I think that applies to newer versions, not the older ones. Given that
ARM goes back to the 1980s, any patents from the earliest years would

It has nothing to do with patents.
 
The architecture license provides far more than the ability to implement
the arm instruction set.   BTDT.

IANAL, but there are four kinds of “intellectual property”: copyrights,
patents, trademarks and trade secrets.

If you were incorporating logic components developed by ARM, then
licensing those might be covered by copyrights and trade secrets.

But if you’re a company like Apple, which designs and builds its own
chips, then they need neither of those things.
