Rajkumar Siva Iyer 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).

  • Non-nucleotide linking reagents
    Patent number: 6130323
    Abstract: Non-nucleotide reagents capable of forming oligomers with nucleotide units are disclosed, together with intermediates for synthesizing such non-nucleotide reagents, oligomers incorporating such reagents, kits containing such reagents and methods for their use in forming oligomers with nucleotide units.
    Type: Grant
    Filed: October 26, 1998
    Date of Patent: October 10, 2000
    Assignee: BioGenex Laboratories
    Inventors: Sheng-Hui Su, Rajkumar Siva Iyer, Sunil K. Aggarwal, Krishan L. Kalra
  • Multifunctional linking reagents for synthesis of branched oligomers
    Patent number: 5916750
    Abstract: Reagents capable of forming branched oligomers with monomeric units are disclosed, together with oligomers incorporating such reagents, kits containing such reagents and methods for use of such reagents in forming oligomers with monomeric units. The present reagents can advantageously be used to introduce multiple labels or reporter molecules onto oligomers such as oligonucleotides and oligopeptides. In particular, non-nucleosidic phosphoramidites based on 1,3,5-tris(2-hydroxyethyl)cyanuric acid are disclosed. Multiply-labeled, branched DNA oligomer probes constructed using these phosphoramidite reagents showed increased signal intensity relative to singly-labeled oligomer probes.
