There is a complex cross licensing agreement between AMD and Intel which was updated in 2015, but to my knowledge, no official licensing has been extended outside these two by either except for a few Chinese tech transfer deals. In the past, Intel has consistently tried to put anti-competitive legal or financial roadblocks in the way of third party implementers as well as contracted licensees like AMD including rebates for vendors who didn't use competing products, invoking patents on other necessary parts of implementation like memory controllers, crippling compiler generated code for competitor CPUs etc.

Today, there don't seem to be as many roadblocks or technical advantages for Intel for x86 compatible clones although Intel fired off a warning shot regarding Microsoft's emulation of x86 for Windows on ARM; perhaps the rest of the industry is still reeling from having had to deal with Intel and would prefer to implement ARM CPUs to avoid that history.
