It is my honor to post the seventh annual US Trademark Registration Toteboard.
The USPTO issued about 367965 US trademark registrations in 2021. The goal of this toteboard, brought to you by the Ant-Like Persistence blog, is to list the firms that helped clients to obtain these registrations. It ranks the firms according to the number of US trademark registrations obtained in 2021. Each firm was invited in early 2022 to submit a simple online questionnaire. The closing date for the questionnaires was February 2, 2022.
