This is a common misconception about patents.

They were never intended to reward innovation. They do intentionally grant fixed-duration monopolies.

Patents were intended to encourage companies to disclose trade secrets, forwarding public knowledge. In return, that company is granted continued exclusive use of the idea, as if it had never been revealed. This is also why ALL patent drawing are in the public domain.

If patents were only intended to encourage the disclosure of trade secrets, then they would only cover things that you actually can keep secret. Many if not most of the patents cover features of products that become obvious when the product is released. You cannot keep a trade secret on your innovative mouse trap design and then go ahead sell the mouse trap.
