A new wrinkle has emerged: a 'Sherlock Holmes scholar' has filed for a declaratory judgement that all of the Sherlock Holmes writings are in the public domain. But the estate has responded — with hilarious arguments.
If this goes in favour of the Conan Doyle Estate, then it's hard to see how copyright is about expressions and not ideas."
