The IAM Patent 1000 is commonly regarded as the definitive 'go-to' resource for those seeking to identify world-class, private practice patent expertise as well as leading expert witnesses in the US. As with previous editions, to arrive at the 2026 rankings, IAM undertook an exhaustive qualitative research project to identify outstanding firms and individuals across multiple jurisdictions. When identifying the leading firms, factors such as depth of knowledge, market presence, and the level of work on which they are typically instructed were all taken into account, as well as positive peer and client feedback.
