Innovation comes only from creativity and skills - you not only need the idea, but also the knowledge to make this idea
reality. Also I strongly doubt that 1952 was the most innovative year in the USA.
Most patent systems in the world have not yet been updated properly for innovations like Internet and genetic technology,
thats the main problem we face today. Also most innovation cycles are already faster as the time it takes from application
until a patent was granted.
I think, a stronger limit for patents is a good idea in general. You really need to do something special to get the right to
protect your ideas from rivals for some time. Patents in general are something countering innovation. They only get a force
for innovation, when you need to be really creative to get one. As a reward for innovation - not as measure against other
companies and countries.
