Eric T. Werlinger concentrates his practice on appellate litigation, securities litigation and enforcement, white collar criminal defense, and internal investigations. He has experience representing clients in civil and criminal matters at every level of litigation, including before the US Supreme Court.

In his years of experience as an appellate litigator, Eric has authored numerous briefs and dispositive motions in a variety of matters, including False Claims Act suits, Title VII litigation, patent infringement suits and contractual disputes. Among his notable cases, Eric represented a group of criminal law professors before the Supreme Court as amici curiae in a white collar matter arising under the Sarbanes-Oxley Act. He also served as counsel to a large government vendor in a multibillion-dollar suit under the False Claims Act, in which he assisted his client to a complete victory at both the trial and appellate levels. In state court, Eric successfully represented a major real estate investor in a complex, fast-moving contractual dispute, obtaining dismissal with prejudice in a month's time.

He recently represented a major pharmaceutical company in a federal court of appeals, securing final dismissal of a putative class action under the Securities Exchange Act of 1934. Likewise, Eric has helped a variety of clients navigate dispositive briefing under the Private Securities Litigation Reform Act, and has counseled both entities and individuals with responses to SEC and US Department of Justice investigative requests.
