Kenneth R. Luehrsen 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: 10919983
    Abstract: The invention provides methods for generating human antibodies with the specificity of a reference antibody by replacement of portions of the VH and VL sequences of the reference antibody with sequences from human antibody repertoires. The invention also provides novel compositions comprising hybrid immunoglobulin variable domains containing a combination of frameworks (FRs) and CDRs from different antibody clones.
    Type: Grant
    Filed: December 14, 2015
    Date of Patent: February 16, 2021
    Assignee: HUMANIGEN, INC.

  • Patent number: 8642035
    Abstract: The present invention provides improved antibodies or antigen-binding molecules that specifically recognize and agonize the tyrosine receptor kinase B (TrkB) receptor, and methods of their use. Also provided in the invention are polynucleotides and vectors that encode such molecules and host cells that harbor the polynucleotides or vectors.

  • Patent number: 6986992
    Abstract: This invention relates to methods and compositions for determining single nucleotide polymorphisms (SNPs) in P450 genes. In preferred embodiments, self extension of interrogation probes is prevented by using novel non self-extension probes and/or methods, thereby improving the specificity and efficiency of P450 SNP detection in target samples with minimal false positive results. The invention thus describes a variety of methods to decrease self-extension of interrogation probes. In addition, this invention provides a unique collection of P450 SNP probes on one assay, primer sequences for specific amplification of each of the seven P450 genes and amplicon control probes to evaluate whether the intended p450 gene targets were amplified successfully. The invention also describes a variety of array platforms for performing the assays of the invention; for example: CodeLinkā„¢, eSensorā„¢, multiplex arrays with cartridges etc., all described herein.
