Charles Weidner 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).

  • Staining reagents and other liquids for histological processing of biological specimens and associated technology
    Patent number: 10551395
    Abstract: Processing specimens in an automated histological staining system comprising robotically moving a slide carrier into a stainer of the system, the slide carrier carrying slides which respectively carry the specimens, and the specimens being at least partially embedded in paraffin. Liquids are automatically dispensed onto the slides according to a predetermined recipe for at least deparaffinizing, staining, and counterstaining the specimens. The slide carrier can be robotically moved out of the stainer after automatically dispensing the liquids. In some embodiments, a total of all liquid dispensed onto the slides after moving the slide carrier into the stainer and before moving the slide carrier out of the stainer has a greater volumetric concentration of polyol than of monohydric alcohol.
    Type: Grant
    Filed: August 23, 2019
    Date of Patent: February 4, 2020
    Assignee: Ventana Medical Systems, Inc.

  • GRAM STAINING METHOD WITH IMPROVED DECOLORIZATION OF THE CRYSTAL VIOLET-IODINE COMPLEX FROM GRAM NEGATIVE BACTERIA
    Publication number: 20160091401
    Abstract: Provided herein are methods of staining biological material for the purpose of detecting, and in some examples also identifying, microorganisms. Methods of Gram staining bacteria using a slow-acting decolorizing formulation, such as one that includes 1,2-propandiol or ethylene glycol, can be used to extend the time of the decolorizing step, and thus permit automation of the Gram staining method. Also provided are compositions and kits for performing automated Gram staining on microscope slides.
