Patents by Inventor Patrick Parvis Zarrinkar

Patrick Parvis Zarrinkar 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: 9267165
    Abstract: The invention provides methods for determining the interactions between phage-displayed proteins and test molecules. The phage-displayed proteins are contacted with a reference moiety in the presence and absence of a test molecule; the behavior of the phage-displayed proteins as a function of concentration of the test molecule permits calculation of the binding affinity of the phage-displayed protein for the test molecule.
    Type: Grant
    Filed: August 23, 2007
    Date of Patent: February 23, 2016
    Assignee: DiscoveRx Corporation
    Inventors: David J. Lockhart, Patrick Parvis Zarrinkar, Daniel Kelly Treiber
  • Patent number: 7897381
    Abstract: The present invention provides an advance in phage display technology by permitting the uncoupling of the propagation of phages containing inserted sequences encoding heterologous polypeptides from the expression of said polypeptides. The invention provides phage constructs and methods for their use to permit phage coat protein expression, and thus phage propagation, in the absence of display of heterologous polypeptides, which may be expressed as a fusion with said coat protein in a regulated manner.
    Type: Grant
    Filed: October 31, 2007
    Date of Patent: March 1, 2011
    Assignee: Ambit Biosciences Corporation
    Inventors: Pietro Ciceri, Patrick Parvis Zarrinkar, Daniel Kelly Treiber, David J. Lockhart

  • Publication number: 20080176248
    Abstract: The invention provides an affinity filter for the binding of phage-displayed proteins to dissolved target molecules. The phage-displayed proteins are contacted with immobilized target in the presence and absence of dissolved target; the behavior of the phage-displayed proteins as a function of concentration of dissolved target permits approximation of the affinity of the phage-displayed protein for target. The invention also provides a method to screen large numbers of compounds for their ability to compete with a compound known to bind a phage-displayed protein.
