AT&T Sues Verizon Over 3G Ads: Report

ATLANTA (TheStreet) -- AT&T (T Quote) filed a lawsuit against Verizon Wireless alleging the use of "misleading" coverage maps in advertisements that are costing AT&T market share, according to a Reuters report.

The suit, filed in Atlanta Federal Court, claims that the Verizon ads use comparison maps with white spaces that wrongly suggest that AT&T offers no coverage in areas where it does not provide high-speed 3G mobile service, Reuters reported.

Responding to the claim, Verizon stated that the ads make clear that voice and data services are available outside 3G areas, but are intended to compare high-speed coverage for smartphones, according to Reuters.

AT&T has asked the court for a temporary restraining order while the court confirms a date for a preliminary and permanent injunction hearing.

Verizon Wireless is a venture of Verizon Communications (VZ Quote) and Vodafone (VOD Quote).
