As I understand patents, you wouldn't be able to patent "frequency
modulation", even 100 years ago, but the use of FM for some specific
result, like less noise.
Example from chemistry: mixing of several chemicals is well known, but
the specific recipe for creating some new stuff can be patented.
So here DCT is well known, but it's application to picture compression
may be new.
