stem cell patent?

Steven Salzberg, a Professor of bioinformaticsat at the University of Maryland, raised the question of patenting stem cells by WARF - Wisconsin Alumni Research Foundation. Many aspects involved here, for example, is patent a good thing at all? Is patenting research a good thing? Is patenting research funded by public money a good thing? Look at people's comments. Interesting topic to discuss.

My point is simple: patent them but give them free (or almost free) to academic researches.
