Chin Jen Ku 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: 20240026459
    Abstract: Disclosed herein are methods for identifying patients with pancreatic cancer and subjects at risk for developing pancreatic cancer, methods for monitoring a patient with an identified pancreatic lesion, methods for evaluating the effectiveness of a treatment used for a patient with pancreatic cancer, and methods for selecting a therapy for treating pancreatic cancer in a particular patient. The invention makes use of hydroxymethylation biomarkers, which in combination with one or more clinical parameters and optionally one or more additional types of biomarkers and/or patient-specific risk factors, exhibit a hydroxymethylation level that correlates with pancreatic cancer. Kits and other methods of use are also provided.

  • Publication number: 20230095582
    Abstract: A method is provided for probabilistically assigning a tissue of origin to a nucleic acid in a sample, e.g., DNA in a cell-free fluid sample obtained from a human subject. A hydroxymethylation profile is generated for the sample DNA and then compared across a reference data set of hydroxymethylation profile vectors, where each hydroxymethylation profile vector identifies the hydroxymethylation profile at a specific reference locus, the tissue-specific gene associated with the reference locus, and the tissue with which the gene and reference locus are associated. A tissue of origin can be probabilistically assigned to the sample nucleic acid using the results of the comparison. Other methods of use are also provided.

  • Publication number: 20210108274
    Abstract: Disclosed herein are methods for identifying patients likely to have pancreatic ductal adenocarcinoma (PDAC) and patients likely to be at risk for developing PDAC. Related methods are also provided that pertain to patient monitoring, treatment evaluation, and an improved multi-cancer test., as are kits that are suitable for carrying out the aforementioned methods. The invention makes use of hydroxymethylation biomarkers, which in combination with one or more clinical parameters and optionally one or more additional types of biomarkers and/or patient-specific risk factors, exhibit a hydroxymethylation level that correlates with the presence of or risk of developing PDAC.

  • Publication number: 20100300311
    Abstract: A screen printing machine includes a platen for supporting a substrate to be printed, a printing screen disposed above the platen, a squeegee to be moved across the printing screen in order to force an ink through the printing screen and onto the substrate, a conveyer device disposed below the platen, and a squeegee actuating device supported on the conveyer device, the squeegee actuating device includes a housing having a chamber for receiving one or more electromagnetic devices each of which include a coil having a compartment for receiving a core, and a magnet disposed above the core and secured to the core and the housing for being actuated by the core to selectively attract the squeegee to press onto the printing screen and to selectively release the squeegee.
