GRT, Inc. has developed proprietary process chemistry that converts methane to gasoline or other hydrocarbon fuels and chemicals. The GRT process is highly flexible and can be applied to make a wide variety of high volume chemicals and liquid fuels including olefins, aromatics, and high octane gasoline blend stocks. Unlike current technologies (Fischer-Tropsch chemistry and thermal cracking), GRT’s technology does not require high temperatures or pressures to create the gas to liquids reactions, thus providing significant savings in capital costs and operating expenses. 

GRT has licensed certain of its key technologies to Marathon Oil Corporation.


ImaginAb facilitates the promise of personalized medicine through creation of companion diagnostics for patient stratification and targeted molecular therapy. ImaginAb’s technology enables antibodies to be re-engineered into smaller proteins (fragments) with rapid kinetics suitable for diagnostic imaging, while maintaining target biospecificity. In this way true companion in vivo diagnostics can be developed that enable target expression to be profiled in tissues in a non-invasive, whole-body manner.

Intarcia is developing innovative therapies utilizing its Medici Drug Delivery System™ that can transform the prevention and management of serious chronic diseases by optimizing the efficacy, continuous administration and tolerability of drug therapies. The Medici Drug Delivery System™ is a proprietary subcutaneous delivery system comprised of: a technology that stabilizes proteins, peptides, antibody fragments, and other highly potent small molecules at or above human body temperatures for three years or more; a matchstick-sized osmotic pump that is placed just under the skin to deliver a continuous and consistent flow of medication; and placement technology. Intarcia is currently using the Medici Drug Delivery System™ to target Type 2 Diabetes.
