Welcome to the 2022 edition of IP STARS.

Please read the information on this page carefully to understand what we have published and what to expect from us in the coming weeks and months.

Following the release of our firm rankings for general IP work (see here), we are delighted to announce the publication of our firm rankings for patent work in more than 50 jurisdictions. Some of the rankings were first revealed in the summer edition of Managing IP's digital magazine.

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 2022 firm rankings).

In FranceGermany and the UK (England), 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.

Congratulations to all the firms ranked this year.

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, leading 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, email, and online surveys.


Firm rankings

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 have about firms and their practitioners. The aspects assessed for the firm rankings include expertise, workload, market reputation and record, outcomes achieved for clients, and unique strengths in each 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. For most jurisdictions, the trade mark and patent rankings are split into prosecution and contentious work.

The prosecution ranking takes account of pre- and post-registration work, including office proceedings and portfolio management advice. The contentious ranking covers all related disputes and enforcement work in and outside the courts (please note that the contentious ranking does not include IP office disputes). Read about our methodology and practice areas here.

The 2022 firm rankings are based on information available at the time the research was completed (February 2022). Except for firm name changes, any subsequent developments or information that could influence our rankings will be considered during the research for the 2023 edition of IP STARS, which starts in September 2022.

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. Managing IP does not recommend or endorse any firm for IP work. Please read the terms of use concerning our content here.

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 can pay to be included or to influence the results.

IP STARS is not a directory of all firms and individuals offering IP services. There are firms and practitioners that we have not recognised even though we have research data about them. Participation in our research does not guarantee ranking. The rankings are subject to change each year.
