IP firm Espinosa Martinez PL won a major victory in a patent infringement lawsuit, Tawnsaura v. Vitacost.com, for the firm’s client, Vitacost.com, an online vitamin supplement retailer, who was sued by a California-based non-practicing entity (NPE). Patent attorney William R. Trueba Jr., a founding member of the firm, argued the case. On June 13, 2014, the Hon. Judge S. James Otero ruled that Tawnsaura Group's claims of two nutritional supplement patents for a vitamin supplement called L-citrulline were invalid on the basis of prior technology and prior knowledge of the claimed methods. During the hearing, Judge Otero ruled from the bench -- an uncommon occurrence in patent infringement cases. According to Trueba, the ruling sends a message to non-practicing entries that "defending against meritless patent infringement claims might be the better approach over settling." Tawnsaura filed suit in mid-2012 against more than 85 defendants that sell nutritional supplements nationwide. Dozens of defendants had settled with Tawnsaura prior to the hearing and agreed to pay licensing fees to the company. Press Release.
