Intellectual Property
Our core technologies consist of know-how technologies to improve the quality of finished and heavy oil products, and three utility model patents related to biodiesel production.
Since 2006, we filed the 11 patent applications listed below with the State Intellectual Property Office of China (SIPO), all of which are related to our first generation biodiesel production.
The SIPO has granted the following four applications for utility model patents (click the application number to view the certificate):
- Application No. 200820221671.0 for a new gas-liquid distributor of material filling tower
- Application No. 200620137855.X for a new reaction vessel for preparing biodiesel and composite diesel
- Application No. 200620137854.5 for a new reaction equipment for preparing biodiesel
- Application No. 200820028705.4 for an anti-corrosion device for biodiesel esterification reaction
We have six invention patent applications that are pending approval (click the application number to view the certificate):
- Application No. 200610152508.9 for a biodiesel processing technique
- Application No. 200610152506.X for a new composite catalyst for preparing biodiesel
- Application No. 200610152507.4 for a new technology for processing biodiesel with catalyst or splitting decomposition in liquid or gas face
- Application No. 200810017853.0 for a new technique for disposing biodiesel esterification reaction equipment with inert metal lead
- Application No. 200810017849.4 for a new method for preparing biodiesel with supercritical technology
- Application No. 20081001784.8 for a new technique for producing biodiesel and its byproducts with molecular distillation
Additionally, we have two patent applications pending approval for our second generation technology (click the application number to view the certificate):
- Application No. 201010294330.8 for the water gas shift equipment in biodiesel production process
- Application No. 201010294327.6 for the highly efficient synthesis of biodiesel fuel
We have patent protection for each of our utility model patents for a period of ten years from the date of filing. If our invention patents are approved, they will be valid for a period of twenty years from the date of filing. Upon expiration, the renewal process requires us to re-apply for patent protection.
We developed technologies for the production of biodiesel jointly with the Xi’an Petroleum University and Northwest Agriculture and Forestry University. We developed our proprietary technology for the production of biodiesel jointly with Tsinghua University and we were permitted to use this technology under a contract dated September 4, 2006. We have the right to use the oil mixing technology developed by Xi’an Petroleum University for ten years under a contract entered into on December 18, 2005.
