Patents by Inventor Anne Margaret Tinsley-Bown

Anne Margaret Tinsley-Bown 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).

  • Encapsulation of bioactive agents
    Patent number: 6565777
    Abstract: Bioactive agent is encapsulated in a polymer microparticle in a (water-in-oil)-in-water emulsion-based method, and using a solvent that comprises ethyl acetate. Also described are microparticles comprising low inherent viscosity (i.v.) PLG, some with i.v. less than 0.5 dl/g, and methods for their preparation. DNA release is modified through use of low i.v. PLG. A particle production method for scale-up uses a blender that avoids excessive shear damage to DNA being encapsulated.
    Type: Grant
    Filed: May 29, 2002
    Date of Patent: May 20, 2003
    Assignee: Microbiological Research Authority
    Inventors: Graham Henry Farrar, Anne Margaret Tinsley-Bown, David Hughes Jones
