D. Tiller Law PLLC focuses on intellectual property and technology. We provide legal and technical counsel as an advocate and as a neutral. Our practice includes issues related to patents, trademarks, copyrights, trade secrets, and contracts.

Our founder has always been fascinated with applications of technology. This passion resulted in a master’s degree in physics. His graduate school research focused on experimental nuclear physics, which included designing sensors and support electronics as well as interpretive algorithms. 

He later worked as a field engineer in the oil industry from 1995 to 2000. During this time, he used high-technology instruments to determine geophysical properties of wellbore environments.

From 2000 to 2007, Don Tiller worked in research and development (R&D) as a research scientist and project manager, focusing on creating, developing, and acquiring nuclear-physics-based technology. As the result of his work, Don is the named inventor on five U.S. patents in this area.
