The story

Banner Witcoff traces its history from 1920, in Des Moines, Iowa. The company's name was chosen when two regional intellectual property law firms, Allegretti & Witcoff and Banner, Birch, McKie & Beckett, joined forces to create a national firm. The firm opened the Chicago office of Banner & Witcoff in 1937. Subsequent offices were opened in Washington, DC (1960), Boston (1985), and Portland (1997).

In 2021, the firm announced the election of firm president, Binal Patel.
