Trade secrets cannot be registered anywhere. That is, there is no agency that grants or recognizes trade secrets. Rather, to qualify for trade secret protection, the information must be used in business, provide a competitive advantage and be treated as a trade secret. A federal or state court may enjoin a person suspected of disclosing a secret in violation of a duty of confidentiality. Right of publicity rights are enforced according to state laws.
Privacy laws exist at both the state and federal levels.
You do not need to take any action to validate your copyright. D.C. Registration can be used to notify others of your intention to exert control over the work. The most compelling reason to register quickly is that you can not sue for relief from infringement until the work is registered, and if the work was registered prior to the infringement, you are able to seek high compensation with less proof of actual damages. Also, the Copyright Office is an office of public record, so registration provides substantial credibility to any claim of copyright. The Copyright Office of the Library of Congress is in charge of the administration of copyrights.
