Qualifications: U.S. Patent Agent
PRACTICE AREAS AND INDUSTRIES SERVED
Dr. Schaefer assists with the drafting and prosecution of foreign and domestic patents in the fields of chemistry, materials, science, oilfield technologies, and nanotechnology.
Dr. Schaefer is skilled in the drafting and prosecution of patents relating to specialized drilling fluids, downhole tools (e.g., drill bits, cutting elements, etc.) and their implementation in the field, among other oilfield technologies. Dr. Schaefer’s technical background lies primarily in the synthesis, characterization, and utilization of nanoparticles for complex problems. Dr. Schaefer received his Ph.D. in Chemistry from The Pennsylvania State University, where his graduate dissertation detailed the low-temperature chemical synthesis of intermetallic, carbide, borocarbide, and carbonaceous nanoparticles. He then worked as a Postdoctoral Research Associate in the Chemical Engineering Department at Rice University where he aided in the development of surfactant bi-layer coated carbon based nano-reporters for in-situ data collection and/or enhanced oil recovery in oilfields.
