My goal when working with clients is to make the experience a collaborative one, keeping them up-to-date and garnering their valuable input while taking the pressure of the litigation grind off their shoulders. I think that communication and clarity are key, and strive to bring those qualities to every matter that I work on. Quotation mark

About Delfina

Delfina Homen is an intellectual property litigator and has represented clients from diverse industries in lawsuits involving patent, trademark, and copyright infringement, trade secrets, unfair competition, and tort and contract disputes. She also advises and represents clients in trademark opposition and cancellation proceedings before the Trademark Trial and Appeal Board and patent inter partes review proceedings before the Patent Trial and Appeal Board.

Additionally, Delfina uses her advocacy skills and intellectual property knowledge to advise and represent clients in the international sphere, helping clients protect their intellectual property and defend their products with U.S. Customs & Border Protection and the International Trade Commission. Through her work in these administrative proceedings, Delfina has developed an understanding of regulatory issues not seen in the typical litigation, and can provide clients with valuable insights as a result.

Delfina also brings her considerable breadth of IP knowledge to the firm’s Privacy & Data Security Team and its Cannabis Team.

Delfina understands that not every matter is destined for litigation. She partners with clients to obtain favorable resolutions for each unique situation. Delfina has successfully represented clients in private and court-ordered mediations. She also has experience drafting, reviewing, and negotiating trademark usage agreements, litigation settlement agreements, and licensing agreements.

Outside of litigation, Delfina is experienced in IP procurement and enforcement. She has worked on numerous trademark and patent applications, assisting clients in obtaining the IP protection they need to grow and support their business strategies. Delfina has also organized and run large trademark, patent, and copyright enforcement programs for national companies.

Before law school, Delfina worked as an undergrad research assistant at Oregon State University and then after college as a research assistant at Shriner’s Hospital for Children and Oregon Health & Science University.
