U.S. Patent & Trademark Office Rejects Vitrolife Patent Claims

    GUILFORD, Conn., June 26 /CNW/ -- In November 2005, IVFonline.com, LLC,
among others, was sued for patent infringement of U.S. Patent No. 6,838,235
(the '235 patent) by Vitrolife, AB of Sweden (Vitrolife).  In particular,
Vitrolife claimed the exclusive right to market embryo culture medium
containing alanyl-glutamine.  Since that time, IVFonline has vigorously
defended itself believing that the patent was invalid based upon the prior art
and prior use.
    In October 2006, the U.S. Patent and Trademark Office (PTO) re-examined
the patent and rejected, as anticipated and/or obvious, all of the claims of
the '235 patent.  Vitrolife responded to the rejection but the PTO, for the
second time, rejected all the '235 patent claims and closed prosecution.
    A representative of IVFonline, said that the decision of the PTO to
reject all of the patent claims reaffirms their position that the Vitrolife
patent is invalid and thus, IVFonline was not in violation.
    The representative went on to say that the IVFonline's scientific team,
lead by Dr. John D. Biggers, had already developed a superior IVF embryo
culture medium using glycyl-glutamine, which is now in the market and
beginning to change the way reproductive specialists culture embryos.
    IVFonline and its affiliates are world leaders in IVF products,
especially IVF embryo culture media, branded as LifeGlobal, and have a broad
group of loyal customers worldwide.
