Antheros Legal: Fast, Fluent, Friction-Free IP Strategy for Life Sciences

SAN FRANCISCO, CA – May 19, 2026 – Antheros Legal, an AI-native intellectual property (IP) law firm, today announced its official launch, bringing Big Law strategic depth to growth-stage life sciences companies. Free of the slow timelines, rigid structures, and misaligned incentives that cost innovators their competitive edge, the firm is built specifically for startups and the investors who back them.

Antheros was built by and for innovators. The firm is AI-native, using advanced tools to streamline IP research, eliminate low-value tasks, and produce high-quality deliverables faster than traditional firms, giving clients the responsiveness of a startup with the rigor of a top-tier law firm. Scientific fluency melded with legal expertise is built into every engagement: Antheros’ practitioners understand the science and deploy legal strategies tailored to each client’s scientific and business goals.

Antheros serves startups, emerging companies, and investors driving breakthroughs in therapeutics, medical devices, tissue and cell engineering, food technology, diagnostics, and digital health. Combining AI-powered workflows with deep sector expertise, the firm designs IP strategies that both protect ideas and build defensible patent estates that move as fast as the science does.

“Rote IP strategy slows companies down. We built Antheros on the belief that great IP strategy should be as creative and fast-moving as the science it protects,” said Sabrina Poulos, Founder and Managing Partner of Antheros Legal.

Founded in July 2025, Antheros is led by Sabrina Poulos, Stephanie Dusaban Gonzales, Ph.D., and Kristin Havranek - three scientists-turned-attorneys-turned-entrepreneurs who left Big Law to build a better firm. All three built their legal careers at Wilson Sonsini and Goodwin Procter, two of the most respected IP practices in the country for life sciences; Sabrina as an associate and partner at Wilson Sonsini and then partner at Goodwin; Kristin as an associate at Wilson Sonsini, and then partner at Goodwin; and Stephanie as a patent agent and then associate at Wilson Sonsini and Goodwin. Together, with a broader team of nine professionals who share the same Big Law pedigree, Antheros helps clients create IP portfolios built to support commercial success: legally sound, scientifically rigorous, and designed to grow in value as their companies do.

“Antheros operates like an extension of our team. They know our science, anticipate our needs, and deliver with speed and clarity,” said Ben Scruggs, PhD, Altis Biosystems CEO and an early Antheros client.

“We have trusted Sabrina and her team with Nuvig’s patent portfolio since our inception. They have helped us build a science-forward IP strategy that keeps pace with our science and positions us for what’s ahead. We look forward to continuing to work with the Antheros team for Nuvig’s IP needs,” said Pamela Conley, PhD, Nuvig Therapeutics Co-Founder and CSO and early Antheros client.

“The Antheros team brings exceptional expertise and unwavering advocacy that has elevated every one of my ventures,” said Shirin Towfigh, MD, FACS, FEBS-AWS, Hexagon Health CEO. “Their collaborative leadership and strategic insight support my success, and I am honored to continue working with them.”

Recognized in the Chambers Spotlight 2026 California Guide for exceptional expertise in IP, Antheros currently serves more than 30 clients across the U.S. and internationally. The firm offers subscription-based, flat-fee, and blended hourly pricing designed to scale with its clients.
