When creators and innovators take up a new task, they face a world of existing creative works, inventions, and ideas, some of which are governed by intellectual property (IP) rights. This presents a choice: Should the creator pay to license those rights? Or, alternatively, should the creator undertake to innovate around them? Our Article formulates this “build on/build around decision” as the fundamental feature of sequential creativity, and it maps a number of factors—some legal, some contextual—that affect how creators are likely to decide between building on existing IP or building around it. Importantly, creators are influenced by more than just formal IP rights. We identify three other sets of factors—(1) Technological and Artistic, (2) Market, and (3) Creator—that can also affect the path of sequential innovation by encouraging either building on or building around. Our focus on creators’ build on/build around decisions offers a richer, but more complex, account of the nature of sequential innovation and, in so doing, yields insights into its efficient legal regulation.
