Firms


On this page, you can review examples of work done by some of the leading big law firms. The cases we’ve chosen exemplify the type of high-stakes legal work that powers the profits of big firms. For each case, we’ve provided a brief summary of the litigation, and, where possible, a sample from the work product produced by the firm. For students, that means you can read the very type of brief you might be asked to help write as a first-year associate.

The information in these cases comes from public sources that we’ve linked to, including public court filings, news articles, and the websites of the firms themselves. Note that the information on this website is by no means comprehensive; we’re just aiming to give readers a sense of the type of work that powers big law.
