Biography: Mary B. Matterer has practiced patent litigation in the District Court of Delaware for more than 15 years. She frequently serves as Delaware counsel for law firms well known for their experience in patent and complex commercial litigation. Her practice consists of diverse forms of litigation, including intellectual property, commercial, and complex insurance coverage litigation. Mary primarily handles patent litigation across a wide range of industries, including pharmaceuticals, telecommunications, automotive, biomedical, electronics, and internet/software. She defended the City of Wilmington against a claim of copyright infringement brought by a former employee. The District Court of Delaware found on summary judgment that the copyright belonged to the city under the work made for hire doctrine, and that decision was affirmed by the Third Circuit Court of Appeals. She has also represented insurance companies in multimillion dollar disputes involving demands for coverage with respect to environmental and products liability claims under general liability policies, and also demands for coverage under directors and officers policies. She has served as Liaison Counsel for insurers where numerous insurers were brought into the lawsuit. She represented an excess insurer regarding liability for defense costs incurred by Intel in defending against claims of anticompetitive activity. Summary judgment of no liability for such costs was granted in favor of this and other insurers. Mary is praised by her clients, who appreciate her familiarity with the courts, as well as by judges who find her "confident, responsive, and flexible," according to Chambers USA - America's Leading Lawyers for Business, 2008. She was again cited by Chambers USA in 2012 "as a source of confidence; clients particularly highlighting her coolness under pressure and ability to make progress in a tense environment."
