Overview:  Mr. Thornburg is a Registered Patent Attorney with extensive experience in the areas of patent, trademark, trade dress, trade secret, and unfair competition related litigation, enforcement and defense. Robert manages the Miami office of Allen Dyer Doppelt Milbrath & Gilchrist P.A., Florida’s largest intellectual property law firm having six strategic offices throughout the State.

Robert’s law office provides the best of both worlds, the strength and experience of a large multi-faceted intellectual property law firm, with the hands on attention, cost-effectiveness and personalized touch of a smaller law practice.

Intellectual Property Transactions Experience: Mr. Thornburg represents an impressive roster of Florida and South American clients in the areas of patent and trademark prosecution, domain name disputes, and electronic discovery counseling. His experience in patent prosecution includes CPAP respiratory interfaces, high efficiency cogeneration HVAC systems, medical devices, consumer products, security systems, mechanical devices, process systems, telecommunications systems, pharmaceuticals and “green” technologies. Robert is one of the very few attorneys in Florida that has experience in drafting over 100 patent applications, over 200 trademark filings, and litigated over 100 complex intellectual property disputes.

Intellectual Property Litigation Experience: Recent examples of Robert’s intellectual property litigation experience includes:
