Intel x86 and patent implications
Why isn't anyone interested in licensing the Ford T? That was a great car!

Well it was. And at the time the x86 probably was a good processor too (though we had to suffer from its 64 kB segment limit for several computer generations). But for high end it has been surpassed by several generations of Pentium, and for embedded we've seen the advance of ARM, which is a lot cheaper and consumes much less power.
