Paul Forshey 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).

  • Publication number: 20060241287
    Abstract: Methods for using ionic liquids to extract and separate a biopolymer from a biomass containing the biopolymer are disclosed. Methods for dissolving a biopolymer in an ionic liquid are also disclosed. A recovery solvent is used to reduce the solubility of the biopolymer in the ionic liquid and conventional separation techniques are used to recover the biopolymer. Biopolymers encompassed by this invention include chitin, chitosan, elastin, collagen, keratin and polyhydroxyalkanoate.

  • Publication number: 20050076809
    Abstract: Non-thermoplastic starch fibers having no melting point and having apparent peak wet tensile stress greater than about 0.2 MegaPascals (MPa). The fibers can be manufactured from a composition comprising a modified starch and a cross-linking agent. The composition can have a shear viscosity from about 1 Pascal.Seconds to about 80 Pascal.Seconds and an apparent extensional viscosity in the range of from about 150 Pascal.Seconds to about 13,000 Pascal.Seconds. The composition can comprise from about 50% to about 75% by weight of a modified starch; from about 0.1% to about 10% by weight of an aldehyde cross-linking agent; and from about 25% to about 50% by weight of water. Prior to cross-linking, the modified starch can have a weight average molecular weight greater than about 100,000 g/mol.
