Where do I send Mr Mozart's royalities? or even Ormandy's? Or Elvis's? or Sid Vicious's

You were talking the difference between 17 and 75 years.

I'll give you a personal example. I invented and patented a glove coating process. Although we made a successful product out of it, it may not be used to its potential for another ten years.

That's one.

I wrote a book. It's taken me two years just to get some academic buy-in. It may be seventy-five years before it reaches its market potential.

Got it?

I wrote a book. ... It may be seventy-five years before it reaches its market potential.

I just wrote a book called "How to Survive When the Sun goes Supernova." It won't reach market potential for another 120 million years. Should copyright protect my future earnings until it does? I expect it to be a really hot seller.
