Meanwhile, a growing number of researchers, health care providers, and public interest groups have raised concerns about the harms of gene patents. The American Civil Liberties Union estimates that more than 40 percent of genes are now patented. Those patents have created “patent thickets” that make it difficult for scientists to do genetic research and commercialize their results. Monopolies on genetic testing have raised prices and reduced patient options.

But the legal challenge, spearheaded by the American Civil Liberties Union and the Public Patent Foundation, could have much broader implications. A decision could invalidate thousands of patents and free medical researchers and clinicians to practice medicine without interference from the patent system. [Continue reading…]
