For 13 years, a small medical device company named Lexion Medical has relied on Dallas attorney David Wille to protect its intellectual property rights. And after building a case that a competitor’s false statements caused Lexion’s sales to tank, Wille persuaded a Delaware jury to award $12.2 million in damages in favor of his client.

Lexion sold a device that delivers heat and humidified carbon dioxide into the abdomen, causing it to expand during laparoscopic surgery, which offers increased health and safety benefits, Lexion has said. Lexion’s competitor, SurgiQuest, sold another device, called the AirSeal system, which uses different technology to serve the same function during laparoscopic surgery.
