent 747 for your viewing pleasure. I copied it and reformatted it into a text file ... so, if there are any descrepancies from the original, it's my fault. Please don't hold it against me...thanks.
