Last year, activist investors Sidus Investment Management and BLR Partners LP triggered a sweeping leadership change at Acacia Research Corporation. The overhaul of Acacia’s executive leadership is now apparently nearing completion, with a freshly reconstituted board of directors and the recent appointment of Clifford Press (cofounder of the investment company Hyde Park Holdings) as CEO and Alfred Tobia Jr. (cofounder of Sidus Investment Management) as CIO. Meanwhile, Acacia’s board is reportedly working to “advance” the company’s IP business, with the NPE in the midst of somewhat of a litigation revival in the wake of last year’s shake-up.
