CardioNet, LLC v. InfoBionic, Inc., No. 19-1149 (Fed. Cir. 2020)
Annotate this Case
CardioNet’s 207 patent, titled “Cardiac Monitoring,” claims priority to an application filed in 2004 and describes cardiac monitoring systems and techniques for detecting and distinguishing atrial fibrillation and atrial flutter from other various forms of cardiac arrythmia. The district court dismissed CardioNet’s patent infringement complaint against InfoBionic, finding that the asserted claims of the patent are ineligible under 35 U.S.C. 101.
The Federal Circuit reversed, applying the Supreme Court’s two-step “Alice” framework and finding that the asserted claims of the 207 patent are directed to a patent-eligible improvement to cardiac monitoring technology and are not directed to an abstract idea. Nothing in the record suggests that the claims merely computerize pre-existing techniques for diagnosing atrial fibrillation and atrial flutter.
