Exergen Corporation vs. Kaz, USA, Inc.

United States District Court for the District of Massachusetts

Sunstein’s trial team won a jury verdict for our client Exergen, resulting in a $16 million judgment against Kaz, the maker of consumer products sold under the Vicks and Braun brands. Despite Kaz’s multiple challenges to the twelve patent claims asserted by Exergen, the jury upheld the validity of all of them, and found that the forehead thermometers sold by Kaz infringed those claims. Exergen is a Watertown, MA-based manufacturer and seller of thermometers for both the professional and consumer markets.
