Yahoo also lobbied on a proposed online advertising partnership with Google Inc., which the companies recently abandoned in the face of a looming antitrust challenge being prepared by the Justice Department.

In addition, the Sunnyvale, Calif.-based company lobbied on proposals to crack down on phishing scams, which use fake e-mails and fraudulent Web sites to trick consumers into releasing credit card numbers and other personal information. Yahoo also lobbied on patent reform and other intellectual property issues.

Besides Congress, the company lobbied the departments of Commerce and Justice, the Federal Communications Commission, Federal Trade Commission and other agencies, according to the disclosure form filed Oct. 20 with the Senate's clerk office.
