About Marshall, Gerstein & Borun LLP

Premier Chicago intellectual property firm Marshall Gerstein advises a diverse client roster made up of Fortune 500 corporations, startups, small to mid-sized companies, nonprofits, universities, research institutions and independent inventors in its specialty areas of patents, transactions, trademark, and copyright protection and litigation. Located in Chicago's Willis Tower, the firm is an enduring part of both Chicago's skyline and the IP legal landscape. 

Major Players in Intellectual Property

Marshall Gerstein is that increasingly rare breed: a firm dedicated exclusively to the practice of intellectual property law. The firm works with clients in more than 150 countries on six continents. Founded in 1955 as Merriam & Lorch in the Chicago Board of Trade building, Marshall Gerstein originally focused on the electrical, chemical, and pharmaceutical industries. Over the next 60 years, the firm branched out and today covers patents in a wide array of industries including nanotechnology, genetics, optics, biochemistry, microbiology, computer and software engineering and medical devices. It has advised Procter & Gamble for 25 years, Amgen since its founding in 1980, GE, Pfizer, Merck Serono, Newell Rubbermaid Inc., and Northwestern University, among others.

Marshall Gerstein has been recognized by Chambers USA 2017 as one of the leading boutique IP law firms in the United States and several of the firm's attorneys have been recognized as leaders in their field by publications such as Fortune, Intellectual Asset Management Magazine, Intellectual Property Today and Corporate Counsel.  

Bring it All the Way to the Supreme Court

The firm has played a major role in historic Supreme Court cases in IP law, such as Walker Process Equipment, Inc. v. Food Machinery & Chemical Corp. and University of Illinois Foundation v. Blonder-Tongue Laboratories, Inc., and more recently, the landmark Amgen cases Amgen Inc. v. Hospira, Inc., Amgen Inc. v. Chugai Pharmaceutical Co., Ltd. and Amgen Inc. v. F. Hoffmann-La Roche Ltd.

A Culture of Science

Nearly all of our IP professionals have scientific or engineering degrees, and many have advanced degrees, including Ph.D.'s, allowing us to quickly master complex technologies. Staffing deals and cases with attorneys who understand the complexities of the inventions behind the patents is of prime importance to Marshall Gerstein.  Over 90 percent of the firm's attorneys hold degrees in science or engineering and many of those attorneys have past technical and scientific work experience at companies and institutions like Abbott Laboratories, AT&T, Bayer HealthCare Pharmaceuticals, Motorola, Inc. and the U.S. Air Force.

Samurai Warriors Will Protect your Patent

One client was so grateful for his Marshall Gerstein attorneys' refusal to back down on their defense of his patent, that he gifted them with a samurai suit of armor. The client, a surgery professor whose invention expanded skin tissue for the purpose of reconstructive surgery, explained that his attorneys had "represented him as loyally and fiercely as any Samurai warrior." He chose a suit of armor rather than a sword, he said, because he wasn't sure if the sword would get past security.
