Anna Maria Hedlund 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).

  • Elimination of N-glycolylneuraminic acid from animal products for human use
    Patent number: 8828652
    Abstract: The application is in the field of transgenic (non-human) organisms, sialic acid chemistry, metabolism and antigenicity. More particularly, the invention is related to a method to produce Neu5Gc-free animals and products therefrom comprising disrupting the CMAH gene and thereby reducing or eliminating Neu5Gc from biological material of non-humans.
    Type: Grant
    Filed: August 13, 2013
    Date of Patent: September 9, 2014
    Assignee: The Regents of the University of California
    Inventors: Ajit Varki, Anna Maria Hedlund, Dzung Nguyen
