Armstrong Teasdale’s Patent practice and six of its attorneys have been recognized among IAM’s 2026 Patent 1000, a ranking of the world’s leading patent professionals. Partners Patrick Brennan, Richard Brophy, Daniel Fitzgerald, Erin Florek, Christopher Goff, and Jim Heinen, Jr. are listed in this year’s rankings, and the firm’s Patent practice area has achieved a Gold ranking in Missouri.
This year’s guide describes Armstrong Teasdale as “professional and competent” with “bright, knowledgeable, talented, conscientious and efficient” lawyers and “a broad bench trusted by Fortune 500 companies, universities, startups and emerging businesses for strategically aligned, technically fluent IP advice.”
Armstrong Teasdale provides patent services to some of the world’s largest companies, managing portfolios containing thousands of patents. The firm’s patent team includes over 50 lawyers and patent agents registered to practice before the U.S. Patent and Trademark Office. The team has filed nearly 15,000 patent applications in the last five years, with more than 3,000 of those originally drafted and filed.
“The fact that our department and these professionals are ranked consistently year over year reflects the ongoing trust our clients put in us to protect their innovations,” said Heinen, leader of the Intellectual Property practice group. “I’m proud of our group’s accomplishments, and I’m glad to see both our department as a whole and these specific individuals recognized. We have a comprehensive patent practice, and each member of the group contributes to our success.”
Considered the “go-to” resource for identifying world-class patent expertise, the Patent 1000 rankings are determined by an extensive research process that includes approximately 900 interviews with attorneys and in-house counsel to identify leading candidates for consideration. Where appropriate, recommendations are presented in gold, silver, and bronze bands reflecting the reputations of teams and professionals relative to their peers.
