Origami Copyright

An origami figure is a creative expression, which is a form of intellectual property that is protected by copyright law in the U.S. and abroad. All rights in a copyrighted work belongs to the composer of the figure. In origami, the folded figure, photographs and other images of the folded work, and printed or electronic instructions for folding the work, are all protected by copyright.

Under copyright law, origami instructions are treated much like a musical composition or a piece of software. Personal use is permitted, but any commercial use or republication requires the express permission of the composer. With respect to instructions, both the composer of the origami figure as well as the diagrammer (if different) possess rights. In addition, the original composer retains rights in derivative works, i.e., modifications of the design. In both law and practice, one must obtain permission from both the composer and the diagrammer before republication or other commercial usage is allowed.

Questions About Origami Usage

  • Q. Can I use an image of an origami figure commercially?
    A. Only after securing permission from the composer of the figure (and if different, the photographer who took the image).
  • Q. I found some folding instructions in a book/on the web. May I use figures I folded myself from these instructions commercially?
    A. If the figure is explicitly noted as a traditional figure, yes. If the figure was composed by an individual (who is usually credited in the book), you may fold it for personal use but commercial usage of the origami figure requires permission from the composer of the figure.
  • Q. I learned an origami figure from a published source. May I teach it to someone else?
    A. Most copyright law contains certain exceptions, which in the U.S. come under the doctrine of “Fair Use.” Although the law is (intentionally) somewhat vague about the specific boundaries of “Fair Use,” teaching an origami figure to someone else informally is generally considered acceptable.
  • Q. May I teach an origami figure to someone else for hire?
    A. That would be considered commercial usage for which permission must be obtained from the composer.
  • Q. What if I “reverse-engineer” an origami design? Can I republish my own version?
    A. No. a reproduction of a creative work is considered a derivative work no matter how it was derived and the original composer retains rights in the work.
  • Q. What if I modify an origami design? Can I republish my own version?
    A. No. a modification of a creative work is considered a derivative work and the original composer retains rights in the work.
  • Q. I composed my own origami design and then subsequently found a published model that’s very similar. Can I publish my design?
    A. There are several documented examples of simultaneous composition in origami, particularly among figures of a highly geometrical nature. (This situation is analogous to two musical composers independently composing the same melody; it’s rare, but does happen.) If the figures were composed independently, each composer has the right to assign rights to his/her own design.
  • Q. Can I copy your crease patterns, change the colors, rename them, claim that they're "traditional" and then try to pass them off to collectors as my own work?
    A. No.
  • Q. Can I consider these questions and answers to be legal advice?
    A. No. You may find them useful for understanding general issues, but for any specific legal question you should contact your own lawyer familiar with the relevant laws in your area.
