Jingen Zhang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Functional fluid compositions containing epoxide acid scavengers
    Patent number: 7018559
    Abstract: A phosphate ester-based functional fluid composition that generates reduced levels of carboxylic acid during use by incorporating at least one acid scavenger selected from the epoxides of the invention. The phosphate ester-based functional fluids are particularly useful as hydraulic fluids.
    Type: Grant
    Filed: May 8, 2001
    Date of Patent: March 28, 2006
    Assignee: Solutia Inc.
