Sode Koji 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).

  • Patent number: 9284534
    Abstract: Compositions, devices, kits and methods are disclosed for assaying cholesterol with a cholesterol oxidase mutant that has been modified at an amino acid residue involved in the active site. The cholesterol oxidase mutant has reduced oxidase activity while substantially maintaining its dehydrogenase activity.
    Type: Grant
    Filed: February 24, 2014
    Date of Patent: March 15, 2016
    Assignees: Ultizymer International, Ltd., Roche Diabetes Care, Inc.
    Inventors: Katsuhiro Kojima, Kazushige Mori, Sode Koji
  • Patent number: 8999140
    Abstract: Compositions, devices, kits and methods are disclosed for assaying glucose with a glucose oxidase mutant that has been modified at an amino acid residue involved in the active site. The glucose oxidase mutant has reduced oxidase activity while substantially maintaining its dehydrogenase activity.
    Type: Grant
    Filed: February 24, 2014
    Date of Patent: April 7, 2015
    Assignees: Roche Diagnostics Operations, Inc., Ultizyme International, Ltd.
    Inventors: Katsuhiro Kojima, Kazushige Mori, Sode Koji
  • Patent number: 8962271
    Abstract: In one form, a fructosyl peptidyl oxidase derived from a budding yeast Phaeosphaeria nodorum for assaying a glycated protein in a sample is provided. The fructosyl peptidyl oxidase has higher activity toward fructosyl valine as well as fructosyl valyl histidine, and may be useful in assaying HbA1c with higher sensitivity and specificity. Still, other forms include unique methods, techniques, systems and devices involving a fructosyl peptidyl oxidase.
