Major Players in Intellectual Property

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. Chugai Pharmaceutical Co., Ltd. and Amgen Inc. v. F. Hoffmann-La Roche Ltd.

A Culture of Science

Only those with scientific and technical educational backgrounds need apply: staffing deals and cases with attorneys who understand the complexities of the inventions behind the patents is of prime importance to Marshall, Gerstein & Borun. Two of the firm's current name partners hold degrees in fields like biology and nuclear engineering, associates have past non-legal work experience at companies and institutions like AT&T and the U.S. Air Force and over 90 percent of the firm's attorney pool hold degrees in science or engineering. In addition, over 80 percent of the firm's agents and technical specialists have Ph.D.s or other advanced technical degrees.

Samurai Warriors Will Protect your Patent

One client was so grateful for his Marshall Gerstein & Borun 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.
