Additional ex-U.S. equivalents to the above issued patents are currently pending.  The 3’NTR element of the HCV genome as covered by the ‘565 patent (and its EP counterpart) is essential for hepatitis-C viral replication, and hence HCV replicon functioning.  The specification of the ‘116 patent describes the replicon construct and its use.

All worldwide commercial rights under these patents (including the right to issue sublicenses) have been licensed exclusively to Apath by Washington University, St. Louis.

Apath currently has additional patent applications pending covering replicons and/or their use in drug screening:

  • An application with claims specifically directed to the HCV replicon
  • A method for using replicons to screen for multiple viruses simultaneously within the same assay (go to Multivirus Screening for additional information)

In the area of RNA virus detection, Apath is the exclusive licensee (from Washington University, St. Louis) to U.S. 6,270,958 entitled Detection of Negative Stranded RNA Viruses (go to RNA Virus Detection for additional information).
