Jonathan E. Sommer is the former Chair of the Litigation Group at Lubin Olson. He has a wide-ranging commercial litigation practice, with emphasis on real estate, securities fraud, anti-SLAPP motions, and business torts and contracts. His practice has ranged from smaller cases involving disputes among partners and start-up businesses to larger cases against some of the most formidable investment banks and hedge funds in the world. In larger cases, he has teamed up with his partners at Lubin Olson to oppose national law firms such as O’Melveny & Myers, Boies Schiller, Sullivan & Cromwell and many other top law firms. The full transcript of one of his depositions of a hedge fund manager was featured in the New York Times.
Mr. Sommer has litigated in state and federal trial and appellate courts and before private arbitration panels. In addition to real estate, securities and anti-SLAPP matters, he has litigated cases involving partnership disputes, officer and director liability, defamation and business disparagement, landlord-tenant, land use, trade secret theft, mergers and acquisitions, unfair competition, false advertising, construction, patent licensing, accounting malpractice, franchise agreements and insurance coverage.
