He has also defended attorneys—from international Am Law 100 firms, regional boutiques, and plaintiff-side firms—in major legal malpractice lawsuits, partnership disputes, and disqualification and sanctions disputes.

In 2021, Matan was named a Law360 Rising Star, including for his work defending Qualcomm in a month-long antitrust trial and a related consumer class-action.
