Biography
CO-CHAIR, INTELLECTUAL PROPERTY LITIGATION PRACTICE GROUP
Domingo M. LLagostera is the co-chair of the Intellectual Property Litigation group at Blank Rome and a lead trial lawyer who concentrates his practice on patent and trade secret litigation from filing through appeal. Domingo practices IP litigation in a wide variety of technical fields, including complex oil and gas, semiconductor, software and hardware, pharmaceutical, medical, and mechanical technologies. Domingo has effectively represented all of these technology areas in litigation, including in several trials.
First and foremost, Domingo has a passion for both enforcing and defending company innovations. He has represented both plaintiffs and defendants through all phases of patent and trade secret litigation in federal court from coast to coast. Domingo develops close and trusted relationships with his clients, providing business advice, and cost-effective strategic solutions related to all things IP. He also counsels clients in pre-suit advocacy and early resolution strategies so that his clients avoid the high costs of litigation, including using defensive strategies such as inter partes review before the U.S. Patent & Trademark Office.
In addition to adversarial work, Domingo is also active in a wide range of intellectual property investigative and transactional work, including: IP consulting, IP opinions, IP landscape evaluations, pre-suit competitor investigations, IP transactions, and patent prosecution.
A prior life on the road as a rock musician has given Domingo great insight and empathy for those who create and develop what is new and unique. He is passionate about protecting some of the most valuable company assets, intellectual property.
