This year, IAM will be conducting in-depth research for the 13th edition of its major unique publication, IAM Patent 1000: The World’s Leading Patent Professionals. The guide will include detailed reviews of firms and individuals engaged in patent prosecution, transactions and patent litigation in over 60 jurisdictions. Research will begin in September 2023.


Any information that you can provide during the research process is likely to improve the chances of members of your firm being listed, as it will complement our own research findings. We would be grateful if you could suggest a couple of time options when a representative(s) from your firm would be available for a 30-minute phone conversation with one of our researchers. All interviews are conducted confidentially, and any comments made will remain strictly non-attributable.

Submissions and client referees

It is helpful if firms submit to us brief overviews of their practice, short biographies of the lawyers involved and summaries of recent work highlights, making sure to clearly mark as confidential any cases/details that are not in the public domain.

In order to enhance the feedback that we gather on your lawyers and attorneys, on the basis of which we draw up our ranking tables, we strongly suggest that you submit to us referees (preferably purchasers of your firm’s services) who may be contacted to provide confidential references on their work.

The IAM Patent 1000 2024 submission form and client referee sheet are available for download. While we recommend that you complete the online form, if you do require a Word version of the form, it is available for download here. Please ensure you also download the client contact sheet here.
