Patents by Inventor Bhishamjit S. Chera

Bhishamjit S. Chera 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).

  • Publication number: 20240110253
    Abstract: Disclosed herein are DNA amplification methods for quantifying DNA fragments of a target DNA in a sample by size. This can be used, for example, to detect tumor-derived viral DNA in blood sample and distinguish it from larger viral DNA from non-tumor sources. In particular, disclosed herein are methods of detecting, monitoring or treating a human papilloma virus (HPV)-associated malignancy in a subject that involves detecting a presence or absence of at least one circulating tumor-derived HPV DNA in a sample from the subject. Kits for accomplishing the same are also provided.
    Type: Application
    Filed: September 6, 2023
    Publication date: April 4, 2024
    Inventors: Gaorav Gupta, Bhishamjit S. Chera, Sunil Kumar
  • Patent number: 11913080
    Abstract: The present disclosure provides methods and compositions of modified oligonucleotide primer and probe combinations, structurally modified with locked nucleic acids, quenchers, and dyes, effective to detect tumor-derived Human Papilloma Virus (HPV) and tumor-derived Epstein-Barr virus (EBV) and, especially, to distinguish viral DNA derived from tumors from viral DNA derived from infectious viral particles.
