Don't think that is 100% correct, seem to remember Yamaha "prolonged" the
At least they prevented use of "FM" in ICs for computer use after the 95'
Anyways, there is more "protection" when marketing a synth as FM you may
violate a trade mark or something like that.
Bohm got to use the FM method in the 80' due to a tech trade, but where not
allowed to call it FM.
PM was used instead, this is actually more accurate for what Yamaha markets
as FM.
Thin ice, but true FM synthesis may even not be covered by the Yamaha
Innovate a bit on the theme, and may be able to go around the patent.

BTW Maarten, probeer het eens bij een bureau voor rechts hulp.
Als je student bent of een laag inkomen hebt heb je recht op juridiche hulp.
Weet niet of ze je vraag willing behandelen, patent recht is een beetje
buiten hun normale doen.
Het hangt er een beetje om of de jurist die je treft het leuk vind om er
naar te kijken.
Syntens is een andere plek waar ze je mischien kunnen helpen,
(gratis) advies aan techno starters hoort bij hun opdracht.

Well just my thoughs,
