When businesses commission a logo, they usually want two things. Something that looks great and something they fully own. Where many brands run into trouble is misunderstanding how copyright and trademark law actually work, especially when it comes to derivative works.
One of the most common myths we hear is that changing an existing logo by a certain percentage makes it original. That idea is not just incorrect, it is risky.
Let’s break this down in plain language.
What Is a Derivative Work?
A derivative work is a design that is based on an existing copyrighted work. This includes edits, redraws, modifications, and adaptations of something that already exists.
In simple terms, if a new logo is clearly built from another logo, it is likely considered derivative.
Copyright law gives the original creator exclusive rights to their work. That includes the right to decide who can modify it or create new versions from it. Without permission, those changes do not create ownership.
How This Applies to Logo Design
Logos are protected by both copyright law and trademark law.
In logo design, a derivative work can include:
-
Redrawing an existing logo in a different style
-
Changing colors, fonts, or proportions of another brand’s logo
-
Starting with a competitor’s logo and adjusting it
-
Using AI or stock logos that closely resemble existing brands
If the core visual idea is still recognizable, the logo is not truly original.
Trademark law goes even further. If a logo could confuse customers or make them think two businesses are related, that alone can be grounds for a legal dispute.
The Truth About the “25 Percent Rule”
There is no rule in copyright or trademark law that says changing a design by 10 percent, 25 percent, or any other amount makes it yours.
Courts do not use percentages to decide infringement. Instead, they ask one key question:
Would an average person recognize the original work in the new design?
If the answer is yes, the logo is likely considered derivative, regardless of how many changes were made.
The “25 percent rule” is a myth that has been repeated for years, but it has no legal foundation.
Inspiration Is Allowed. Copying Is Not.
Good designers study trends and take inspiration from the world around them. That is normal and healthy for creative work.
The difference comes down to process.
Safe inspiration looks like:
-
Exploring design styles rather than specific logos
-
Pulling ideas from many sources instead of one
-
Starting with concepts and sketches from scratch
Risky copying looks like:
-
Editing or redrawing an existing logo
-
Keeping the same shapes, layout, or visual structure
-
Relying on one clear reference and building from it
If two logos can be easily compared and seen as related, that is a warning sign.
Why This Matters for Your Business
Using a derivative logo can create serious problems later, including:
-
Cease and desist letters
-
Forced rebranding
-
Trademark disputes
-
Loss of customer trust
-
Marketing and packaging that must be scrapped
Even worse, a logo that is not truly original may be impossible to trademark or defend if another company challenges it.
A logo should be an asset, not a liability.
The Bottom Line
- Changing an existing logo does not make it original.
- There is no percentage rule.
- Recognition matters more than modification.
- Original logo design protects your brand long term.
