Shareholders Andrew Freyer, Benno Guggenheimer, Craig Hemenway and Paul Keller have been named in the 2026 Intellectual Asset Management (IAM) Patent 1000 rankings. In addition, Brownstein was recognized by IAM in the patent prosecution and intellectual property transactions categories in Colorado.

Freyer has been recognized in IAM’s prosecution category since 2023. He advises technology-driven clients to build and defend international patent strategies aligned with business, marketing and investment objectives, supplementing his legal counsel with deep technical expertise in full-stack software development, electrical engineering, artificial intelligence and data analytics. A client described him as “an essential consultant, guide and resource,” in this year’s IAM commentary.

Guggenheimer has been ranked in IAM’s prosecution category since 2020. With more than 15 years of experience in patent law, he represents some of the most recognizable names in Silicon Valley and the tech industry at large. He “works closely with clients to build and maintain commercially relevant patent portfolios and brings an engineering background to bear for Fortune 500 companies,” according to this year’s IAM commentary.

Hemenway, the firm’s lead patent attorney for high-tech matters and co-chair of its Intellectual Property Department, has been recognized by IAM since 2013 for both prosecution and transactions. He represents some of the largest technology companies in the world as well as several unicorn startups. IAM notes that he is a “long-standing advisor who operates at the intersection of technology and business, developing creative IP strategies that help technology clients achieve marketplace prominence.”

Keller has been ranked in IAM’s litigation category since 2022. He successfully litigates intellectual property disputes in federal and state courts in a range of jurisdictions. A recognized leader in the field, he also has extensive experience with alternative dispute resolution, including arbitration and mediation. He advises clients on a wide spectrum of technologies (from AI deployment in the life science space to specialty chemicals in the mining industry) through bespoke strategies that meet the particular legal and business needs of the client.
