The radial on the FW 190 was built on license from Pratt & Whitney.

No.

FW had built Pratt and Whitney engines under license in the earlier
1930s but BMW 139 and the latter BMW 801 used in the FW 190s were BMW's
own designs, not licensed.

Cross licensed were not that uncommon, though. Both sides used things
lisenced from the other and after the war paid the licensed in full.
Allies to Germany, as well as Germany to Britain and US.

Though I'm not sure if Soviets ever paid for their licenses or copies...
