Methods of Approaching a Copyright Investigation

There are several ways to investigate whether a work is under copyright protection and, if so, the facts of the copyright. These are the main ones:


  1. Examine a copy of the work for such elements as a copyright notice, place and date of publication, author and publisher. If the work is a sound recording, examine the disk, tape cartridge, or cassette in which the recorded sound is fixed, or the album cover, sleeve, or container in which the recording is sold;

  2. Make a search of the Copyright Office catalogs and other records; or

  3. Have the Copyright Office make a search for you.

A Few Words ofwebsite, write the Copyright Office, or call (202) 707-3000.

If you wish to do your own searching in the Copyright Office files open to the public, you will be given assistance in locating the records you need and in learning procedures for searching. If the Copyright Office staff actually makes the search for you, a search fee must be charged. The search will not be done while you wait.

In addition, Copyright Office records in machine-readable form cataloged from January 1, 1978, to the present, including registration and renewal information and recorded documents, are available for searching from the Copyright Office website at www.copyright.gov.

The Copyright Office does not offer search assistance to users on the Internet.

    Impact title 17 of the United States Code). Most provisions of this statute came into force on January 1, 1978, superseding the copyright act of 1909. These provisions made significant changes in the copyright law. Further important changes resulted from the Berne Convention Implementation Act of 1988, which took effect March 1, 1989; the Copyright Renewal Act of 1992 (P.L. 102-307) enacted June 26, 1992, which amended the renewal provisions of the copyright law; and the Sonny Bono Copyright Term Extension Act of 1998 (P.L. 105-298) enacted October 27, 1998, which extended the term of copyrights for an additional 20 years.

    Works Circular 15a.

    Works ad interim copyright.)

    Accidental Omission � The 1909 statute preserved copyright protection if the notice was omitted by accident or mistake from a �particular copy or copies.�

    Unauthorized Publication � A valid copyright was not secured if someone deleted the notice and/or published the work without authorization from the copyright owner.

    Sound Recordings � Reproductions of sound recordings usually contain two different types of creative works: the underlying musical, dramatic, or literary work that is being performed or read and the fixation of the actual sounds embodying the performance or reading. For protection of the underlying musical or literary work embodied in a recording, it is not necessary that a copyright notice covering this material appear on the phonograph records or tapes on which the recording is reproduced. As noted above, a special notice is required for protection of the recording of a series of musical, spoken, or other sounds that were fixed on or after February 15, 1972. Sound recordings fixed before February 15, 1972, are not eligible for federal copyright protection. The Sound Recording Act of 1971, the present copyright law, and the Berne Convention Implementation Act of 1988 cannot be applied or be construed to provide any retroactive protection for sound recordings fixed before February 15, 1972. Such works, however, may be protected by various state laws or doctrines of common law.

    The Circular 15a.

    In evaluating the meaning of the date in a notice, you should keep the following points in mind:

    Works Published and Copyrighted Before January 1, 1978 � A work published before January 1, 1978, and copyrighted within the past 75 years may still be protected by copyright in the United States if a valid renewal registration was made during the 28th year of the first term of the copyright. If renewed by registration or under the Copyright Renewal Act of 1992 and if still valid under the other provisions of the law, the copyright will expire 95 years from the end of the year in which it was first secured.

    Therefore, the U.S. copyright in any work published or copyrighted prior to January 1, 1923, has expired by operation of law, and the work has permanently fallen into the public domain in the United States. For example, on January 1, 1997, copyrights in works first published or copyrighted before January 1, 1922, have expired; on January 1, 1998, copyrights in works first published or copyrighted before January 1, 1923, have expired. Unless the copyright law is changed again, no works under protection on January 1, 1999, will fall into the public domain in the United States until January 1, 2019.

    Works First Published or Copyrighted Between January 1, 1923, and December 31, 1949, But Not Renewed � If a work was first published or copyrighted between January 1, 1923, and December 31, 1949, it is important to determine whether the copyright was renewed during the last (28th) year of the first term of the copyright. This can be done by searching the Copyright Office records or catalogs as explained previously. If no renewal registration was made, copyright protection expired permanently at the end of the 28th year of the year date it was first secured.

    Works First Published or Copyrighted Between January 1, 1923, and December 31, 1949, and Registered for Renewal � When a valid renewal registration was made and copyright in the work was in its second term on December 31, 1977, the renewal copyright term was extended under the latest act to 67 years. In these cases, copyright will last for a total of 95 years from the end of the year in which copyright was originally secured. Example: Copyright in a work first published in 1925 and renewed in 1953 will expire on December 31, 2020.

    Works First Published or Copyrighted Between January 1, 1923, and December 31, 1949, and Registered for Renewal � When a valid renewal registration was made and copyright in the work was in its second term on December 31, 1977, the renewal copyright term was extended under the latest act to 67 years. In these cases, copyright will last for a total of 95 years from the end of the year in which copyright was originally secured. Example: Copyright in a work first published in 1925 and renewed in 1953 will expire on December 31, 2020.

    Works First Published or Copyrighted Between January 1, 1964, and December 31, 1977 � If a work was in its first 28- year term of copyright protection on June 26, 1992, renewal registration is now optional. The term of copyright for works published or copyrighted during this time period has been extended to 95 years by the Copyright Renewal Act of 1992 and the Sonny Bono Term Extension Act of 1998. There is no need to make the renewal filing to extend the original 28- year copyright term to the full 95 years.

    However, there are several advantages to making a renewal registration during the 28th year of the original term of copyright. If renewal registration is made during the 28th year of the original term of copyright, the renewal copyright vests in the name of the renewal claimant on the effective date of the renewal registration; the renewal certificate constitutes prima facie evidence as to the validity of the copyright during the renewed and extended term and of the facts stated in the certificate; and, the right to use the derivative work in the extended term may be affected. Request Circular 15 for further information.

    Unpublished, Unregistered Works � Before 1978, if a work had been neither �published� in the legal sense nor registered in the Copyright Office, it was subject to perpetual protection under the common law. On January 1, 1978, all works of this kind, subject to protection by copyright, were automatically brought under the federal copyright statute. The duration of copyright for these works can vary, but none of them expired before December 31, 2002.
