Is there a magic percentage that lets you modify someone else’s copyrighted work and safely call it your own? No—and that “twenty percent rule” you may have heard online is one of the most persistent copyright myths. In this episode, we break down what actually matters when you use, imitate, edit, remix, or rebuild someone else’s creative work. Whether you are dealing with photos, videos, music, illustrations, paintings, blog content, or AI-assisted edits, the key question is not simply how much changed. Copyright analysis looks more closely at the original expression, what was copied, how the new work was created, and whether an exception such as fair use may apply. We start with the distinction between an idea and its expression. Copyright does not generally give someone ownership over an abstract idea. Two people can independently take similar tourist photos at the Eiffel Tower. The idea of posing in front of a famous landmark is not owned by the first person who did it. But if you take someone else’s photograph, upload it into an AI tool, replace the person, change the background, adjust the clothing, and publish the result, you are starting from a different place. You are modifying someone else’s underlying creative work. That distinction matters because modern tools make copying and modification incredibly easy. Easy, however, is not the same thing as legally safe. We also discuss substantial similarity. Courts do not use a universal percentage test to decide whether two works are too similar. There is no legal meter that flashes green at twenty-one percent different. Instead, the analysis can focus on protectable expression and the nature of the similarities between the works. The uniqueness of the original work can matter too. Some ideas have only a limited number of ordinary ways to express them. Other creative works are highly distinctive. The more recognizable the protected expression you borrow, the harder it may be to argue that you merely used the same general concept. Then we tackle fair use. Fair use is real, but it is not a magic phrase. Calling a use “educational,” putting it in a blog, presenting it publicly, or saying it is a parody does not automatically make the use lawful. Fair use is a fact-specific analysis. For founders and small business owners, the practical takeaway is straightforward: when possible, create independently. Take your own photo. Build your own graphic. Record your own video. Develop your own campaign. If you need someone else’s work, consider permission or a license. We also cover images found online, AI-assisted edits, music, competitor-inspired campaigns, and the mistaken assumption that educational use automatically means fair use. The episode also explains why attribution is not the same thing as permission. Giving credit may be polite or required by a license, but credit alone does not give you rights you did not otherwise have. The bigger business lesson is that copyright strategy should not begin with, “How much can we copy before we get in trouble?” A better question is, “How can we create something that is genuinely ours?” Original work can strengthen your brand, create assets your company may own, and reduce the chance that an important campaign has to be pulled or rebuilt after launch. If copyrighted material is central to a product launch, ad campaign, website, video, software product, or other meaningful commercial project, getting clarity before publication is often easier than cleaning up a dispute afterward. This episode is general educational information, not legal advice. Copyright questions can turn on specific facts and uses. If you have ever heard “just change twenty percent,” this episode is your reminder that copyright law did not come with a percentage slider.
