Rosetta Stone v. Google, 676 F.3d 144 (4th Cir. 2012) was a decision of the United States Court of Appeals for the Fourth Circuit that challenged the legality of Google's AdWords program. The Court overturned a grant of summary judgment for Google that had held Google AdWords was not a violation of trademark law (see federal Lanham Act,15 U.S.C. § 1114(1)).
