Stone Pigman provides comprehensive antitrust litigation and counseling services. We have represented both plaintiffs and defendants in a broad range of antitrust cases, including class actions, criminal enforcement actions and technology disputes. In the area of antitrust counseling, we have provided a large variety of businesses with advice on antitrust issues.

Our clients come from diverse industries, but are alike in their need for competent antitrust counsel -- especially as federal antitrust agencies become more aggressive in investigating business activity for potential anticompetitive effects.  We can provide that counsel by representing you in litigation and before enforcement agencies, in sensitive internal investigations and government inquiries.  Our lawyers also can advise your business in mergers and other transactions with antitrust implications.  We can also challenge the anti-competitive practices of other companies where necessary to protect your interests.  We assist businesses by providing preventive risk assessments, and advice on complex issues such as distribution and licensing, the regulation of unfair trade practices and intellectual property matters.

Our lawyers strive to quickly gain an in-depth understanding of your business needs and focus on the best results for you.  By combining the knowledge and experience of our antitrust litigators with the business and regulatory knowledge of our corporate and tax attorneys, we can bring a complete multidisciplinary perspective to your antitrust and competition issues.
