Verizon Wireless has asked a U.S. court for a judgment to determine whether its "America's Most Reliable 3G Network" ads are truthful as AT&T has charged they are misleading. Verizon filed its lawsuit in the U.S. District Court in Manhattan in response to AT&T's claims that Verizon's advertising was false and could not be supported. On July 1, according to the claim, AT&T filed a challenge with the National Advertising Division of the Council for Better Business Bureaus, and sought to have Verizon's advertising declared false. However, Verizon countered that its claims of having "America's Most Reliable 3G Network," "America's Best 3G Network" and "America's Most Reliable Wireless Network" are "truthful, accurate and substantiated," and are not in violation of the trademark law known as the Lanham Act. Verizon said that AT&T's claims were based on a false premise that speed is an essential element in measuring network reliability. Article
