Going into trial last month defending former J.P. Morgan Securities LLC analyst Ashish Aggarwal on insider trading charges, Goodwin Procter partners Grant Fondo and Derek Cohen had a couple of things going for them.

Although Aggarwal was accused of providing tips about upcoming acquisitions he learned about in his job, the Goodwin pair had won a ruling from U.S District Judge Terry Hatter Jr. severing Aggarwal’s case from codefendants he allegedly tipped off who made more than $600,000 profit trading in complex securities trades prior to the announcement of the deals.
