Harri Korhonen 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).

  • Polyester anhydride-based biopolymers
    Patent number: 8129478
    Abstract: Biodegradable polymers formed from biodegradable polyester-based prepolymers, to which ring-structured anhydrides which have different hydrophobicities have been connected, and which are either coupled to form linear thermoplastic polyester anhydrides or cross-linked to form network-structured polyester anhydrides. It is possible to adjust widely the degradation rate and mechanism of the polymers and thus they can be used, for example, in the controlled dosing of pharmaceutical ingredients, for tissue technological applications, in surgery and in bioactive composites.
    Type: Grant
    Filed: January 26, 2007
    Date of Patent: March 6, 2012
    Assignee: JVS-Polymers Oy
    Inventors: Jukka Seppälä, Risto Hakala, Harri Korhonen
  • Novel Biodegradable Polymer
    Publication number: 20090176943
    Abstract: The present invention relates to new biodegradable polymers. These polymers comprise biodegradable polyester-based prepolymers, to which ring-structured anhydrides which have different hydrophobicities have been connected, and which are either coupled to form linear thermoplastic polyester anhydrides or cross-linked to form network-structured polyester anhydrides. It is possible to adjust widely the degradation rate and mechanism of the polymers according to the present invention, and thus they can be used, for example, in the controlled dosing of pharmaceutical ingredients, for tissue technological applications, in surgery and in bioactive composites.
