In general, once a work enters the public domain, copyright protection cannot be restored. However, certain exceptions apply to works of foreign origin.

For eligible foreign works, copyright protection is automatically restored under the
provisions of the Uruguay Round Agreements Act (URAA) and section 104(a) of the copyright law. Previous to the URAA, the North American Free Trade Agreement Implementation Act (NAFTA) contained copyright restoration provisions for certain Canadian and Mexican works.

Under the U.S. copyright law in effect prior to January 1, 1978, copyright could be lost in several situations. The most common were publication without the required notice
of copyright, expiration of the first 28-year term without renewal, or final expiration of the second copyright term.

The U.S. Copyright Renewal Act of 1992 automatically renews first term copyrights secured between January 1, 1964, and December 31, 1977.

The present U.S. Copyright law has changed and enlarged in some cases the
scope of the copyright owner’s rights. The new rights apply to all uses of a work subject to protection by copyright after January 1, 1978, regardless of when the work was created.
