Trevor E. Wilantewicz 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).

  • Ion-exchanged glass of high surface compression and shallow depth of layer with high resistance to radial crack formation from vickers indentation
    Patent number: 10611674
    Abstract: Disclosed are alkali aluminosilicate glasses having unexpected resistance to indentation cracking. The glasses obtain this high resistance as a result of a high level of surface compression accompanied by a shallow depth of layer. The advantaged glasses show greater resistance to radial crack formation from Vickers indentation than glasses with the same compressive stress, but higher depths of layer.
    Type: Grant
    Filed: August 31, 2017
    Date of Patent: April 7, 2020
    Assignee: CORNING INCORPORATED
    Inventors: Jonathan David Pesansky, Chandan Kumar Saha, Trevor E Wilantewicz
