The problem with ending patents is the alternative is medieval guilds that jealously guard their knowledge, sometimes using lethal force. The great thing about patents is that they force people to publish the knowledge so it won't be lost to the sands of time when they close up shop. That said, our current patent system is problematic for sure. The bar for getting a patent has become far too low as systems have becom…
The great thing about patents is that they force people to publish the knowledge so it won't be lost to the sands of time when they close up shop. That's a benefit that depends on the difficulty of reverse engineering the knowledge from working samples. As analytical instruments and procedures have improved, the relative disclosure benefit of patents has diminished. Worse, patents are increasingly written to hide the…
Lots of companies tried to copy the process (without licensing the patent). They couldn't, because the patent didn't describe all the know-how needed to make the process work. Companies that licensed the patent got the benefit of an on-site engineer that would help them get their process working. So most "plate" glass was thereafter float glass, made by paying licensees.
That is: the invention was really protected not by patents, but by trade secrets. And unlike with the mediaeval guilds, nobody had to be assassinated.
So it seems to me that in addition to being harmful, patents really are unnecessary; as long as there is also know-how. If there is no know-how, then I don't think the patent should be issued. Therefore, there is no need for patents.
