Comment Why patents are bad (Score 5, Insightful) 101
Thinking about this case made me realize why patents are a bad idea. And the problem with patents have to do with the scarcity of invention
Patents give inventors monopoly over their invention, even if other people come up with the same idea independently.
One of the main assumptions justifying this is that invention is scarce. Coming up with an invention requires either a rare original idea which is hard to come by, some special insight that only few brilliant people would have, or a tremendous amount of effort that only few would be willing to spend on developing such an invention.
If inventions are indeed rare, then the benefit of encouraging innovation by giving such monopolistic power to the inventor, and making it safe for the inventor to publish the invention and license it to others is greater than the damage caused by such monopoly. If invention is easy to come by, on the other hand, such monopolistic power stifles innovation rather than foster it.
If you look at most patents, even the better ones, where there is no issue of prior art, most of them are solutions that are easy to come by. They may not be immediately obvious, but if you take any reasonably experienced engineer and give him a few months to work on this problem, they would come up with a solution, and probably a similar solution. With thousands of qualified engineers in each area and hundreds of companies that benefit from such inventions, it no longer makes sense to protect them with patents.
Patentable inventions are supposed to be "non-obvious", but this doesn't solve the problem. Even if the USPTO made a better job of filtering out obvious inventions (more than the lousy job they're doing right now), we'll still have all these patents where the solution is not immediately obvious but are the kind of invention that any qualified engineer could come by. And because this is true for most inventions, and because there is no clear criteria for distinguishing between the true "high quality" and the lower quality patents, I think we are better off by eliminating patents in most areas altogether.
