Can you copyright a fictional character?

Sometimes. The character must be sufficiently delineated — distinctive, consistent and identifiable — rather than a stock type. Visual characters generally qualify more readily than purely literary ones, because their appearance is concrete expression. A character defined only by a broad archetype is not protectable.

How do I prove I created a character first?

With dated evidence of development: sketches, character notes, drafts, and the sequence in which they changed. Timestamping those materials as you go creates records whose dates cannot later be adjusted. Note that this proves the material existed on a date, not that you were the one who conceived it — the two are different things.

Trademark vs Copyright for a Character

Q: Why are some public domain characters still protected?

Because copyright and trademark expire differently. When copyright in the original work runs out, that work enters the public domain. But if the rights holder still uses the character as a trademark on merchandise, that mark continues indefinitely — so using the character in a way that suggests official endorsement can still be a problem.

Key takeaways

Copyright can protect a character, but only one that is sufficiently delineated — a distinctive, consistent, identifiable persona rather than a stock type.
Trademark protects a character used as a brand, typically through merchandising, and lasts indefinitely.
This is why a character can enter the public domain as a copyright work while remaining a live trademark.

The short answer

Copyright protects a well-developed character as part of the creative work. Trademark protects a character that has become a brand.

The two have very different lifespans, and the gap between them is where most of the interesting disputes happen.

When copyright protects a character

Not every character qualifies. Courts have developed tests, and the recurring requirement is that the character must be sufficiently delineated — with consistent, distinctive and identifiable traits — rather than a stock figure.

A grizzled detective with a drinking problem is a type, and types are not protectable; nobody owns the concept. A character with a specific name, appearance, history, relationships, voice and recurring behaviour is an expressive creation, and can be.

Visual characters generally fare better than purely literary ones, because their appearance is concrete expression. A character defined only by a few adjectives in prose is much harder to claim.

Copyright lasts the author's life plus 70 years, or 95 years from publication for works made for hire — and then it ends.

When trademark protects a character

A character becomes a trademark when consumers see it and identify a source: this is that company's character, and merchandise bearing it comes from them.

That protection is tied to goods and services, requires continued use, and lasts indefinitely with renewals. It does not protect the character as a creative work — it protects the character as a badge of origin.

The practical consequence is the interesting part. When a character's early copyright expires, the underlying work enters the public domain and can be reused. But if the rights holder still uses the character as a trademark on merchandise, that mark survives, and using the character in a way that suggests an official connection can still be actionable.

What this means for a creator

If you are building a character you intend to be commercially significant:

Develop it concretely. Distinctiveness is the legal test and the artistic goal at the same time. Names, visual design, consistent traits and history all help.
Register the copyright in the works where the character appears.
Consider trademark registration if the character will appear on merchandise or as a brand element — but only once you are actually using it that way.
Keep dated development records. Character disputes are usually priority disputes.

Where a timestamp fits

Character claims are frequently about who created it first, and they often arise years later, in a context — a pitch, a collaboration, a submission to a studio — where the material was shared privately.

Timestamping character bibles, early sketches, design sheets and drafts creates a dated record of the character's development that does not depend on anybody's archive being intact or honest. Where a character evolves over months, a sequence of timestamps tells a story of creation, which is considerably more persuasive than a single dated file.

It proves the material existed on those dates, not that you authored it. See proof of existence vs proof of authorship.
