REPRESENTATIVE MATTERS
Commercial Litigation
- Represented emergency room physicians and won a $62.6 million jury verdict in a Nevada state court case that attracted national media attention. After a seven-week trial, the jury unanimously found malice, oppression, and fraud against United Healthcare for the systematic underpayment of emergency room services. This verdict will serve as a bellwether for more than two dozen similar cases against several insurers nationwide.
- Represented emergency room physicians and won a $19.1 million Houston jury verdict against a large insurance company. This case was the first in the nation to litigate the amount that private insurance companies should pay for out-of-network emergency services under the Affordable Care Act.
- Defended former executive of offshore service company against noncompete and trade secret claims.
- Defended property owner against premises liability claims in a personal injury lawsuit.
Intellectual Property Litigation
- Represented patent owners in lawsuits against major smartphone and semiconductor manufacturers. In several of these lawsuits, Mr. Liao actively handled matters from filing until resolution and has helped recover over $45 million for AZA’s clients.
- Represented patent owner in multimillion-dollar lawsuit against prominent cellular network operators. Mr. Liao took on lead roles in opposing the defendants’ challenge to invalidate the patents under 35 U.S.C. § 101 and rebutting their claim construction arguments at the Markman stage. The case settled favorably after the Markman hearing.
