Angiotech wins before the UK House of Lords

    VANCOUVER, July 10 /CNW/ - Angiotech Pharmaceuticals, Inc. (NASDAQ:   ANPI,
TSX: ANP), a global specialty pharmaceutical and medical device company,
announced that yesterday, the highest court of the United Kingdom, the House
of Lords, confirmed in a precedent-setting decision the validity of one of
Angiotech's patents related to its paclitaxel stent inventions. As Lord
Neuberger of Abbotsbury, commented, "The decision represents a significant
development in the United Kingdom patent law".
    "We are pleased that the House of Lords entered final judgment in
Angiotech's favor and view this outcome as further proof of the continued
strength of our paclitaxel stent patent portfolio throughout the world," said
Dr. Bill Hunter, President and CEO of Angiotech. "We remain committed to
vigorously protecting our proprietary technologies and defending our
intellectual property, and reaching supportive conclusion on this decision
reaffirms this commitment," added Dr. Hunter.
    The patent at issue was granted to Angiotech Pharmaceuticals Inc. by the
European Patent Office (the "EPO") on June 25, 1997. At the EPO, five
different companies opposed the patent. After over nine years of legal battles
their challenge proved unsuccessful and the validity of the patent was
maintained. On February 1, 2005, Angiotech commenced suit against Conor
Medsystems Inc. ("Conor") in the Netherlands. Conor responded by commencing
proceedings in the UK to revoke the patent. Conor argued that, as of July 1993
(the priority date), the claims in the patent lacked inventive step (i.e.,
were obvious) under UK law.
    Both the UK trial court and the UK Court of Appeal decided that the
patent was invalid in view of several publications. Within the same time frame
several courts in the Netherlands, following the approach of the EPO and
concluded that Angiotech's claimed invention was inventive and not obvious in
view of the same publications. Angiotech appealed the UK lower court decisions
to the House of Lords seeking to resolve these inconsistent outcomes.
    In his lead opinion upholding the validity of Angiotech's patent, Lord
Hoffmann did not agree with the reasoning that the UK lower courts used in
justifying revocation and instead agreed with the opinion of the Dutch Court.
The House of Lords' unanimous decision reflects an important development in
bringing uniformity to the interpretation of the European Patent Convention
among the national courts of Europe and the European Patent Office.
