Lots of patent hate in the first few comments. If we take the position that an inventor should be able to try and get profit from their invention how can we protect that without patent system?
I also view the goal of the patent system as benefiting a society by encouraging the people to innovate. While somewhat similar to the current goals (rewarding the inventors) it is subtly different because its success and failure is determined not by the fairness to each inventor but by its statistical impact on innovation. If it tends to encourage innovation, even if in a few corner cases the time limits are too short for the inventor to reap the full reward, so be it. If it tends to stifle innovation by focusing on fully defending every inventor it needs to be repealed. My 2c.
