The two foundations questioning the validity of the Wisconsin Alumni Research Foundation’s key embryonic stem cell patents have bolstered their protest with comments from three more scientists.
The comments were filed with the U.S. Patent and Trademark Office, the groups said Monday. Douglas Melton and Chad Cowan of Harvard University and Alan Trounson of Monash University in Australia joined Jeanne Loring of the Burnham Institute for Medical Research in filing declarations supporting the foundations’ efforts to get the patents overturned.
