    Prospective Grant of Exclusive License: For Nucleic Acid-Based Vaccines and
    Therapeutics

    AGENCY: National Institutes of Health, Public Health Service, DHHS

    ACTION: Notice

    SUMMARY: This is a notice in accordance with 35 U.S.C. 209(c)(1) and 37 CFR 
    404.7(a)(1)(i) that the National Institutes of Health (NIH), Department of
    Health and Human Services, is contemplating the grant of a limited field of
    use exclusive license in the United States to practice the invention embodied
    in U.S. Patent Application Number 08/286,730 entitled, "Liposomal Delivery
    System for Nucleic Acids," and its Continuation-In-Part U.S. Patent
    Application Serial Number 08/522,246, and all related foreign filings
    (PCT/US95/09867), invented by Alain Thierry formerly of the National Cancer
    Institute, to Biovector Therapeutics, S.A of Labage, France. The patent
    rights in these inventions have been assigned to the United States of America.

    DATE: Only written comments and/or applications for a license which are
    received by NIH on or before December 9, 1997 will be considered.

    ADDRESS: Requests for copies of the subject issued patent and pending patent
    applications, inquiries, comments and other materials relating to the
    contemplated license should be directed to: Mr. Larry M. Tiffany, Office of
    Technology Transfer, National Institutes of Health, 6011 Executive Boulevard,
    Suite 325, Rockville, MD 20852; Telephone: (301) 496-7056, ext. 206;
    Facsimile: (301) 402-0220. A signed Confidentiality Agreement will be
    required to receive copies of the pending patent applications.

    SUPPLEMENTARY INFORMATION: The present invention relates to a liposome
    composition comprising a bi- or multi-layered membrane surrounding an internal
    aqueous liposome comprising at least one cationic lipopolyamine and at least
    one neutral lipid provided in a molar ratio range, said ratio from about .02:1
    to 2:1. In addition to the pending composition claims there are also pending
    rights to methods of preparing the liposome composition, pharmaceutical
    compositions including the liposome and methods of introducing nucleic acids
    into cells using the liposome. This invention is advantageous over
    alternative lipid preparations due to its ability to more easily form
    liposomes at physiological temperatures and pH hence making it potentially
    more stable in-vivo.
    The prospective exclusive license will be royalty-bearing and will
    comply with the terms and conditions of 35 U.S.C. 209 and 37 CFR  404.7. The
    prospective exclusive license may be granted unless, within 90 days from the
    date of this published Notice, NIH receives written evidence and argument that
    establishes that the grant of the license would not be consistent with the
    requirements of 35 U.S.C. 209 and 37 CFR  404.7.
    The field of use would be limited to nucleic acid-based vaccines and
    therapeutics.
    Applications for a license to the field of use described in this Notice
    will be treated as objections to the contemplated license. Comments and
    objections will not be made available for public inspection and, to the extent
    permitted by law, will not be subject to disclosure under the Freedom of
    Information Act, 5 U.S.C. 552.
