Benjamin Rock 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).

  • HIGH STRENGTH CERAMICS WITH NOVEL FRACTURE MODE
    Publication number: 20240043342
    Abstract: The present invention provides a method for making a high strength, small grain size ceramic having a transgranular fracture mode by rapid densification of a green body and subsequent cooling of the densified ceramic. The ceramic may include dislocations, defects, dopants, and/or secondary phases that are formed as a result of the process and resulting in stress fields capable of redirecting or arresting cracks within the material. This ceramic can maintain transparency from ultraviolet to mid-wave infrared.
    Type: Application
    Filed: October 17, 2023
    Publication date: February 8, 2024
    Inventors: Michael Hunt, Guillermo R. Villalobos, Benjamin Rock, Shyam S. Bayya, Woohong Kim, Ishwar D. Aggarwal, Bryan Sadowski, Jasbinder S. Sanghera
