Yuejuan Li 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).

  • Group of nucleic acid fragments for prevention of HIV infection or AIDS and the usage thereof
    Patent number: 8779113
    Abstract: The invention provides a group of nucleic acid fragments, shown in the sequence listing, for prevention of HIV infection or AIDS and the usage thereof. In the invention, a series of RNA fragments, which are highly homogenous to all the published HIV gene sequences, were obtained by homology compare. The double-stranded RNA (dsRNA) derived from these fragments can effectively inhibit the expression of the HIV genes. The RNA transcribed by plasmid, also can suppress the expression of the HIV in the cell. After the adenovirus or associated virus which carry DNA corresponding above RNA infect the cell, the transcription dsRNA can inhibit the expression of the HIV genes.
    Type: Grant
