This patent covers freezing of cord blood for future use. The patent has one independent claim covering the composition of a cryopreservant, together with viable fetal or neonatal hematopoietic cells. PharmaStem is the successor to Biocyte Corporation, the assignee of this patent. This patent, together with patents 5 192 553, 6 461 645, 6 569 427 and 6 605 275 are used by Pharmastem to enforce its intellectual property rights to the cord blood banking as practiced today. These patents have all been litigated and to my knowledge, at least substantially remain intact.
