Charles Keller 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: 7150883
    Abstract: A lipid composition forms liposomes spontaneously upon mixing with an aqueous solution. The lipid composition includes diacylglycerol-PEG compounds. Such lipid compositions are useful for forming liposomes, which in turn are useful for a variety of purposes, including the delivery of therapeutic agents.
    Type: Grant

  • Publication number: 20060194200
    Abstract: A high-throughput assay for characterizing a subject's genetic makeup is disclosed. Specifically, a high-throughput assay utilizing PCR is disclosed that permits the rapid and accurate characterization of a subject's inherited alleles of the polymorphic glutathione S-transferase (GST) genes GSTM1, GSTM3, GSTP1, and GSTT1. This method allows detection of the specific alleles inherited, including the gene dosage of GSTM1 and GSTT1 while not requiring restriction endonuclease digestion of the PCR products in order to detect length differences. Further, the method allows all analyses to be performed simultaneously in the same gel lane, thus further adding efficiency and cost-effectiveness.

  • Patent number: 6958160
    Abstract: A liposome suspension forms spontaneously upon adding a lipid composition to an aqueous solution. The liposomes include diacylglycerol-PEG compounds. The melting point of the diacylglycerol-PEG is below about 40 degrees C., and the acyl chains of the diacylglycerol-PEG are greater than or equal to 14 carbons in length. Such liposome suspensions are useful for a variety of purposes, including the delivery of therapeutic agents.

  • Patent number: 6877136
    Abstract: The present invention provides a system and method of providing electronic access to one or more documents. In one embodiment, a storage device retains eligibility information relating to each document. Eligibility information provides the system with information such as the document type, the applicable line of business, governmental regulations, time sensitive information, and security requirements. If a given document is determined to be eligible, the processing unit of the present invention retrieves one or more preference instructions provided by the customer. The preference instructions are reviewed to confirm 1) whether the customer has authorized electronic access to a given document and 2) the mode of electronic transmission favored by the customer. In one embodiment, the present invention is connected to a computer network such that the customer may be provided electronic access to his or her documents through a web interface.

  • Patent number: 6610322
    Abstract: A liposome suspension forms spontaneously upon adding a diacylglycerol-PEG lipid to an aqueous solution when the lipid has appropriate packing parameters and the adding occurs above the melting temperature of the lipid. Combinations of lipids may be used in the invention. The liposome suspensions are useful for a variety of purposes, including delivery of theraputic agents.

  • Patent number: 6024126
    Abstract: A uniform cross-section and ribbed thermoplastic compressor valve which can be used as a discharge valve for a compressor and has internal rib structure and uniform wall thickness. The valve member can be made of high-performance polymeric resin such as polyimide. The valve member comprises a base member, an annular wall member, a central member protruding from the base member, and a plurality of internal wall members. The internal wall members provide the internal rib structure which strengthens the valve member and allows for light-weight construction. Preferably, there are six internal wall members and the central member has a cavity.

  • Patent number: 5968737
    Abstract: Complementary DNA and genomic clones for three variants of GST-.pi. are disclosed. It is demonstrated that certain of these variants are overexpressed in gliomas, thereby indicating an involvement with that form of cancer. This permits the detection and treatment of certain classes of tumors using new compositions such as GST-.pi. genes, oligonucleotides, peptides and antibodies.
