We are delighted to announce that the new rankings of the leading firms for patent work in over 75 jurisdictions are now available here on ipstars.com. Congratulations to all the firms listed. Please use the navigation bar to view the rankings for the jurisdictions under each region. The 2017 US national rankings can be found under 'Americas'. The 2017 rankings and editorial for firms ranked under 'United States' will be published in May.
It is important to take note of our publication schedule. We have now confirmed and published the 2017 firm rankings for trade mark
and patent, only.
We will publish the 2017 firm rankings for copyright in April. The firm editorials to accompany these new rankings will be published in May and July this year. Until then, the old copyright firm rankings, firm ranking editorial, Trade mark and Patent Stars published in 2016 will remain on this website. We have placed a notice on all the country pages. All the 2017 rankings, firm ranking editorial, Stars lists and more will be published in IP Stars Global Handbooks in May (for Trade mark and Copyright) and July (for Patent). The US edition of IP Stars Handbook will also be available in May. The handbooks will be made available to Managing IP subscribers and at conferences and events we attend this year.
If you have any enquiries about the handbooks please get in touch with the contacts listed below.
Firms are ranked alphabetically in tiers, as highly recommended, or recommended. The total number of firms listed, as well as the number of tiers, varies by jurisdiction. For some smaller countries, we do not divide the rankings into practice areas, and firms here may be listed under "Intellectual Property" or “Patent”. In most larger countries, we have separate rankings for prosecution and contentious work.
The rankings consider all patent-related work including SPCs. Prosecution covers any pre- and post-registration work before the national IP office but in some jurisdictions, such as in Europe, we do take into account work done at the EPO. Contentious includes other legal work, particularly patent disputes, whether or not it is in the court or tribunal. Of course, some firms have been ranked under both categories.
IP Stars rankings are based on extensive research carried out over a six-month period, starting from September each year. Our team of research analysts in London, New York and Hong Kong obtained information from firms and their clients through interviews, emails and online surveys.
Research analysts also conduct desk research for publicly available information as well as a review of existing data we hold on firms. Among the attributes assessed are: strength of the firm’s IP team, workload, outcomes achieved for clients and track record. The research is conducted rigorously and impartially, and there is no cost to participate. Firms cannot vote or pay for their own inclusion, nor can they solicit votes from associates.
These patent rankings are based on information available when the research was concluded in January 2017. Any subsequent developments such as firm name changes will be reflected in this year’s Handbooks or, where appropriate, in real time on this website.
