Using their deep understanding of today’s global economy and the intricate relationships among competing and cooperating businesses, Shartsis Friese’s antitrust litigators protect our clients’ interests in an increasingly complex legal landscape.
We represent clients in high-stakes antitrust and unfair competition matters under the Sherman Act, Cartwright Act, and related federal and state laws.
We handle disputes and investigations involving:

- Tie-ins and refusals to deal
- Mergers and acquisitions with antitrust implications
- Price discrimination
- Unfair competition claims under California Business & Professions Code §17200, including cases involving trade secret misappropriation and employee solicitation
We also frequently advise clients on issues at the intersection of antitrust and intellectual property, including distribution, licensing and competitive conduct in technology-driven markets.
On the transactional side, we provide strategic antitrust counseling to help clients comply with:
- The Sherman Act, Clayton Act, and Robinson-Patman Act
- Hart-Scott-Rodino (HSR) premerger notification requirements
- Product distribution, dealer termination and other trade regulation issues
Our goal is to help clients navigate complex antitrust risks, minimize exposure and achieve their business objectives in an increasingly interconnected marketplace.
