Notable Representations, Key Contacts

Weil offers global solutions to our clients’ Antitrust/Competition transactional needs with one of the largest, most diversified and well-respected practices in the world. Trusted with many of the largest mergers in the last two decades, we bring to bear a combination of law firm and public-sector experience.

We coordinate multi-jurisdictional filings to assure maximum chances for swift approval and protect our clients against the adverse effects of mergers through effective advocacy before various governmental agencies.

We help clients structure transactions and business practices that minimize antitrust concerns. Collaborating with lawyers in practices including Mergers & Acquisitions, Intellectual Property, Business Finance & Restructuring and Public Company Advisory Group, we provide integrated solutions to competition-related business issues.

Former Government Officials

Many of our partners are high-level government antitrust officials and formerly headed divisions at the Federal Trade Commission, responsible for review of mergers and acquisitions in numerous industries, including pharmaceutical, medical device, biotechnology, aerospace, defense, industrial, scientific, technology, retail, hospitals and consumer products.

This background provides the group with significant experience and insight into the merger review process and the substantive analysis that may be applied to transactions in these and other industries.

Shaping U.S. Antitrust Policy

Our team has been at the forefront of U.S. antitrust policy and procedure for many years, and while in important government positions assisted in developing the government’s approach to merger enforcement, influenced the body of Hart-Scott-Rodino rulings, and designed the government’s merger discovery process.

International Competition

Our Antitrust/Competition international network helps multinational companies meet the challenges of globalization, including increased scrutiny of mergers and acquisitions by regulatory agencies throughout the world. We have achieved significant success before major authorities and courts in the U.S., Europe, and many other jurisdictions.

With competition lawyers in the United States and European Union, Weil has the international reach and experience to handle multinational reviews of mergers and acquisitions.

In countries where we do not have offices, we have developed strong and effective collaborative relationships with the best local competition law firms.
