Louis Klapp has litigated intellectual property disputes for nearly a decade. He is hardwired for tireless research and meticulous examination, which has driven his success as a litigator. Understanding that many complex cases hinge on subtle and complicated distinctions, he always arrives prepared.
Louis devotes his practice to patent, trademark, and trade secret disputes. He has represented clients across a wide variety of industries, including the software, consumer electronics, wireless communication, telephony, medical device, nutritional supplement, grocery, insurance, publishing, consumer products, retail, and automotive equipment industries. His patent cases have concerned technologies in the software, electrical, mechanical, optical, and biological fields.
Louis has engaged in all aspects of litigation from pre-filing investigation through appeal. He has litigated cases in many federal district and appellate courts, the United States International Trade Commission, the Patent Trial and Appeal Board, the Trademark Trial and Appeal Board, and the Judicial Panel on Multidistrict Litigation. In addition to his litigation work, he counsels clients on intellectual property issues, and he negotiates resolution of disputes without litigation.
Following law school, Louis was a Public Interest Law Initiative Fellow at the ACLU of Illinois. He maintains a pro bono practice focused on civil liberties and civil rights.
