Managing IP describes its methodology as follows:
Each year, Managing IP's research analysts in London, New York and Hong Kong obtain information from thousands of firms, IP practitioners and their clients through interviews, emails and online surveys. Before compiling the rankings, our research analysts also conduct their own independent research, including an analysis of publicly available information (such as court or IP office data) and the existing data we hold on firms. All our rankings are based on the information available at the time the research was completed. Except for firm name changes, any subsequent developments or information that can influence our ranking decisions will be considered during the research for the next edition. However, Managing IP reserves the right to remove a firm or individual from our website at any time. The research is conducted rigorously and impartially. There is no fee to pay to participate in the research. More information about its methodology is available here.
