In this role, we are coordinating and executing strategy, and successfully defending the NCAA in courts across the country, including in California, Indiana, Oregon, Hawaii and Washington, D.C. In the first-ever concussion/CTE action against the NCAA to go to trial, we won a complete defense verdict where the Plaintiff alleged the NCAA failed to protect against known risks in football. This was a nationally recognized victory, including "defense verdict of the year" by the Courtroom View Network. Orrick also obtained a complete defense verdict for the NCAA after a four-week jury trial in which the Plaintiff was seeking $125 million in damages for alleged injuries resulting from a football workout. And, in fewer than ten months, we won a third total defense verdict on behalf of the NCAA in another concussion/CTE case, where the Plaintiff alleged the NCAA was responsible for an award-winning quarterback's unfortunate death.

In another significant win, the Orrick team convinced a federal judge to dismiss with prejudice a consumer class action alleging that J&J misled consumers in connection with its marketing of talc products. Most recently, Orrick beat back claims for millions in damages against Johnson & Johnson subsidiary Ethicon alleging that its transvaginal mesh device had a design defect and that warnings about the device were inadequate.
