Patents by Inventor John L Kulp

John L Kulp 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).

  • Methods for preparing linked peptide rings and peptide nanotubes obtained thereby
    Patent number: 8975368
    Abstract: Peptide nanotube polymers and methods of making such are disclosed. The peptide nanotube polymers are comprised of alternating monomers of the first peptide ring and monomers of the second peptide ring covalently bonded to one another via a linker, and can be functionalized. The described peptide nanotube polymers can enjoy the combined properties of healing and toughness, self-reporting, and tunability and actuation.
    Type: Grant
    Filed: August 12, 2010
    Date of Patent: March 10, 2015
    Assignee: The United States of America, as represented by the Secretary of the Navy
    Inventors: John L. Kulp, III, Manoj K. Kolel-Veetil, Thomas D. Clark
  • Beta helical peptide structures stable in aqueous and non-aqueous media
    Patent number: 8247533
    Abstract: Disclosed are peptide structures that are stable in aqueous and non-aqueous media where a first linear peptide chain comprising alternating D,L- or L,D-amino acids having an N and C termini is joined by at least one turn region to a second linear peptide chain comprising alternating D,L- or L,D-amino acids having an N and C termini. The peptide chains can be joined at the C terminus of one of the linear peptide chains with an N terminus of the other linear peptide chain, a C terminus of one of the linear peptide chains with a C terminus of the other linear peptide chain, or an N terminus of one of the linear peptide chains with an N terminus of the other linear peptide chain.
