About Dennis J.M. Donahue III
Dennis Donahue III is an experienced, highly effective intellectual property attorney, manager, and business advisor, with expertise in all areas of intellectual property law both in corporate and private practice. Clients served include multi-billion dollar international retailer, aerospace manufacturing giant, aerospace subassembly supplier, secure communications start-up company and internet entrepreneurs.

After more than a decade of large firm practice, Donahue says the formation of DD&A allows him to work more closely with smaller inventors and entrepreneurs who may not otherwise have a cost effective way to protect their ideas and grow in a tough economy. Donahue believes it's also time for a more personal, back to basics approach for larger businesses who need their brands and technology to stay protected and competitive, despite shrinking corporate legal budgets.
