Bottom line is that x86 is a complete ISA, where x86-64 is an extension of an ISA.
You can make x86 CPUs without x86-64, but you can't make x86-64 CPUs without x86.
If push comes to shove, Intel can simply disable the 64-bit mode on their CPUs and continue business as usual. Since most people are still stuck in 32-bit land anyway, it's not going to make much of a difference. Then Intel can just develop an alternative 64-bit implementation, or promote their Itanium, or just buy the rights to AMD's x86-64.
AMD will have to stop producing CPUs altogether. And AMD is not large enough to make a different CPU architecture a success.
Which means that Intel whole Xeon line will be rendered useless without the 64bit implementation.
It might not even be a case of winning or losing. The bad publicity for AMD and the costs of the lawsuit alone might be enough to kill off AMD before the case even comes to a decision.
Aside from that, you already know that I don't agree that Intel can't stop AMD from selling x86 chips. We went over that, I provided historic evidence.
It is a cross license agreement, if Intel wants to stop AMD from shipping x86 CPUs without a court declaring that AMD has breached the agreement, Intel needs to stop shipping CPUs with 64bit extension as well.
