Antigone Peyton, Founder and CEO

Antigone focuses on intellectual property litigation and IP portfolio management and growth strategies involving patents, trademarks, trade secrets, and copyrights. Her litigation and counseling experiences also include unfair competition, DMCA violations, computer fraud, and social media issues. Antigone has acted as lead trial counsel and appellate counsel in federal civil lawsuits across the United States and has a significant litigation practice in the Eastern District of Virginia (the “Rocket Docket”). Additionally, Antigone has represented clients before the Patent Trial and Appeal Board (PTAB), in the U.S. Patent and Trademark Office (USPTO), and before the Trademark Trial and Appeal Board (TTAB).

Antigone has been recognized among Virginia Super Lawyers and Virginia Legal Elite for her work involving intellectual property law. She has also been honored with an Influential Women of Virginia award for outstanding efforts in law and her community contributions, which includes a STEM mentorship program for students interested in careers involving scientific research and innovation.

Antigone’s clients range from technology start-ups to international corporations. She has represented companies involved in high stakes intellectual property litigation over technologies that range from pharmaceuticals and medical devices to Internet, software, cyber security, telecommunication, and aerospace technologies. Antigone has significant experience involving e-discovery related technologies and practices. She has also helped consumer products companies manage and grow brand-related assets, including companies focused on fitness, food, cosmetics, and apparel products.

Having worked for both a trial judge at the U.S. International Trade Commission (ITC) and an appellate judge at the Court of Appeals for the Federal Circuit (Federal Circuit), Antigone brings a practical perspective to her litigation and client counseling practice.

Before she founded Cloudigy Law, Antigone was a litigator at Finnegan, Henderson, Farabow, Garrett & Dunner LLP, in Washington, DC and managed the firm’s electronic litigation working group on e-discovery. Before law school, Antigone conducted scientific research involving clinical and pre-clinical biophysics and magnetic resonance studies at a large university medical center. This experience sharpened her focus on business needs and the practical aspects of innovation efforts when crafting legal solutions—a perspective often missing in the legal field.

She does much more than legal work, though. Antigone is an avid fruit and vegetable gardener and enjoys growing heirloom tomatoes in the summer.
