Yung created a machine that was a remarkable improvement on an existing patented machine, that had been patented by Adam, his brother, approximately years ago. Yung had seen his brother's machine operate for over a decade and each year Yung made improvements on his own version of it in his own shop. Yung's improvements were very creative, not just a simple obvious adjustment, and his version of the machine was twice as efficient as his brother's machine patented 18 years ago. Which one of the following is true?

Question 31 options:

Yung cannot get a patent for his improvement because it is not entirely new or novel

Yung could get a patent for his improvement, and would thereby get a right to make, sell, or use his machine with the original machine incorporated into it

Yung could likely get a patent for his improvement, but has no right to make, sell, or use the original machine.

Adam, the patent holder of the original machine, has the right to make, sell, or use the improvement because its machine is the basis of the improvement

Both Yung's improvement and the original machine lose their patent protection.
