I doubt they paid or pay any royalties to anyone for anything.
RCA caught them red-handed, so they caved in - at the time they needed US help in building the industry.
This said, even though the first 1kW at 46.5MHz UKV (FM) station was built in 1946, im earnest they started using it in 50s. They had their own group of engineers who experimengted with it since 1920s.
And when the real FM went into effect, in 1990s, well...patents do not last long.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
