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 …

Generally, clothes are not designed or chosen simply …
