Aldo is co-chair of the Technology Antitrust Group and a first-chair trial lawyer with 40 years of experience litigating cutting-edge issues at the evolving intersection of IP, antitrust, and technology. He represents clients in the high-tech, pharmaceutical, metals/mining, and food industries. Admitted in California, New York, and D.C., Aldo has spent significant time practicing in Northern California. He is also an adjunct professor at the University of New Hampshire Franklin Pierce School of Law, teaching a class that focuses on trying cases at the antitrust–IP nexus.

Aldo’s principal areas of practice include antitrust and unfair competition litigation, patent and fair, reasonable, and non-discriminatory (FRAND) litigation, complex commercial litigation, arbitration, and contract disputes. He has extensive experience in the preparation and trial of complex cases to judges and juries.

Aldo has four decades of experience litigating antitrust cases involving a wide variety of issues, including those affecting intellectual property rights. He has extensive experience litigating Sherman Act Section 1 and 2 cases in numerous industries, including the cloud computing and software, steel, coffee, pharmaceuticals, health care, and electronics industries. He has successfully defended clients against predatory pricing allegations and has litigated Robinson-Patman and federal and state antitrust cases as well as antitrust cases involving standard essential patents (SEPs), patent pools, and FRAND disputes.

Aldo leads the joint prosecution group in one of the nation’s largest MDL antitrust cases. He has also served as trial counsel for a major pharmaceutical manufacturer in a landmark 10-week Sherman Act antitrust jury trial in which the court granted defendants’ motion for judgment as a matter of law. In that case (In re Brand Name Prescription Drugs Antitrust Litigation), potential damages in the tens of billions of dollars were sought along with injunctive relief, arising out of claims that various pharmaceutical manufacturers and wholesalers had conspired to deprive retail pharmacies of discounts for brand name prescription drugs.

As for patent litigation, Aldo has been involved in numerous software, semiconductor, biotechnology, and medical device patent matters. His experience includes jury and judge trials, Markman hearings, and IP due diligence and licensing negotiations including, most recently, two federal jury trial victories involving false advertising in the IP context and an ICC arbitration victory relating to a licensing dispute over a small molecule drug patent.
