Counsel - Litigation and Investigations

Sebastian litigates disputes concerning trademarks, copyrights, trade secrets, and complex commercial transactions. He represents clients in both federal and state courts and has successfully resolved claims at all stages from pre-litigation cease and desist letters through trial. In addition to intellectual property litigation, he defends technology innovators from privacy, false advertising, and other consumer-related class actions.

Sebastian is an active member of local and national bar associations. In 2016, he was appointed by the president of the American Bar Association to sit on the Advisory Commission of the Standing Committee on Public Education. He is a director of the Justice and Diversity Center of the Bar Association of San Francisco (“BASF”) and chair of the BASF Intellectual Property Section. In 2013, he served as the president of BASF’s Barristers Club, comprised of BASF attorneys with less than ten years of practice, and was named Outstanding Barrister of the Year in 2016.

He is also committed to pro bono homelessness prevention and regularly represents indigent tenants facing eviction. In 2015, Sebastian was awarded BASF’s annual Housing Justice Award for first-chairing a four-day unlawful detainer trial.
