Mari Hakkinen 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).

  • Polypeptides and active fragments of polypeptides having at least one esterase activity
    Patent number: 9783793
    Abstract: The present invention relates to novel polypeptides, or fragments of polypeptides, genes encoding them and means for producing said polypeptides. In detail the invention relates to polypeptides having esterase, suberinase and/or cutinase activity at low pH. This invention relates also to compositions containing the polypeptides and methods of using the polypeptides.

  • Method for improved protein production in filamentous fungi
    Patent number: 9695430
    Abstract: The present invention relates to a method for genetically modifying a filamentous fungus host for improved protein production. The method comprises that a filamentous fungus host is genetically modified to overexpress or to be deficient of specific genes. The invention relates also to the modified hosts. Furthermore, the invention relates to a method for improved production or for producing an improved composition of proteins, such as cellulases, hemicellulases, other proteins involved in the degradation of lignocellulosic material, or other proteins, in a filamentous fungus host.
