Mickey Mouse in Dilbert Comic - RF CafeYou might have seen in the news about the copyright expiration of Disney's original version of Mickey Mouse, as seen in Steamboat Willie and Plane Crazy. Per the U.S. Patent and Trademark Office (USPTO), as a general rule current copyright law for works created after January 1, 1978, copyright protection lasts for the life of the author plus an additional 70 years. All my (and your) original publically "published" RF Cafe material, regardless of whether officially registered with the USPTO, is covered by copyright law. Archive.org is a valuable source of proof of first instance. Usage exceptions per "fair use" law is allowed. As is the case for most legal matters, many special cases, exceptions, and allowances are provided to help keep lawyers employed. Works published prior to 1978 are protected for 95 years. 2023 - 95 = 1928, so anything published on or before 1928 is no longer copyrighted. That includes the original rendition of Mickey Mouse. (Walt Disney died in 1966, BTW) Dilbert comic strip creator Scott Adams exploited the situation with the strip shown above. Ironically, that comic strip depicting the now public domain Mickey Mouse will be protected by copyright for 70 year beyond the lifetime of Scott Adams (who, to the disappointment of Wokesters, still lives). If I so desire, I can now incorporate Mickey Mouse into the RF Cafe logo, but I won't.

Check out the Public Domain Day pages on the Duke Law School website for some good info.
