In a follow up to an earlier story, the Conan Doyle estate may appeal the ruling against it's copyright claim according to this Publishers Weekly story.
"Is Sherlock Holmes truly a free man? Not so fast say attorneys for the estate of Sir Arthur Conan Doyle.
In a December 23 decision, an Illinois federal court held that Holmes and other characters and story elements in more than 50 Sherlock Holmes stories are in the public domain. But attorneys for the estate of Sir Arthur Conan Doyle this week insisted that the complete characters of Holmes and Watson won’t be freed until the final 10 stories published after 1922 enter the public domain, in 2022."
