Greenpeace Challenges Stem Cell Patent

From The Scientist:

"The German arm of the environmental lobby group Greenpeace is disputing a patent awarded earlier this year to a leading researcher on the grounds that it allows the commercial exploitation of human stem cells.

The organization filed a notice of opposition with the German Patent Office on Wednesday (October 20) against a patent granted in May to Oliver Brustle from the University of Bonn. The patent covers a cell culture method related to a process for deriving neural cells from embryonic stem cells."
