for The Association of the Bar of the City Of New York
1. Pharmastem Therapeutics, Inc. v. Viacell, Inc., 05-1490, 05-1551, UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT, July 9, 2007, Decided
OVERVIEW: Patents related to method of collecting, cryopreserving, thawing, and infusing umbilical cord stem cells were not infringed, since it was not shown that competitors collected sufficient stem cells and competitors only collected and preserved cells, and patents were invalid as obvious since prior art inferred presence of stem cells in cord blood.
