#9 for Utility Patents

Out of hundreds of U.S. law firms, Cantor Colburn ranks #9 for U.S. utility patents issued in 2023. Cantor Colburn has been in the top 10 for utility patents issued for over a decade.

Ant-like Persistence publishes annual "Toteboards" of patent and trademark rankings. Cantor Colburn ranks #5 for design patents and #11 for trademarks. Significantly, no other law firm ranks higher in all three categories.

Ant-like Persistence, a must-read IP blog, identifies its criteria:

The USPTO issued about 312,095 U.S. utility patents in 2023.  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 2023.  Firms report only US utility patents for which that firm is listed on the front page of the granted patent. The firms in this ranking accounted for about twelve percent of all of the granted U.S. utility patents in 2023.
