Patrick D. Ertel, (1947 - 2015) 

It is with great sadness that we announce the loss of our friend, mentor, and former partner, Patrick D. Ertel. Pat came to the firm in 1994, and his tenure included extended service on the firm's Executive Committee. Pat was an outstanding advocate on behalf of clients of all sizes, and he was instrumental in training and mentoring a new generation of intellectual property attorneys. He was also an avid sailor and a devout Notre Dame alum. Pat was uniformly respected and exceedingly well-liked. He will be deeply missed.
