Mario Vasta works in our business litigation and intellectual property practice groups. He focuses primarily on civil litigation, including resolving business, contract, and real estate disputes. He also represents clients in domestic and international intellectual property litigation matters, including dealing with trademark and copyright issues, cancellation and opposition actions before the U.S. Patent and Trademark Office, and counterfeiting issues. Mario is also the go-to attorney for companies battling scam artists trying to use confusingly-similar website names to divert customers and disrupt business. He navigates through legal and administrative processes to take down these imposters, while protecting his clients’ vital brands. In keeping with our proud history in natural resources, Mario’s practice also includes water rights litigation, and his work on behalf of farmers in eastern Arizona has legal precedents dating back to the 1920s.

At the early age of 12, Mario knew he wanted to be an attorney. Mario consistently honed his reading, writing and public speaking skills with his eye on becoming the first attorney in his family. Raised in Upstate New York, he always knew he wanted to head out West. After graduating from Cornell University, Mario drove his Pontiac to Phoenix, Arizona, where he graduated first in his class at Arizona State University’s Sandra Day O’Connor College of Law. Feeling like he found his true calling as a business litigation attorney, Mario takes great satisfaction in working with clients to creatively and efficiently resolve all types of disputes.

When he is not busy helping clients, Mario is usually spending family time with his three sons and Australian cattle dog. He recharges his batteries in the great outdoors with activities like hiking and kayaking. An avid reader, Mario collects books (physical ones!) and his home library includes a wide range of scientific and historical nonfiction titles – plus the occasional science-fiction novel.
