IAM Patent 1000,  2015 - 2020
2020: “Diversification has been a recent point of emphasis for Brownstein. Its well-rounded patent group has added variety to its roster of large institutional patrons and is increasingly engaged by Bay Area start-ups at different valuation levels, up to $1 billion. Demonstrating impressive agility, the set is comfortable maneuvering within the guardrails that big companies have in place, while offering flexibility to fledgling entities. All comers, however, enjoy the benefit of creative and commercial solutions."
