The smooth way would obviously be to invalidate all patents exactly 20 years from now. That's how long patents last. You don't take away anything from anyone. The only drawback is that it will take 20 years to implement. However, it will already have an effect much sooner - why filing for a patent in 2030 when it expires already in 2034?
