The Patent Plot Thickens

The Wisconsin Alumni Research Foundation has been fighting to keep their patents on the isolation of human embryonic stem cells after their patents were challenged by various scientists and organization and preliminarily rejected. Today, WARF has this press release noting an Information Disclosure Statement they've submitted to U.S. Patent and Trademark Office about how two of the researchers (Alan Trounson and Jeanne Loring) who challenged the validity of WARF's embryonic stem cell research patents (with the argument that the research was obvious at the time based on research with mice cells) also applied for patents after they isolated embryonic stem cells.
