Philip Shepherd 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: 10736335
    Abstract: Dried fruit powders are used as a replacement for current bulking agents used in chewing gum, such as polyols or sucrose, thereby providing healthier chewing gum options to consumers with real fruit taste.
    Type: Grant
    Filed: November 15, 2012
    Date of Patent: August 11, 2020
    Assignee: WM. WRIGLEY JR. COMPANY
    Inventors: Xiaoqun Mo, David R. Phillips, Xiaohu Xia, Philip Shepherd
  • Publication number: 20170238576
    Abstract: A gum base comprises nanoparticles and/or non-uniform microparticles containing at least one crosslinked polymer. Non-uniform microparticles may be in the form of polymer composite microparticles, hollow shell microparticles and/or core-shell microparticles. It has been found that such gum bases exhibit desirable chewing properties similar to conventional gum bases. Cuds formed by chewing gum bases containing crosslinked polymer microparticles are easily removable from environmental surfaces such as concrete, fabrics and flooring materials.

  • Publication number: 20150216200
    Abstract: Chewing gums and chewing gum bases which are cud-forming and chewable at mouth temperature contains a block copolymer having at least two hard crystallizable polymeric blocks and at least one soft polymeric block. At least one hard polymeric block is a hard crystallizable polymeric block has a melting point greater than 20° C. The hard, crystallizable polymeric blocks and the soft blocks each have a degree of polymerization of at least 15 Characteristics of the block copolymers can be selected to produce gum bases and chewing gums having desired properties. In some cases, chewed cuds formed from the gum bases may exhibit improved removability from environmental surfaces to which they may become undesirably attached.

  • Publication number: 20110123672
    Abstract: The present invention provides gum bases and chewing gums, as well as methods of manufacturing the gum bases. More specifically, the gum bases provided herein contain microparticles comprising a crosslinked polymer. The microparticles render a gum cud comprising the gum base more easily removable from surfaces onto which it may become adhered than gum cuds comprising conventional gum bases.
