Welcome to the online edition of the IAM Patent 1000: The World’s Leading Patent Professionals.

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 2023 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.

Alongside the editorial, there are profiles of some of the firms and individuals featured in the IAM Patent 1000 listings. All of those selected for inclusion in the guide were offered the opportunity to publish a profile for a fee. However, inclusion in the rankings and editorial is not linked to this – the research was conducted entirely independently of any commercial considerations. All firms and individuals ranked in the publication are included because the market told us that they should be.

With publication of this edition now complete, our attention will turn to the research process for 2024. If you have any feedback on this year’s findings or wish to participate in our research, please contact Sophie Storrs [email protected]
