Today, we released the latest firm rankings for the 2023 edition of IP STARS. The rankings are for patent disputes and filing/prosecution work and cover more than 60 jurisdictions.
This is the third set of firm ranking results for this year’s edition of our legal directory. We published the rankings for trademark work in March (see here) and last month we released the rankings for general intellectual property work for jurisdictions without specific practice area rankings (read more here). These firm rankings are based primarily on information available during the research period for this edition (September 2022 – February 2023).
Please see the jurisdictions we cover below or visit ipstars.com to check if a firm has been ranked this year for patent, trademark, or general IP work.
IP STARS is not a directory of all firms and individuals offering IP services. Participation in our research does not guarantee a ranking. Read our research methodology below. If you have any feedback, suggestions, or questions, please contact us here.
Congratulations to all the firms ranked this year.
What to expect next
We have more rankings to announce in the coming weeks and months, and we will therefore continue with our research. Below is a snapshot of the 2023 edition content publication timeline. Any research information not considered or used for this year’s edition will be used for the 2024 edition. We will start the research for the 2024 edition of the IP STARS rankings and Managing IP Awards in September 2023.

About IP STARS rankings
Managing IP published its first legal directory in 1994 and rebranded it in 2013 as IP STARS. The IP STARS guide has expanded over the years and now covers over six IP practice areas and more than 70 jurisdictions, making it the most comprehensive specialist rankings publication for the IP profession.
Research methodology
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, emails, 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 about firms. The aspects assessed for the firm rankings include expertise, workload, market reputation and record, outcomes achieved for clients, and unique strengths in a given practice area. These are considered when deciding which firms to include in the rankings and which tier and practice area they should be in.
Firms are ranked alphabetically in tiers, or as highly recommended or recommended. The total number of firms listed varies from jurisdiction to jurisdiction. For most jurisdictions, the rankings are split into prosecution and disputes work. However, in certain jurisdictions, we evaluated and ranked firms for their intellectual property practice as a whole.
The prosecution ranking takes account of pre- and post-registration work, including office proceedings and portfolio management advice. The disputes ranking covers all patent-related disputes and enforcement work in and outside the courts (please note that the disputes ranking does not include IP office disputes). Read about our methodology and practice areas here.
These rankings are based on information available at the time the research was completed (February 2023). Except for firm name changes, any subsequent developments or information that could influence our rankings will be considered during the research for the 2024 edition of IP STARS, which starts in September 2023.
For the avoidance of doubt, the ranking tables do not suggest or indicate that the expertise or services of the listed firms are limited to the practice area in question, and Managing IP does not recommend or endorse any particular firm for IP work. No firm can pay to be included or to influence the results.
There is no fee to pay to participate in our research, and commercial relationships, including advertising, with Managing IP or IP STARS do not influence the results.
Our rankings are subject to change each year. Click here to learn more about our research.
