Patents by Inventor Kyunghoon Jeong

Kyunghoon Jeong 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: 9765376
    Abstract: The present invention provides a nucleic acid sequence amplification method and apparatuses thereof that are simple in the design and easy to miniaturize and integrate into complex apparatuses, with capability of using DNA polymerases that are not thermostable. In the present invention, a plurality of heat sources are combined to supply or remove heat from specific regions of the sample such that a specific spatial temperature distribution is maintained inside the sample by locating a relatively high temperature region lower in height than a relatively low temperature region.
    Type: Grant
    Filed: October 17, 2013
    Date of Patent: September 19, 2017

  • Patent number: 9346055
    Abstract: The present invention generally relates to methods and apparatuses for amplifying nucleic acid sequences using immobilized DNA polymerase. More particularly, it relates to methods and apparatuses useful for amplifying target nucleic acid sequences by forming a plurality of reaction regions in which polymerase chain reaction (PCR) can occur, positioning immobilized DNA polymerase in a specific reaction region, and circulating DNA through the reaction regions. The present invention provides those methods and apparatuses that allow simple separation and recovery of the DNA polymerase after the amplification, that can be operated not only with thermostable DNA polymerases but also with non-thermostable DNA polymerases, and that are simpler in their designs and processes so that they can be readily integrated into complex devices such as Lab-on-a-chip.
