- Intellectual property law, or IP law, is based on certain assumptions about creative behaviour. The case for regulation assumes that creators have a fundamental legal right to prevent copying, and without this right they will under-invest in new work. But this premise fails to fully capture the reality of creative production. It ignores the range of powerful non-economic motivations that compel creativity, and it overlooks the capacity of creative industries for self-governance and innovative social and market responses to appropriation. This book reveals the on-the-ground practices of a range of creators and innovators. In doing so, it challenges intellectual property orthodoxy by showing that incentives for creative production often exist in the absence of, or in disregard for, formal legal protections.
