It is my honor to post the sixth annual US Utility Patent Toteboard.
The USPTO issued about 352000 US utility patents in 2020. 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 patents. It ranks the firms according to the number of US utility patents obtained in 2020. Each firm was invited in early 2021 to submit a simple online questionnaire. The closing date for the questionnaires was April 2, 2021.
Each firm was asked to report only US utility patents for which that firm is listed on the front page of the granted patent. The firms listed below, between them, accounted for about eleven percent of all of the granted US utility patents in 2020.
