Which of these is a form of intellectual property that exclude others from using one's invention?

I believe in late 19th century they considered closing the patent office because they thought everything was invented that could be invented.

I've applied for a patent for the wheel. It's still pending.🤔

Good luck getting communist countries to honor or enforce any patent laws of another country.
