A case that could have big implications for patent law and the medical profession has reached the country's top court. MPR reports that lawyers for the Mayo Clinic on Wednesday morning will argue that a rival's blood-test patent goes too far. They say the patent also tries to cover the test's results. Prometheus sued Mayo for patent infringement after the clinic created its own blood test.
Mayo Clinic wins major patent victory
The Supreme Court sided unanimously with Mayo in a patent dispute with California-based Prometheus Laboratories. The clinic had used a blood test developed by Prometheus until 2004, when it developed its own in-house test. Prometheus sued for patent infringement, but Mayo argued that using test to measure a natural bodily process is not patent eligible.
