Does Imitation Breed Innovation?

According to UCLA legal scholar Kal Raustiala, coauthor of The Knockoff Economy: How Imitation Sparks Innovation, copycats and imitators—legal and illegal—not only fail to hurt creative industries but sometimes help drive them. In a talk at the Goethe Institut Los Angeles, Raustiala explains why a lot of what we think we know about intellectual property is wrong, and how certain industries—like fashion and food—still manage to thrive despite a lack of copyright protection.
