Cornerstone Research’s antitrust and competition practice comprises 98 specialists across eight offices in the United States and Europe. Andrea Shepard in the San Francisco office and Rahul Guha in New York co-head the group. Competition experts represent approximately 24 per cent of the firm’s consultants.

Over the past year, Cornerstone Research has advised clients on regulatory issues in twelve mergers, including major transactions in media and telecom services, high-tech, energy markets and food distribution services. The group has been active in cases at the intersection of antitrust and intellectual property, including work on several patent matters involving smartphones, standard essential patents and the use of an injunction as a remedy. In collaboration with its finance practice, its economists also work on competition issues arising in matters involving financial institutions, including Libor, foreign exchange, credit default swaps and private equity cases. The firm has also worked on a number of cases involving allegations of vertical and horizontal conspiracy in other industries, including agriculture, consumer products, electronics, telecoms, auto parts and air cargo. In many of these cases, the group has worked on both the class certification and merits phases.
