Oh that's just absurd. What are they going to do?
I should have added a :) smiley, because this was intended to be
absurd or to show, how absurd software patents can get. Everyone I
guess knows that Amazon patented the "On-Click" method. I wanted to
say that those things exist in music software, too. Maybe FM synthesis
is not a good example, because this technique is actually more complex
than Amazon's.
Sue John Chowning who claims to have invented FM audio
synthesis
way back in the 70s?
I now did a bit more research on that and I was a bit wrong: The
patent is Standford's and Yamaha is a licensee. Also this patent seems
to have expired 1995. But not without achieving this:
"Stanford's FM synthesis patent, which expired two years ago, was the
second biggest money maker in campus history. It brought in more than
$20 million."

I think, several Waveguide patents also developed at Stanford are
still valid. Also the documentation of Perry Cooks STK says:
"The basic Chowning/Stanford FM patent expired in 1995, but there
exist follow-on patents, mostly assigned to Yamaha. If you are of the
type who should worry about this (making money) worry away."
Sue every radio station in the world?
I think, the patent only covered the use of FM in a musical
instrument.
