Practice Area
Securities, M&A & Corporate Governance Litigation
In today’s market, litigators with experience in securities, corporate governance, and M&A-related (collectively, “securities litigation”) matters need to leverage their broad experience to serve as both advocate and as counsel and strategist, focused on helping clients to overcome not just a legal issue but a collective business problem. Given the frequent interplay between things such as corporate-control transactions, public offerings, activist shareholders, the use of complex derivatives and other financial instruments, bad news impacting stock performance, regulatory inquiries and investigations, and insurance coverage, strategic and tactical litigation decisions can have a wide-ranging impact on the success of a given transaction, as well as on companies, their boards, senior management, and advisors.

What Is Advertising Litigation?
Advertising litigation is defined as the legal area that covers false or deceptive advertising cases. Lawsuits may be brought by government agencies or corporate competitors based on the Lanham Act—a law that specifically deals with false advertising. The Act outlines how an advertisement can be deemed false. The Federal Trade Commission (FTC) has the ability to file lawsuits to halt deceptive advertising claims. The U.S. Food and Drug Administration may also pursue advertising litigation against violators of government regulations. Companies may be called on to substantiate their advertising claims, whether these are made in print or online.
