As part of its 2026 rankings, IAM states Perkins Coie, "Offers one of the most complete patent practices in the market, combining the scale of a major full-service firm with a notably deep technical bench. Its distinguishing feature is the breadth of its coverage across the patent life cycle: prosecution, litigation, post-grant work, appeals, and transactions are all handled at a high level, with particularly strong capabilities in software, AI, life sciences, and other technology-heavy sectors. That integrated structure gives clients access to strategic advice that is not confined to one stage of the patent process, but instead reflects how portfolios are built, challenged, enforced, and monetized over time.”
