In the United States, the only Sherlock Holmes remaining in copyright is The Case Book, which will enter the public domain between 2016 and 2023. A legal challenge that would have invalidated a 1998 extension to the length of copyright -- putting Sherlock Holmes into the public domain immediately -- was thrown out by the Supreme Court January 15, 2003.

The American copyrights are owned by the Estate of Dame Jean Conan Doyle. The American agent for administering them, and related rights in the Sherlock Holmes character, is Jon Lellenberg (Hazelbaker & Lellenberg, 211 East Delaware Place suite 605, Chicago, Illinois 60611), JonLellenberg@aol.com.
