Opponents of the 2006 James Thomson patent say that it should be thrown out based on the same logic that led the U.S. Supreme Court to rule out patents on human genes—they are a product of nature. Even if this argument succeeds, however, many researchers say it won't have a big impact on stem cell work because so many labs are now using a different and more artificial technology—induced pluripotent stem cells.
