The United States Supreme Court, in Unicolors, Inc. v. H&M Hennes & Mauritz, L.P., a recent 6-3 decision, found that innocent legal errors in copyright applications do not preclude copyright holders from taking advantage of the safe harbor provision of the Copyright Act, which protects registrants from having their copyrights invalidated due to inadvertent errors.  The Court’s ruling therefore made clear that such errors in copyright applications—including both mistakes of law and mistakes of fact—will rarely be the basis for invalidation.
