Stem cell patents held by a University of Wisconsin organization are so restrictive that they create an impediment to research, according to a science journal published Friday.
The authors, California stem-cell researcher Jeanne F. Loring and patent attorney Cathryn Campbell, said the Wisconsin Alumni Research Foundation patented stem cells so broadly that other researchers can do little without infringing on the foundation’s patents.
The article appears in Friday’s issue of the journal Science.
