amok: No, the patent system isn’t just about public disclosure. It also exists to give inventors a temporary period of exclusive rights, that’s why patents are time-limited
mqstout: I see you're in denial and wrong. Typical. How about you look up the actual history, origin -- and even recent (though not current*) application -- of patents? The exclusivity is the "payment" for the disclosure.
I think you did not notice the words "isn't just". I’m not denying that patent law is important for the spread and growth of knowledge, it is a cornerstone. But laws can have more than one purpose or goal in mind. The earliest formal patent law we know, the Venice Patent Statute of 1474, did emphasize public disclosure, but that focus have broadened over time. The English Statute of Monopolies of 1624, for example, tied patents to innovation and economic development, and later, the U.S. Constitution (1787) and the Patent Act of 1790 explicitly connected disclosure with a grant of exclusive rights. That meant inventors not only had to share their knowledge but also received a limited-time economic reward or protection. So, the emphasis in patent laws has almost always been a balance between disclosure and economic incentive and protection.
mqstout: As for your assertion that progress would halt without patents: No. We've seen otherwise. Don't be such a cynic against society.
In a capitalist system? A couple of examples come to mind. The Dutch in the 17th century had very weak patent laws, and much of their innovation was controlled by guilds. They became famous more for reverse engineering and improving existing ideas rather than for original invention. Switzerland is another one, they had no patent laws until the 1880s, yet built industries (like chemicals and pharmaceuticals) largely by copying inventions from Germany and elsewhere.
History shows that when governments operate without patent laws, companies tend to rely on trade secrets and being first to market. These systems often see widespread copying and imitation. But once such economies expand beyond a local market and begin trading internationally, they face pressure to adopt patent laws to align with trading partners. That’s why today, as far as I know, every country has some form of patent law.
What example did you have in mind?
