Swapnil R. Chhabra 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).

  • Hybrid organic-inorganic system for producing biofuels
    Patent number: 9777300
    Abstract: The present invention provides for a system for converting CO2 and H2 to one or more biologically derived compounds. In some embodiments, the system comprises a host cell comprising one or more nucleic acids encoding genes for a recombinant surface display protein which is capable of tethering an electrocatalyst molecule, such as a cobalt(II) complex supported by tetradentate polypyridyl ligand 2-bis(2-pyridyl)(methoxy)methyl-6-pyridylpyridine (PY4), and enzymes for synthesizing a biologically derived compound, such as an alkane, alcohol, fatty acid, ester, or isoprenoid.
    Type: Grant
    Filed: May 8, 2014
    Date of Patent: October 3, 2017
    Assignee: The Regents of the University of California
    Inventors: Yi-Chun Yeh, Steven W. Singer, Swapnil R. Chhabra, Harry R. Beller, Jana Mueller
  • Glycoside hydrolases having multiple hydrolase activities
    Patent number: 9725749
    Abstract: Glycoside hydrolases having at least two different hydrolytic activities are provided. In one embodiment, an isolated recombinant hydrolase having at least two activities selected from a group including asparagine derivatives, glutamine derivatives, and histidine derivatives is provided. Further, a method of generating free sugars from a mixture comprising asparagine derivatives, glutamine derivatives, and histidine derivatives is provided.
    Type: Grant
    Filed: May 1, 2012
    Date of Patent: August 8, 2017
    Assignees: The Regents of the University of California, Sandia Corporation
    Inventors: Zhiwei Chen, Gregory D. Friedland, Swapnil R. Chhabra, Dylan C. Chivian, Blake A. Simmons
