Albert Hee Lum Chow 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).

  • Manufacture of nonelectronic, active-infusion patch and device for transdermal delivery across skin
    Patent number: 10548854
    Abstract: Transdermal patches and devices for delivery of therapeutic drug and/or cosmetic formulations through an intact or porated skin barrier are described. Active-infusion delivers controlled dosing over a period of time to provide long-term efficacy. Methods and devices for preparing active-infusion patches for controlled dose delivery by nonelectronic devices and methods of skin poration that is safe and painless are described.
    Type: Grant
    Filed: September 23, 2013
    Date of Patent: February 4, 2020
    Assignee: The Hong Kong University of Science and Technology
    Inventors: King Lun Yeung, Wai Kit Wong, Siu Ming Kwan, Li Yin Chau, Ho Yee Timothy Poon, Ming Hung Thomas Lee, Albert Hee Lum Chow
  • Engineering of polymer-stabilized nanoparticles for drugs with Log P values below 6 by controlled antisolvent precipitation
    Patent number: 10076496
    Abstract: The present invention provides organic nanoparticles that include a molecule having a Log P value of about 3 or above, an amphiphilic diblock copolymer or a surfactant, and a pharmaceutically-acceptable hydrophilic polymer. The present invention also provides methods of making these nanoparticles, e.g., by flash nanoprecipitation, with control over particle size and surface properties. The methods of the present invention provide a means for co-precipitating a water-insoluble compound with an amphiphilic stabilizer within a few milliseconds. The nanoparticles of the present invention exhibit high drug loading, e.g., 50% w/w, and can be produced with a mean particle size less than 200 nm and with a narrow particle size distribution.
