Copyright symbol usage. When and how to use ©.
The copyright notice - © followed by year and owner - was required for protection in the US until 1989. Since the US joined the Berne Convention, notice is no longer required for protection. But using it remains valuable: it puts the world on notice, prevents an "innocent infringement" defense, and signals ownership professionally.
Start here.
Since 1989, US copyright protection exists without notice. The symbol is optional.
Notice prevents "innocent infringement" defense and signals ownership.
© [Year] [Owner Name]. Example: © 2026 File.Business, LLC.
Use year of first publication. For works regularly updated, the current year is also acceptable.
Name of the copyright holder. Often a company name, sometimes an individual.

Format options
Standard: © [Year] [Owner Name]. Also acceptable: "Copyright [Year] [Owner Name]" or "Copr. [Year] [Owner Name]". The ASCII symbol "(C)" is widely understood but technically not the legal equivalent.
Placement
Where viewable. Websites: footer. Books: copyright page. Photographs: backside or metadata. Software: about screen or license agreement.
Year
Year of first publication. Some use current year for continuously updated works (e.g., websites). Range acceptable: © 2020-2026 File.Business.
Owner
The actual copyright holder. For company-owned works: company name. For individual authors: individual name. For works for hire: the hiring party.
Why use it if not required
(1) Notice prevents innocent infringement defense in litigation. (2) Signals professional ownership. (3) Educates users about copyright. (4) Establishes claim publicly.
Multiple authors or works
For collective works: notice for the collective ("© 2026 File.Business") covers contributions made for hire. Individual contributors who retained rights may include their own notice.
Sound recordings
Use ℗ (the phonorecord symbol) for sound recordings, not ©. Format: ℗ [Year] [Owner].
Internationally
© is recognized worldwide under the Berne Convention.
