I would like to take a moment to reflect on the entirely fucked up system that would a) produce people who think it makes sense to patent human genes, b) produce a patent office that would allow this, c) lead to corporations feeling that they have the right to do this:
[Myriad Genetics, Inc.] had a patent on a gene which can lead to breast cancer. Refusing to license the gene to other companies, Myriad had a monopoly on tests for the gene, which meant many women were denied the ability to discover whether they had an increased risk for cancer.and d) leave the whim of some judge someone appointed as our only defense against this blatantly evil set of circumstances. I could write a whole long post about just point d, how fucked up our judicial system is, but I won't right now.
Because in practical terms this ruling is a very very good thing. A relatively minor good thing, sure, a mere drop of fresh water in an ocean of shit, but that one drop is still something to be happy about.
