Thus, in many States, the law applicable to ownership of intellectual property is the law of the State where the intellectual property is protected (lex protectionis), while the law applicable to contractual matters is the proper law of the contract (lex contractus).
因此在许多国家，知识产权所有权的适用法律是知识产权保护国的法律（保护国法），而合同事项的适用法律是合同准据法（合同地法）。
