Derivative Work – Definition and Explanation

---

Definition

A derivative work is a new creative output that is based on, modified from, or adapted from a pre-existing copyrighted work. It incorporates substantial protected elements of the original while adding new expression, meaning, or style.

Under copyright law, the right to create derivative works is exclusive to the original copyright holder, unless permission is granted or a license (e.g., Creative Commons) allows it. If a derivative contains sufficient original content, it may be independently copyrightable, but that does not override the rights in the original work.

Derivative Work vs. Non-Derivative Work

Derivative works vary across formats and industries but follow a consistent rule: the new version must transform or adapt the original in a creative way.

What Counts as Derivative Work?

The following examples illustrate how different types of original works can be transformed into derivative works under copyright law.

What Does Not Qualify as a Derivative Work?

Simple format conversions like changing a JPEG to a PNG or converting an MP3 to a WAV file do not qualify as derivative works. These are technical processes that do not involve any new creative input or transformation. The content remains identical in structure, composition, and expression, even though the file type has changed.

Cropping or resizing an image or video, without any added artistic interpretation or editorial purpose, generally does not meet the originality threshold required for a derivative work. For example, trimming the borders of a photo to better fit a social media post does not significantly change the creative substance of the original.

Copying and pasting an original work exactly as it is – a paragraph, image, or graphic – without introducing new content, commentary, or style, does not create a derivative work. Even if the content is placed in a new layout or document, the copied material remains the same. The result is a duplicate, not a reinterpretation, and it remains fully subject to the original copyright terms.

Factual lists or structured databases made purely of facts, such as a list of capital cities, weather data, or measurement tables, are not protected under copyright and cannot become derivative works through simple formatting or rearrangement. While the selection or organization of these facts can sometimes be protected if presented creatively, the data itself is not.

These kinds of modifications, while they may be functional or necessary for distribution or presentation, are not considered “original” under copyright law. Derivative works must add new expression, meaning, or interpretation – not just repurpose content in a new format or layout.

Legal Status of Derivative Works

A derivative work is a new creation that builds upon, modifies, or transforms an existing copyrighted work in a meaningful way.

Under Traditional Copyright

Derivative works require advance permission from the copyright holder. Even if an adaptation adds creative value, making it without authorization is considered infringement. Common examples include translating a book, creating a film based on a story, or remixing a song.

These activities may be creative, but they still use protected material in a way that goes beyond fair use. For instance, adapting a novel into a screenplay without a license would be illegal, regardless of how original the script may feel.

Under Creative Commons Licenses

Some Creative Commons (CC) licenses explicitly allow derivative works. Licenses like CC BY, CC BY-SA, and CC BY-NC let users remix, adapt, or build upon the original, as long as they meet attribution or non-commercial requirements.

On the other hand, licenses marked with “ND” (NoDerivatives), such as CC BY-ND or CC BY-NC-ND, prohibit all forms of adaptation. This includes remixes, translations, or modified formats. Using ND-licensed content in a derivative work without separate permission violates both the license and copyright law.

Always review the specific terms of a Creative Commons license before altering or reusing any material.

How Licenses Affect Derivative Works

Understanding Creative Commons license conditions is key to determining what kinds of derivatives are legal.

Key Notes:

• ShareAlike (SA): Requires adaptations to use the same open license. Example: A remix of a CC BY-SA song must also be CC BY-SA.
• NoDerivatives (ND): Prohibits all adaptations, even for personal or educational use.

Fair Use & Derivative Works

Some adaptations may qualify as fair use or fair dealing (in some countries), even without permission. However, this is a legal gray area and depends heavily on context.

Parody uses the original work for humorous or satirical effect and often qualifies as fair use because it adds new meaning. A parody must clearly differ in purpose and tone from the original and not simply copy it for comedic value. Courts often evaluate whether the parody transforms the source and comments on it directly.

Commentary and criticism rely on incorporating parts of the original work to explain, critique, or discuss it. This includes review videos, reaction content, or written analysis. These uses may fall under fair use if the borrowed content is necessary for the commentary and not used excessively.

Educational or research use can allow short excerpts from copyrighted material in classrooms, textbooks, or academic papers. However, this is not automatic; the material must be used in a nonprofit, instructional setting and be appropriate in scale.

Note: Fair use is not a license. It’s a defense in court that must be justified on a case-by-case basis. Legal outcomes are not guaranteed.

How to Legally Make a Derivative Work

To legally create a derivative work, you must follow copyright rules or licensing terms that explicitly allow adaptations.

Step 1: Check the copyright status of the original work
If the work is in the public domain, you can adapt it freely. If it’s released under a Creative Commons license, you must verify which version and type. If it’s “all rights reserved,” you’ll need written permission from the copyright holder before making any changes.

Is it public domain? → Free to adapt.

Is it CC-licensed? → Check the terms.

Is it “all rights reserved”? → You’ll need explicit permission.

Step 2: Review the license
Creative Commons licenses that allow derivatives include CC BY, CC BY-SA, CC BY-NC, and CC0. Licenses that prohibit modification are CC BY-ND and CC BY-NC-ND. Using works under those terms without permission, even with credit, violates copyright law.

Step 3: Comply with conditions
Always credit the original creator. If the license includes a ShareAlike condition, you must license your derivative under the same terms. The adapted work must show original, creative input to qualify as a legal derivative.

This format credits the source, explains the derivative nature, and applies the correct license.

Controversies & Edge Cases

Derivative works often exist in legal gray areas, especially in evolving media formats and digital culture.

AI-Generated Content

When AI systems are trained on copyrighted material, the output may resemble or replicate parts of the original work. This raises legal concerns about whether the generated content qualifies as a derivative.

Courts have not yet reached a consensus, but lawsuits are testing whether AI training practices violate copyright or meet the standard of transformative use. Creators using AI-generated content should proceed with caution, especially in commercial projects.

Fan Art and Fan Fiction

Fan works adapt characters, settings, or stories from copyrighted sources, making them legally derivative. Most creators do not seek permission, and many rights holders allow non-commercial fan creations to circulate without legal action.

However, the tolerance is informal. If fan fiction or fan art is sold or used in branded merchandise, it risks becoming a clear case of infringement. Legal use requires a license or documented permission.

Meme Culture

Memes often remix copyrighted elements—movie stills, song lyrics, or celebrity clips—into humorous or critical commentary. When memes parody or critique the original, they may qualify as fair use.

But their legal protection is limited, especially when used in ads or merchandise. Commercial use of memes requires explicit clearance or could lead to takedown notices and legal risk.
