The IP survey consists of rankings of the leading firms practising intellectual property in each country, presented in tiers. The total number of firms listed in each jurisdiction varies according to the size of the market. The survey is not an exhaustive list of every firm in each jurisdiction; even firms listed in the lower tiers have been recommended by a number of practitioners and deserve congratulations on their inclusion.
The third part of the survey, covering copyright work, will be published in the April issue. Patents appeared in February.
How the results are compiled
A team of researchers based in London, Hong Kong and New York contacted firms in more than 80 jurisdictions to ask them for information and feedback on the rankings. Client feedback was also considered. Based on this research, firms are ranked in tiers in each jurisdiction. In most jurisdictions, there are separate tables for prosecution and contentious work.
Prosecution work includes filing of patents and associated work in that jurisdiction, including filing for overseas clients. Contentious work includes all other legal work, such as enforcement and licensing. Firms that handle both prosecution and contentious work are eligible to appear in both tables.
The tiers reflect the perception of the leading firms in each market, with the top tier listing those firms regarded as having the strongest practices in each category. Within each tier, firms are listed alphabetically.
No one outside of Managing IP has seen the rankings before publication. No firm can vote for its own inclusion, or recommend an associated or sister firm in another jurisdiction. The rankings reflect the state of the market when the research was conducted, between September 2010 and January 2011. Managing IP itself does not recommend or endorse any particular firms.
