Craig Wright has filed a copyright claim with the US Copyright Office in the United States on the Bitcoin White Paper. According to Emin Gün Sirer, professor at Cornell -Ithaka New York, it is specified that according to the Berne Treaty, copyright belongs to the author and that the deposit of copyright for the original content is unnecessary. Copyright does not imply authorship and does not mean that the plaintiff created the content.
Intellectual property expert Alex Meijas says that once you have received a patent, all derivative works are also legally owned by you. This means that Craig Wright can potentially sue Bitcoin Cash and other forks for violating his work.
