Patents by Inventor Paul V. Lehmann

Paul V. Lehmann 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: 8088630
    Abstract: Embodiments of the present invention relate to devices and methods for detecting cellular products using detection particles having product-specific detection reagents and having a characteristic spectral feature. In particular, devices and methods are provided for measuring secreted cellular products including cytokines. Detection substrates, include microwells having product-specific capture reagents thereon or comprising hydrophobic membranes are described having greater capability to detect products from individual cells in a mixture of heterogeneous cells. With the use of multiple detection particles, multiple cellular products can be detected in a single well. Additionally, using the inherent spectral properties of detection particles, no enzymatic reactions are needed to visualize a secreted product, thereby increasing the sensitivity, reproducibility and ease of use.

  • Publication number: 20090141132
    Abstract: Embodiments of this invention include flatbed scanners that have a surface and have a plurality of light sources. Alternatively, a single light source can be moved in two dimensions relative to an object placed on the surface of the scanner. Other embodiments include a scan head that is moveable in two dimensions relative to the flat bed of the scanner. Further embodiments include one or more polarizing filters to reduce glare and increase the quality of a captured image. Theses scanners can be used to capture images of enzyme linked immunosorbent assay (ELISA) substrates, plates having cultures thereon or other objects having irregular lower surfaces. Additional embodiments include methods for capturing images from ELISA substrates, bacterial culture plates, viral plaque assay plates and the like.
