Mr. Lowenstein’s practice is wide-ranging, with emphasis on defending and counseling clients in professional malpractice, securities and antitrust matters.

In 2013, 2014 and 2015, Southern California Super Lawyers magazine named Mr. Lowenstein a Rising Star in the field of business litigation.
Mr. Lowenstein’s key representations include:
- Bank of America against several mortgage-backed securities lawsuits, including $10 billion in claims asserted by AIG.
- An online retailer against claims that it violated the antitrust laws by commencing “sham litigation” against its competitors. The court granted the retailer’s motion to dismiss with prejudice.

- A large telecommunications provider against a consumer class action alleging false advertising. The court granted summary judgment.

Mr. Lowenstein has also counseled clients, including leading entertainment studios, on antitrust compliance in connection with trade association activity, retail programs and a proposed merger.
