Rosario Avveduto

Of Counsel | Intellectual Property

Rosario is a key member of the Han Santos IP practice, and specializes in tech transactions, copyrights, and trademark. 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 European office.

Rosario’s US law expertise covers several soft IP fields including: copyrights registrations, code versioning protocols and software copyright protection, code-based transformative/fair uses and derivative works, due diligence in IP-driven corporate transactions, and international trademark prosecution. Through his growing practice, Rosario works closely with tech start-ups that have global reach, standards setting organizations, European cosmetics companies, EdTech and innovative educators, and minority-owned companies creating digital tools for their communities.

Rosario’s law career began in his native Italy, where he plans to be cross licensed by the end of 2021. 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. approach to litigation and contributed to several transactions such as: employment contracts, real estate agreements, or extrajudicial settlements.

In 2018, 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 graduating.

Upon obtaining his license, Rosario began working as a solo IP and trademark attorney focusing on strategizing and pursuing trademark applications, overcoming office actions, and drafting IP-centered agreements for clients in the United States, the European Union, and Asia.

In 2019, Rosario was published in the Washington International Law Journal, Volume 29, with an article exploring the interplay between international space law and patent laws, criticizing the obsolescence of space law tenets (Cited as: Rosario Avveduto, Past, Present, and Future of Intellectual Property in Space: Old Answers to New Questions, 29 WASH. INT’L L.J. 203 (2019)).

Outside of work, Rosario enjoys hiking, biking, and snow sports, especially cross-country skiing. He also practices martial arts and never fails to carry a book with him for company. When home, he cooks, watches his favorite shows, and enjoys gaming.

As a member of Han Santos, Rosario is now further developing his business and corporate law expertise, oriented towards transactions and services centered on IP, corporate, and licensing.
