Pharmastem Therapeutics, Inc. v. Viacell, Inc., 491 F.3d 1342 (Fed. Cir. 2007)

Posted by LexisNexis Patent Law Center Staff

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.
