New methods of text and image generation using computer software are enormously productive but occupy precarious legal positions. Deriving some or all of their value from existing copyrighted creations, and potentially infringing patents on improvements in computer programming, they can be vulnerable to IP claims. European and North American IP law has been harmonized to a relatively high level of protection that is easy to trigger and difficult to escape once exploitation of an existing knowledge asset is shown. Manifesting judgment and even genius, however, follow-on creators may enjoy defenses to IP claims and limitations on IP exclusivities, while deserving their own IP protection. The harmonization of such defenses is a major theme of this book, and this chapter aims to begin a discussion of them. In the United States, there are defenses to copyright claims grounded in the nature of the subject matter and the exclusion of facts and styles from protection. In addition, there is the fair use exception for commentary, research, and appropriation art, for example. In Europe, there may be quotation or private-study exceptions for researchers' and storytellers' reliance on source materials, incorporation of photographic or painting styles or settings into new images, and the like. The effect of these exceptions or limitations-or their combined effect-may empower Internet users to participate in trans-Atlantic and global cultures involving the generation and sharing of knowledge. Thay can even monetize incremental creation in ideas, products, and works. By turning to the patent system, Internet-connected creators may claim individual rights in faster or more efficient methods of analyzing or generating expressions. Parts of this chapter are based on 'Intelligent Entertainment: Analyzing the Algorithmic Generation and Regulation of Creative Works Across Three Major Themes,' 14 FIU Law Review 179 (2020).
