He is also great at figuring out how to win cases without spending a shed-load of his clients' money." He provides strong leadership to Holland & Knight's national IP group.

Whether he is asserting his client's IP, defending against competitors or fending off Non-Practicing Entities (NPE), Mr. Donoghue blends his deep litigation experience with practical business insight garnered from his in-house experience.
