Antitrust Civil Enforcement

  • Success in Prominent Matters for High-Profile Clients

    Our team successfully defended Google against the FTC's closely watched search investigation, which ended with the five commissioners unanimously voting that Google’s handling of its search results did not violate any U.S. antitrust laws.

  • A Leader in Single-Firm Conduct Issues and Civil Conduct Investigations

    Wilson Sonsini is widely regarded as the leading U.S. law firm for single-firm conduct issues, and represents a broad range of clients in civil conduct investigations both domestically and abroad.

Wilson Sonsini has an unmatched record of success representing clients before the DOJ, FTC, and foreign jurisdictions such as the European Commission in connection with the most high-profile civil non-merger investigations. Due to our extraordinary track record, we are regularly called upon to represent all manner of companies, either in connection with an antitrust agency's investigation into the company's business practices or in helping an agency investigate the conduct of others.

Most recently, our world-renowned antitrust team was retained to represent Google in connection with a landmark antitrust lawsuit filed in October 2020 by the DOJ and a group of 11 state attorneys general that accuses the company of maintaining an illegal monopoly over internet search and search advertising—a case widely regarded as the most aggressive action the U.S. government has taken against any technology company in years. The lawsuit has far-reaching implications not only for Google, but for Silicon Valley and the entire technology sector.

The DOJ’s lawsuit comes approximately seven years after the U.S. government last probed Google for antitrust violations, when Wilson Sonsini successfully represented Google in the FTC’s search investigation into the company’s business practices. In 2013, the FTC closed its 19-month investigation without bringing charges or seeking significant penalties after the five commissioners unanimously voted that Google’s handling of its search results had not violated the U.S. antitrust laws on any grounds. The FTC said that Google’s practices improved its search results for the benefit of consumers and that “any negative impact on actual or perceived competitors was incidental to that purpose.”

With our successful defense against the FTC’s search investigation of Google serving as a prime example, Wilson Sonsini is widely viewed as the leading firm in the United States for single-firm conduct issues. We are also frequently retained to represent clients—including Walgreens, Twitter, Symantec, Seagate, Spotify, Verisign, and Qualcomm, among others—in civil conduct investigations in both the United States and abroad.

As previously noted, the DOJ and FTC occasionally investigate the business dealings of our clients. Competitors, customers, suppliers, and distributors frequently bring their business concerns to the antitrust agencies, which in turn can result in substantial investigations into the legality of the challenged business conduct. It is important for our clients to secure representation to defend themselves not only before the antitrust agencies, but also in the all-too-often private cases that follow government enforcement actions. Our attorneys bring extensive experience and a deep understanding of the agency process to their representation of clients in these investigations. In addition, we assist clients who are the target of unfair business practices of competitors, suppliers, distributors, or other third parties who hamper their ability to compete. Bringing such behavior to the attention of the antitrust agencies is often an alternative to litigation, and can provide a swift and definitive resolution to such practices.
