When an artery is damaged or inflamed, the body releases the enzyme myeloperoxidase (MPO). Prior art taught that MPO could be detected in an atherosclerotic plaque or lesion that required a surgically invasive method; could be indirectly detected in blood; or could be detected in blood with results that were not predictive of cardiovascular disease. Cleveland Clinic purportedly discovered how to “see” MPO in blood and correlate that to the risk of cardiovascular disease. True Health, a diagnostic laboratory, purchased the assets of Diagnostics, which had contracted with Cleveland Clinic to perform MPO testing. Rather than continue that relationship, True Health performed its own MPO testing. Cleveland Clinic sued, asserting infringement of the patents. The district court found all the claims patent-ineligible under 35 U.S.C. 101; dismissed the contributory and induced infringement claims of the 260 patent; denied leave to amend; and held that it was proper to consider section 101 at the motion to dismiss stage.. The court found that the claims were directed to a law of nature, with no saving inventive concept. The Federal Circuit affirmed. Cleveland Clinic provided no proposed construction of any terms or proposed expert testimony that would change the analysis. The claims, whether considered limitation-by-limitation or as a whole, do not sufficiently transform the natural existence of MPO in a bodily sample and its correlation to cardiovascular risk into a patentable invention.
