答：如果您是外国注册人，那么是的，您必须由一名在美国有执业资格的律师代理。如果您在美国或其领土注册，那么不是必须的。但我们强烈建议您聘请一名专业的美国执业律师来指导您完成申请过程。
A: Yes, if you are foreign-domiciled. You must be represented at the USPTO by an attorney who is licensed to practice law in the United States. No, if you are domiciled in the United States or its territories. Although you are not required to have an attorney, we strongly encourage you to hire a U.S.-licensed attorney.
