Per U.S. Circ. 38a., Iran is not a participant in the Berne Convention or any other treaty on copyright with the United States.

As such, works published by citizens of Iran in Iran are usually not subject to copyright protection outside of Iran. Hence, such works may be in the public domain in most other countries worldwide.

However

• Works published in Iran by citizens or permanent residents of other countries that are signatories to the Berne Convention or any other treaty on copyright will still be protected in their home country and internationally as well as locally by local copyright law.
• Similarly, works published outside of Iran within 30 days of publication within Iran will also usually be subject to protection in the foreign country of publication. When works are subject to copyright outside of these countries, the term of such copyright protection may exceed the term of copyright inside them.
• Unpublished works from Iran may be fully copyrighted.
• A work from Iran may become copyrighted in the United States under the URAA if Iran enters a copyright treaty or agreement with the United States and the work is still under copyright in Iran.
