AMD didn't patent the x86-64 instruction set, but there are x86-related patents. x86 patents are not on the instruction set, which may be copyrighted for the specific mnemonics and names used for various features, but for implementation techniques. Unfortunately, patents are often overly broad or obvious, so even a clean reverse engineering attempt may fall afoul of many circuit implementation or even software emulation technique patents.

Transmeta was the last successful non-licensee to battle Intel over x86 patents because Transmeta had built up a powerful defensive patent portfolio.
