From an OTL Tube amplifier manufacturer. Is it that OTL's seems are now a dying breed, and it's just another income stream?
What do you make of this patent on this Class-D amplifier??

That is known as an FM amplifier. Standard half bridge switch for the output stage. Similar to Yamaha Electronics design back in the 90's.
Obviously the US have lower levels of rules.
One cannot patent a process, one can only patent a noval idea.

Thanks Jon.
There are 4 pages to this, if you click on the "sections" on the left side.
If it's been done before 30 years ago, is it possible to get a patent applied on it because it's been used here as a Class-D audio amp instead of whatever back then?
Is there any advantage to todays Class-D's? As he has 16 claims for the better with it.
Apparently he also uses GaN fet output devices.

Patents and law can be a minefield.
A patent might be found to be invalid or irrelevant if someone tries to assert it against a large company (with many good lawyers). How the actual claims are written is critical to survival and/or enforceability of a patent. There a lot of ways, in which a patent may not guarantee IP protection or may not be enforcceable.
