“The legal advice and expertise at Calderón & De La Sierra make it worthy of being among the best in the field”, enthuses one happy customer. The set is calibrated to provide the full range of patent services across a wide range of industries, and the team has made a superb name for itself on the back of its technical expertise, legal finesse and communication capabilities. Managing partner and a tenacious enforcer of rights, Carlos Pérez De La Sierra heads up the practice. A top-notch litigator, he is armed with a wealth of knowledge and expertise, which he readily shares with budding professionals in his capacity as a professor and a prolific author. Joining him on the contentious front is Alberto Huerta Bleck, who is equally confident handling civil procedures as he is fighting criminal and enforcement proceedings. Clients turn to him for strategic counsel and a depth of experience. Patent division lead César Ramos and senior patent counsel Ciara Cleary anchor the prosecution side. Ramos leverages the industry expertise he gained working for one of the largest telephone and internet companies in the world, and his profound understanding of the telecommunications and software markets, to dispense value-added and meaningful guidance to patrons. Cleary brings her specialist education in genetics and legal experience in biotechnology and pharmaceuticals to the table, and so gives the prosecution squad wide-ranging confidence in numerous technical fields.
