Sidney A. Rosenzweig

Sidney A. Rosenzweig is a long-serving government attorney with the U.S. International Trade Commission's (ITC) Office of the General Counsel. His practice is focused on Section 337 investigations, which involve claims of unfair importation of goods, including patent and trademark infringement. His public record shows involvement in cases spanning a wide range of technologies, from mobile electronic devices and semiconductors to lighting products and DC-DC controllers.

As counsel for the ITC, Mr. Rosenzweig exclusively represents the agency in its governmental capacity. This role is inherently defensive when the Commission's final determinations are appealed to the U.S. Court of Appeals for the Federal Circuit. The provided data shows him appearing for the defendant, the ITC, in Bissell Inc. v. International Trade Commission. That case involved an appeal of the ITC's findings related to patents on wet-dry surface cleaning devices, where the Federal Circuit affirmed the Commission's determination of non-infringement for redesigned products.

Mr. Rosenzweig's entire tracked career appears to be within the ITC's Office of the General Counsel, where he has been listed as a contact attorney on official notices for over a decade. His work is concentrated on litigation and appeals originating from the ITC, and there is no public record of him representing private parties or practicing before the Patent Trial and Appeal Board (PTAB).

Information regarding Mr. Rosenzweig's education and bar admissions is not available in readily searchable public sources.
