Shareholder McPherson Moore (“Mac”) joined Sandberg Phoenix in 2018. Prior to working with his previous firm which he joined in 1995, Mac worked as a Design Engineer for Newport News Shipbuilding & Dry Dock Company (a division of Tenneco) in Newport News, Virginia. His work in Newport News concerned the conversion of submarine missile launching systems from Polaris Missile to Poseidon Missile accommodation.

Mac chaired the Intellectual Property Department at a large St. Louis general practice law firm, and prior to that was a partner with the St. Louis intellectual property law firm Rogers, Howell, Moore & Haferkamp.
Mac focuses his practice on litigating patent, trademark, trade dress, unfair competition, franchise, trade secret and copyright cases from the plaintiff’s and defendant’s standpoint. He has represented clients in litigation resulting in awards of $1,000,000 or more. This includes a $15,000,000 verdict for patent infringement, one of the largest patent infringement verdicts in Missouri, as well as a settlement in the Robert Morley vs. Square trade secret/patent lawsuit of $50,000,000, both in the Eastern District of Missouri.

The Meridian Patent was tested in litigation, including an award in Meridian’s favor of $21 million dollars in U.S. District Court. Mac also drafts intellectual property agreements including licenses, assignments, nondisclosure agreements, consulting and independent contractor agreements, agreements on employee obligations and covenants not to compete.
