YES Technologies, also doing business as Yellowstone Environmental Science Inc (YES), was founded for the creation, development and commercialization products for enhancing public health and protecting the environment. YES owns rights in 22 U.S. patents, four foreign patents, 6 U.S. patent applications, and 6 pending patent applications in Japan, Australia, Germany, Canada and Korea. These issued patents and patent applications disclose pioneering inventions in the fields of expert support systems, flow metering, pressure sensing, in-situ pipeline rehabilitation, environmental biotechnology (biohydrometallurgy and hazardous waste bioremediation) and various child-resistant products. YES was retained to assist the licensee of the firm's flow metering technology to design the first commercial version of the DataGatorTM Flow Meter System for wastewater flow metering applications. This product has been manufactured in the U.S. and sold worldwide. The firms granted a major U.S. pharmaceutical company a non-exclusive worldwide license to practice YES's WiseCapTM Elder Accessible Child-Resistant Packaging Technology for prescription drug packaging. That first licensee agreed to distribute a minimum of 10,000,000 elder-accessible packages each year. Yes have also successfully concluded the sale of rights to the firm's in situ pipeline rehabilitation process to a U.S. trenchless technology company.
