Copyright Symbol (©) in Professional Writing

The copyright symbol © is a specific Unicode character and can appear as part of a copyright notice. U.S. Copyright Office guidance describes traditional notice elements and also explains that U.S. notice requirements changed; symbol usage alone does not create a universal legal conclusion.

Quick answer

Use © when the applicable notice or house style calls for it, but do not assume that adding the symbol alone determines copyright ownership, protection, or legal compliance.

Key details

Core IssueThe © character can be one element of a copyright notice, but legal requirements and effects depend on jurisdiction, date, and context.

Important caveats

Legal Boundary

This is formatting guidance, not legal advice; copyright notice rules and legal effects are jurisdiction- and context-dependent.

Further guidance

Character Difference

Unicode identifies COPYRIGHT SIGN as U+00A9.

Practical Application

Use © only when the applicable notice or house style calls for it, and keep the symbol with the required year/name formatting. Treat the symbol as part of a notice, not as a substitute for determining ownership, licensing, or legal compliance.

Reader Check

Are you following the required notice format without implying that the symbol by itself proves or creates rights?

Use

In U.S. Copyright Office guidance, a copyright notice can include the © symbol together with year and owner information in the relevant context.

Worked Example

A project style might require “© 2026 Example Press.” That is a formatting decision for the notice; questions about ownership or legal effect require the applicable legal/publisher rules.
