Matthew STURGEON 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).

  • Photoluminescent iron-doped barium stannate material, security ink composition and security feature thereof
    Patent number: 11352517
    Abstract: The present invention provides photoluminescent iron-doped barium stannate materials absorbing ultraviolet (UV) light and exhibiting strong near-infrared (NIR) luminescence. Such materials exhibit increased integrated photoluminescence intensity in comparison to known BaSnO3 and iron-doped barium stannate materials, and therefore they are particularly useful for the production of photoluminescent security ink compositions and transparent covert security features with improved anti-counterfeiting resistance that can be used for protection of documents and articles against counterfeit and illegal reproduction.
    Type: Grant
    Filed: March 20, 2018
    Date of Patent: June 7, 2022
    Assignee: SICPA HOLDING SA
    Inventors: Scott Haubrich, Pascal Pinceloup, Eden Michele Anthanasee Green, David Anderson, Matthew Sturgeon
