Patents by Inventor Roy Clifford Levitt

Roy Clifford Levitt 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: 8637469
    Abstract: The invention describes a method of treating upper airway disease by administering a composition of one or more proinflammatory cytokine inhibitors sufficient to inhibit inflammation in the upper airways. The proinflammatory cytokines that are inhibited include TNF, IL-1 and IL-8. A medication dispensing unit which includes a container and a delivery system is used to administer the composition. The delivery system further encompasses a one-way valve, a microcatheter, or a liquid-pressure type sprayer.

  • Publication number: 20110224406
    Abstract: This invention relates to the diagnosis, treatment and methods for discovery of new therapeutics for atopic asthma and related disorders based on variants of Asthma Associated Factor 2. One embodiment of the invention is a variant of AAF2 wherein codon 173 is deleted resulting in the loss of glutamine 173 from the mature protein precursor. This single amino acid deletion results in a non-functional AAF2 protein and therefore the presence of this phenotype should be associated with less evidence of atopic asthma. Correspondingly, the lack of susceptibility to an asthmatic, atopic phenotype is characterized by the loss of glutamine at codon 171 The invention includes isolated DNA molecules which are variants of the wild type sequence as well as the proteins encoded by such DNA and the use of such DNA molecules and expressed protein in the diagnosis and treatment of atopic asthma.

  • Publication number: 20110224153
    Abstract: A C to T DNA variation at position 3365 in exon 5 of the human Asthma Associated Factor 1 (AAF1) produces the predicted amino acid substitution of a methionine for a threonine at codon 117 of AAF1. When this substitution occurs in both alleles in one individual, it is associated with less evidence of atopic allergy including asthma, fewer abnormal skin test responses, and a lower serum total IgE. Thus, applicant has identified the existence of a non-asthmatic, non-atopic phenotype characterized by methionine at codon 117 when it occurs in both AAF1 gene products in one individual.
