The US Supreme Court ruled today that human genes cannot be patented. Here is the link to the New York Times article. The specific case regards Myriad Genetics, which held a patent that controlled the rights to all tests for the BRCA1 and BRCA2 genes implicated in breast cancer. The patent essentially blocked most research on the BRCA genes. The immediate effect will be that genetic testing will become cheaper and more widespread. People will argue that not allowing genes to be patented will discourage further innovation. I doubt it. Most discoveries, like genes, come from basic federally funded research. Any company can now develop a test for any newly discovered gene. Patent law has been broken for decades and this is just one small step to correcting it.
