Welcome to the 2021 edition of IP STARS.
Managing IP is delighted to publish the 2021 firm rankings for patent work in more than 50 jurisdictions. Some of the firms featured this year are widely regarded in the market as the best firms for patent work.
To check if a firm has been ranked this year for patent work, enter the firm’s name in the search bar or use the regional navigation menu above to select the jurisdiction (click on 'Rankings' to see the 2021 firm rankings).
In Germany, we have a special rankings table that recognises patent attorneys for their litigation work. For the US, we have patent rankings for states such as California as well as national rankings, including PTAB litigation and Life Sciences IP (see the United States (National) page).

Any research information not considered or used for this year’s edition will be used for the 2022 edition. We will start the research for the 2022 edition of the IP STARS rankings and Managing IP Awards in September 2021. The submission deadline is October 31.
Managing IP published its first legal directory in 1994 and rebranded it in 2013 as IP STARS. The publication quickly established itself as the leading specialist guide to IP law firms and practitioners worldwide. The research for IP STARS covers a variety of IP practice areas and more than 70 jurisdictions, making it the most comprehensive and widely respected guide in the IP profession.
The research for these rankings was conducted rigorously and impartially by our team of research analysts in London, New York and Hong Kong. Each year we request information from thousands of firms, IP practitioners and their clients through interviews, email and online surveys.
Before compiling the rankings, our analysts also conducted their own independent research, including an analysis of publicly available information (such as court or IP office data) and existing data we hold on firms.
The aspects assessed for the firm rankings include expertise, workload, market reputation/record, outcomes achieved for clients, and unique strengths in a given practice area. Judgements about which firms to include in the rankings, and which tier and practice area they should be in, take account of all this information.
Firms are ranked alphabetically in tiers, or as highly recommended or recommended. The total number of firms listed varies from jurisdiction to jurisdiction. The rankings are split into prosecution and contentious work in most jurisdictions and in others we consolidated the practice areas.
The prosecution ranking takes account of pre and post-registration work including office proceedings and portfolio management advice. The contentious ranking covers patent-related disputes work (in and outside the courts). Where appropriate, some firms were ranked for both practice areas. We also have special patent rankings in Germany and the United States.
These rankings are based on information available at the time the research was completed (February 2021). Except for firm name changes, any subsequent developments or information that could influence our rankings will be considered during the research for the 2022 edition of IP STARS, which starts in September 2021. However, Managing IP reserves the right to remove a firm or individual from our website at any time.
The IP STARS rankings are not influenced by any commercial relationship, including advertising, with Managing IP or IP STARS. There is no fee to pay to participate in our research. No firm or practitioner can pay to be ranked. Participation in our research does not guarantee ranking. The rankings are subject to change each year.
