The existence and details of patent laws can matter for creating incentives for invention and innovation. The patent laws in Germany and France in the 1930s reduced the incentives for inventing new drugs.
(p. 141) German chemical patents were often small masterpieces of mumbo jumbo. It was a market necessity. Patents in Germany were issued to protect processes used to make a new chemical, not, as in America, the new chemical itself; German law protected the means, not the end. . . .

(p. 166) Fourneau decided that if the French were going to compete, the nation’s scientists would either have to discover their own new drugs and get them into production before the Germans could or find ways to make French versions of German compounds before the Germans had earned back their research and production costs—in other words, get French versions of new German drugs into the market before the Germans could lower their prices. French patent laws, like those in Germany, did not protect the final product. “I was always against the French law and I thought it was shocking that one could not patent one’s invention,” Fourneau said, “but the law was what it was, and there was no reasons not to use it.”
