Our Story

We offer legal services built on a foundation of nearly 25 years of “Big Law” experience.

Mangum Ririe started in 2019 with the simple proposition that everyone deserves top-notch legal representation. The sort of representation honed by years representing some of the largest, most sophisticated business organizations on the planet in disputes of the highest stakes.

Our experience litigating and counseling in one of the most complicated areas of US law—intellectual property rights, including patents, trade secrets, trademarks, and copyrights—positions us to tackle whatever legal issues you need resolved, of any complexity. Add to that our significant experience litigating contract enforcement, defamation, and other general business disputes, and you have the perfect foundation for your integrated legal team.
