VIA rights did not come from Cyrix.

Cyrix famously had to skirt IP laws by using TI and IBM foundries because those two companies had full Intel 3rd party licenses. Cyrix was sued and paid big bucks settlement just to be able to use Intels patent 338 (long expired). Later cross licensing had little to do with Cyrix, and more with National owning crapload of patents they could use to retaliate against Intel - that 1998 deal https://www.intel.com/pressroom/archive/releases/1998/CN0203... resulted in full cross licensing allowing National build straight 1:1 copies of Intel chips if they desired.

When VIA bought Cyrix from National they didnt inherit ANY of those licenses. VIA was sued just as original Cyrix and National did, and once again had to pay big bucks to settle despite just aquiring Centaur with a bunch of patents and Intel license https://www.pinsentmasons.com/out-law/news/intel-and-via-set...
