Duleeka Nimantha Bandara RANATUNGA 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).

  • Patent number: 11893733
    Abstract: Systems and methods for predicting a patient response to various agents and/or combinations of agents using ex vivo dosing and imaging are disclosed. In one example, a method of determining treatment efficacy includes analyzing a solid cell culture over time, e.g., first and second responses to a solid cell culture to respective treatments may be compared to determine a treatment efficacy of each treatment. Systems and methods for applying the treatments to the cell culture and analyzing the cell culture and efficacy are disclosed.
    Type: Grant
    Filed: October 26, 2021
    Date of Patent: February 6, 2024
    Assignee: OUROTECH, INC.
    Inventors: Duleeka Nimantha Bandara Ranatunga, Eleonora Peerani, Gastón Agustín Primo, Zhi Yuan Lin, Sacha Hu, Aston Martin Crawley
