Diagnostic Tool Patent Held Valid

In another boost to medical innovators, a Federal Circuit panel has ruled claims as valid in a patent by CardioNet for identifying atrial fibrillation. The patent discloses using “relevance determination logic” to identify when heartbeat irregularities are ‘relevant’ and to trigger an ‘event generator’ to take appropriate action. This case cites McRo in support, which underscores the importance of claiming an improved method in software-type patents — how it was actually done — and not the entire ‘end result.’ By leaving the end result open to be reached in other undiscovered ways, the claims can more likely avoid invalidity due to pre-emption concerns.
