The United States Patent & Trademark Office Database has a Service Mark application filed last week by Bethesda Softworks for "Fallout," with the following explanation: "Entertainment services in the nature of an on-going television program set in a post-nuclear apocalyptic world." This may explain the recent tease by the voice actor who plays Three Dog saying "There may be more of the Dog coming!" Or it may be something else. Or nothing. Thanks Ausir via The Vault.
