From Mises Wire:
Intellectual Property: Innovation Should Serve Consumers, Not Producers
Proponents of intellectual property rights often rely on one of two lines of reasoning. The first is based on the misunderstanding that the frequency or volume of innovations determine economic growth. The second is captured by the question, “So if I spend $1 billion on R&D (research and development) to bring a new drug to market, anyone should be able to copy my drug without compensation?” Both are based on the same fundamental error: assuming that innovation is a matter of production. It is not. Innovation is all about entrepreneurship, and that’s why intellectual property rights do not and cannot help.
