A member of the firm’s Intellectual Property group and a registered patent attorney, Mark Thomas focuses on litigation of complex intellectual property matters pending in state, federal and appellate courts throughout the United States. Within this area, he prosecutes and defends claims of patent infringement, copyright infringement, trademark infringement and trade secret misappropriation for individuals and private and public companies involving a wide array of technologies in the mechanical, electrical and chemical arts.
Much of Mark’s practice involves patent work. In addition to handling all phases of litigation, he prepares non-infringement and invalidity opinions and patentability, due diligence, and patent landscape analyses. In these matters, he assists clients in pre-litigation enforcement of patent rights by performing initial infringement analyses, providing tailored patent enforcement strategies, preparing cease and desist letters, and negotiating settlement agreements.
Prior to joining the firm, Mark was in private practice at a boutique intellectual property law firm. In his previous career, he taught high school Biology at a St. Louis area private school.
