2124.2 Effect of the Manufacturing Clause on Copyright Term
If such works did not comply fully with the manufacturing clause at the time of first publication, copyright was lost upon publication unless, in the case of an English language nondramatic literary work (including periodicals), ad interim copyright was secured. For such works, if ad interim copyright was secured and a U.S. edition was published and registered before ad interim copyright expired, copyright was extended to the full original term of twenty-eight years. If a U.S. edition was not published before ad interim copyright expired, copyright was lost at the expiration of ad interim copyright. In such cases renewal registration is not possible.
Exception: If a work was manufactured and published in the United States with the statutory copyright notice prior to the expiration of ad interim copyright, but the U.S. edition was not registered for the original term before ad interim copyright expired, renewal registration may be possible for both editions.
