Hm, the patent you mention refers to Itanium in several places. I doubt that Pentium through Prescott mechanisms meet its complexity.
Look at patent #5,732,207, it is the one I was talking about in my previous post. Filing date (February 28, 1995)coincides roughly with the production of first Pentium CPUs.
What is even more interesting is that one of the inventors was Patrick Gelsinger.
