Given that a copyright application protects an author and has the "Pseudonymous" option, the legal claimant is always required in the form if you intend to have any legal protections, correct?
But a copyright is public information, like a patent. Often, inventors do not seek a patent for this very reason. Is this dilemma paralleled in copyrights? Can a pen name be both protected and not publicly outed, or are truly unknown pseudonyms in fact impossible?
