Her advertising cases have spanned a very broad spectrum of products and services including prescription drugs and biologics, molecular diagnostic assays, over-the-counter drugs, razors, toothpaste, paint, pet food, chocolate, cosmetics, financial services, cell phone cases, luxury goods and consumer electronics. Randi has represented and counseled clients on a wide variety of copyright and trademark matters, encompassing classic ownership and fair use issues for works including comic books, academic works, reality television, music and photographs, as well as artificial intelligence, keyword advertising, online advertising and regulation, Section 230 issues, web scraping, and the intersection of privacy and intellectual property. She represented eBay in Tiffany v. eBay, the landmark case in secondary trademark liability, and is regularly called upon by major internet platforms for help navigating a complex array of secondary liability concerns.
