Partner / NEW YORK

Steven Wallach's litigation experience includes first-chair responsibilities at jury and bench trials and appellate argument.  Among his representations have been closely watched litigations regarding patenting e-commerce systems and copyrighting graphical user interfaces.  In addition to dozens of patent-infringement cases in the courts and the International Trade Commission and opposition proceedings in the Patent and Trademark Office, Mr. Wallach has worked on federal- and state-court actions concerning copyright and trademark infringement, trade-secret misappropriation, uncompensated use of ideas, and breach of contract.

A registered patent attorney, Mr. Wallach has represented clients ranging from start-ups to multinational companies.  Aside from litigation and opposition proceedings, his practice includes opinions, licensing, and counseling on patent, copyright, trademark, trade-secret, open-source, and e-commerce issues, and patent and copyright procurement.  He spent the first 17 years of his career in the Manhattan office of Pennie & Edmonds.

Since drafting and litigating the patent at issue in State Street Bank v. Signature Financial, much of Mr. Wallach’s practice has focused on computer systems, business methods, and software.  Technologies with which he has experience include client-server systems, semiconductor fabrication, nanotechnology, medical devices, NMR spectrometers, fMRI, vector network analyzers, inkjet cartridges and printers, polymer chemistry, and a variety of software programs and applications.

Mr. Wallach received a B.S. degree, cum laude, in Electrical Engineering (concentrating in Computer Science) from the Polytechnic Institute of New York, where he gained membership in the Tau Beta Pi and Eta Kappa Nu honor societies.  He also received a law degree from The George Washington University, where he was a winner of the intramural Giles S. Rich Intellectual Property Law Moot Court Competition, earning membership to the Moot Court Board’s Executive Committee.
