AMD was originally licensed access to Intel's 8086 and later designs because customers demanded a 'second source' manufacturer in case Intel had manufacturing problems (sounds familiar!) Intel tried to ditch second sourcing with the 386 but AMD was able to continue manufacturing compatible CPUs. Much later Intel was accused of anti-competitive behaviour by AMD in various markets - which resulted in a fine in Europe and a $1.25bn dollar payment to AMD and patent cross licensing. But - AMD licenses some important technology to Intel eg x86-64.
