Shipping and Transit, LLC sued Acer and Brown-Forman, as part of a recently launched campaign. The entity filed three suits on April 27, 2015, and within two weeks it had more than a dozen suits. Each case asserts four patents concerning notification systems for tracking a vehicle (6,904,359, 6,975,998, 7,030,781, 7,400,970). Shipping notification services that defendants provide to customers are at issue in the suits.
