Rosario’s work with the firm includes establishing a two-way corporate, tech, and IP practice between the United States and the European Union as well as establishing a future European office.
Rosario’s law career began in his native Italy. His background and experience encompass counseling, transactional practice, and litigation. After graduating with a marked inclination towards international law, Rosario worked at a general practice firm in Italy. There he adapted the U.S. inductive method to civil and criminal litigation. He also contributed to several transactions such as: employment contracts, real estate agreements, or extrajudicial settlements.
After an exchange program at the University of Washington (UW), Rosario decided to move to Seattle to pursue a Master’s Degree (LL.M.) centered on Intellectual Property. He obtained his Washington Bar license soon after.
Upon graduation from UW, Rosario began working as a solo IP and trademark attorney. His practice focused on strategizing and pursuing trademark applications, addressing and overcoming office actions, and drafting IP-centered agreements for clients in the United States, the European Union, and Asia.
