Patents by Inventor Peter Liljestrom

Peter Liljestrom 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).

  • DNA expression systems based on alphaviruses
    Patent number: 6770283
    Abstract: The disclosure describes recombinant alphavirus RNA molecules and expression of heterologous proteins therefrom in animal cells. Recombinant alphaviruses of the present invention, when made to express an antigenic protein, can be administered as vaccines.
    Type: Grant
    Filed: October 17, 2000
    Date of Patent: August 3, 2004
    Assignee: Bioption AB
    Inventors: Henrik Garoff, Peter Liljeström
  • Alphavirus cDNA vectors
    Patent number: 6566093
    Abstract: The present invention is related to polynucleotide molecules and to their use for production of desired products after introduction into human or animal cells. In addition, the present invention is concerned with pharmaceutical compositions comprising said polynucleotide molecules and their use in prophylactic or therapeutic treatment methods. The present invention is also related to use of such polynucleotide molecules in animals to achieve expression of desired products, which can be recovered from the animal but do not give rise to any beneficial, e.g. therapeutic, activity in the animal. More specifically, the present invention is directed to alphaviruus cDNA vectors comprised of recombinant cDNA consisting of cDNA derived from an alphavirus and heterologous, i.e. foreign, cDNA encoding a desired substance.
