Claiming it’s one of the largest recoveries in a shareholder oppression lawsuit, two Houston civil litigators Thursday announced a $300 million settlement in a dispute between shareholders and a biotechnology company.

In a case that shows how important strategy is to legal victories, Jim Southwick and Alex Kaplan, two partners in Susman Godfrey in Houston, said that months of pre-litigation research and preparation of the legal theory in their case is what secured the win.
