答：为了维持您的商标注册，您必须在注册日后的第5年和第6年之间提交您的第一份维持文件，此后还需提交其他维持文件。联邦注册商标的权利可以无限期地持续下去，前提是您继续使用该标志并按时提交所有必要的文件和费用。

A: To maintain your trademark registration, you must file your first maintenance document between the 5th and 6th year after the registration date and other maintenance documents thereafter. Rights in a federally registered trademark can last indefinitely if you continue to use the mark and file all necessary maintenance documents with the required fee(s) at the appropriate times.
