And we’re not just talking genetically modified corn – your genes, pretty much as they exist in your body, can and have been patented. The US government reports over three million gene patent applications have been filed so far; over 40,000 patents are held on sections of the human genome, covering roughly 20% of our genes. Upset? You’re not alone.
