The decision between protecting a nanotechnology innovation as a trade secret or a patent depends on several factors: - Duration: Trade secrets can last indefinitely, while patents have a limited term (usually 20 years). - Disclosure: Patents require full public disclosure of the invention, whereas trade secrets remain confidential. - Cost: Patents can be expensive to obtain and maintain, while trade secrets generally involve lower costs. - Enforcement: Patents provide stronger legal protection against infringement, whereas trade secrets rely on maintaining confidentiality.
