Boston, MA, March 20, 2013Thomas C.

“We are very excited to welcome Tom into our growing Commercial Litigation Group.  While Fish is well known for doing more patent litigation than any other firm, we also have a top-notch business litigation practice that handles high profile, make-or-break your company litigation.  Bringing on a significant lateral hire like Tom, who is so highly regarded, will be tremendously valuable to our clients and our team,” said Ann Cathcart Chaplin, Litigation Practice Group Leader at Fish.  

In 2009, Frongillo obtained an acquittal of a senior executive of W.R. Grace in a landmark three-month criminal jury trial, United States v. W.R.
