Benchmark Litigation is the only publication on the market to focus exclusively on litigation in the U.S. The guide’s results are the culmination of a six-month research period that allows its researchers to conduct extensive interviews with litigators and their clients to identify the leading litigators. These interviews are conducted to examine the casework handled by the firms and ask sources to offer their professional opinions on litigators practicing within their state or national practice areas.
