Patents are stifling to development, thus all patent protection must be ended completely
Nobody owns inventions, and if one invents something and someone else copies it, this should be appreciated.
Immediate widespread adoption of an invention should be the goal, not limiting implementation using patents so all profit is returned to the patent holder for 20 years.
The more people implementing an idea, the faster it will improve and then again be improved upon, thus leading to entirely new ideas and areas of development.
If a patent holder is concerned about making a profit, then instead of using a patent to stifle development and capture all patent protected profit, simply keep creating better and better products then the competition and sell them. Quality makes profit. If someone copies an invention, their implementation of it might suck. Whoever has the highest quality implementation will sell more.
