348 F. Supp. 3d 87
D.D.C.2018Background
- CardioNet (licensee) and Braemar (patentee) sued InfoBionic for alleged infringement of U.S. Patent No. 7,941,207 (the '207 patent) relating to cardiac monitoring for detecting atrial fibrillation/atrial flutter (AF).
- The asserted claims describe a device or software that: detects beats, identifies ventricular (premature) beats, determines beat-to-beat variability via unspecified "determination logic," assesses relevance to AF, and generates an event/notification; dependent claims add weighting, specific interval comparisons, non-linear functions, sensors, and transmission to a remote receiver.
- InfoBionic moved to dismiss under Fed. R. Civ. P. 12(b)(6), arguing the claims are patent-ineligible under 35 U.S.C. § 101 as interpreted by Alice and its progeny because they are directed to an abstract idea and add only conventional computer components.
- Plaintiffs argued the claims improve cardiac-monitoring functionality (better AF detection via specific programmed rules and beat-detection arrangements) and analogous to claims found eligible in Bascom/Amdocs/the parties' prior T-wave-filter litigation.
- The district court applied the two-step Alice framework, accepted plaintiffs’ factual pleadings and claim constructions for purposes of the motion, and concluded the claims are directed to an abstract idea and lack an inventive concept in their elements and combination.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether claims are directed to an abstract idea under Alice step 1 | Claims improve cardiac-monitoring devices and are directed to a concrete improvement in signal processing for AF detection | Claims are the abstract idea of identifying AF by analyzing beat-to-beat variability and accounting for ventricular beats—conventional diagnostic reasoning automated by generic components | Court: Directed to an abstract idea (monitoring/analyzing beat variability to identify AF) |
| Whether claim elements supply an "inventive concept" under Alice step 2 | "Determination logic" plus beat detectors/event generators provide a technical solution and mirror Bascom/Amdocs/T-wave-filter precedents | Claim elements are generic hardware/software; determination logic is undefined; added limitations are conventional data collection/processing and do not meaningfully limit scope | Court: No inventive concept; elements are generic/conventional and do not transform the abstract idea |
| Whether dependent claims (weighting ventricular beats, three QRS comparisons, non-linear function, remote transmission) rescue eligibility | These limitations narrow and specify technical rules that solve prior art inaccuracies and enable real-time/out-of-clinic detection | Limitations are generic calculations or conventional steps; they do not specify how to implement the logic and thus add nothing inventive | Court: Dependent limitations insufficient to confer eligibility |
| Procedural: Whether §101 is resolvable on 12(b)(6) given Berkheimer | Plaintiffs contend Berkheimer makes step 2 fact-dependent such that dismissal may be premature | Defendant says facts in complaint and patent documents are definitive and establish ineligibility as a matter of law | Court: No factual disputes here; dismissal proper on the pleadings because claims, as pleaded/construed, lack a plausible inventive-concept theory |
