Armstrong Teasdale’s Complex Commercial Litigation practice is comprised of elite, experienced trial lawyers with uncommon insight into how to navigate and litigate increasingly complex, high-stakes disputes.

Our team has tried hundreds of cases for both plaintiffs and defendants in federal and state courts, as well as regulatory bodies all over the country. Our experience spans every significant category of commercial litigation, including breach of contract, business torts, RICO, consumer fraud, regulatory violations, antitrust, shareholder derivative actions, breach of fiduciary duty, trade secret misappropriation, Lanham Act violations, copyright infringement, unfair competition, class actions and mass torts.

Companies routinely trust Armstrong Teasdale’s lawyers with disputes of such consequence; they could impact their viability or even an entire industry. Our lawyers have managed complex matters in over 30 states, are familiar with appellate and trial courts across the country, and have the breadth and depth to help our clients achieve the best possible outcomes. Our clients have called us “fantastic litigators” and “zealous advocates” in Chambers USA: America's Leading Lawyers in Business, where several of our trial lawyers are ranked for Commercial Litigation.

Our sole, driving purpose when representing a client is to quickly identify and devise a strategy to achieve the client’s goals. In doing so, our lawyers strive to understand all aspects of the dispute and how those issues affect the client’s business. Our lawyers’ extensive trial experience uniquely positions Armstrong Teasdale to nimbly implement virtually any strategy the client desires, from a quick and effective resolution to full-blown trial and appeal, if necessary. Based on their experience, our lawyers possess the vision and understanding of the impact decisions made today will have at trial, several months or years later. With this demonstrated trial experience and forward-thinking vision, our clients receive the most effective representation.

As a firm, we possess the tools and talent to achieve favorable results for clients in the courtroom. Our in-house litigation support department, Lawgical Choice, allows our lawyers to rapidly and proficiently gather, organize, identify and produce gigabytes of our client’s data in a cost-effective manner. And because we are based in smaller, less expensive metropolitan centers, our rates are often substantially less than those of traditional, large litigation practices, which not only allows our clients to save millions of dollars in legal fees, but also empowers them with the flexibility to litigate their disputes so as to reach the optimal result, rather than having to sacrifice potential advantage because realizing those advantages may be cost prohibitive under the rate structures of other firms.

Armstrong Teasdale attorneys work across disciplines to leverage our experience for each client and situation. We also work across a variety of industries, including financial services and banking, technology and manufacturing, consumer products, agribusiness and food, and health care and life sciences.
