386 F. Supp. 3d 1185
N.D. Cal.2019Background
- Cisco sued Uniloc seeking a declaration of non‑infringement of U.S. Patent No. 6,980,522 (the '522 patent); Uniloc counterclaimed for infringement of at least claim 6.
- The '522 patent concerns ad‑hoc radio networks (e.g., Bluetooth piconets) and claims ranking stations by antenna performance (and other factors) and enabling the highest‑ranked station to be master.
- Claim 6 recites: determining a master/slave rank of each station using antenna performance characteristics in view of local environment, and enabling the highest‑ranked station to be master.
- Cisco moved for judgment on the pleadings under Rule 12(c), arguing claim 6 is invalid under 35 U.S.C. § 101 as directed to an abstract idea and lacking an inventive concept.
- Uniloc argued the claim solves a specific technical problem and relies on the specification to supply an inventive concept; it relied on several Federal Circuit decisions for eligibility.
- The Court considered Alice’s two‑step framework and resolved the § 101 challenge on a Rule 12(c) record, finding no need for claim construction or contested factual development to decide eligibility.
Issues
| Issue | Plaintiff's Argument (Cisco) | Defendant's Argument (Uniloc) | Held |
|---|---|---|---|
| Whether claim 6 is directed to patent‑ineligible subject matter (abstract idea) | Claim 6 is an abstract idea: ranking items (stations) by a criterion and selecting the best is a fundamental human activity and can be done mentally or with pen and paper. | Claim 6 is a technological solution to a technical problem in ad‑hoc networks (improves network efficiency by using antenna characteristics). | Claim 6 is directed to an abstract idea (ranking/selecting based on antenna performance). |
| Whether claim 6 contains an "inventive concept" that transforms the abstract idea into patentable subject matter | The claim lacks technical detail and merely applies the abstract idea using conventional Bluetooth hardware and protocols; no specific measurement or novel implementation is claimed. | The specification and claim disclose the inventive technique of using antenna performance in view of local environment to form networks and select masters. | No inventive concept: claim recites result‑focused, generic steps and conventional technology; invalid under Alice step two. |
| Appropriateness of resolving § 101 on a Rule 12(c) motion | Eligible for early resolution because the pleadings and intrinsic record show the claim is abstract and lack factual disputes affecting eligibility. | Allegations in Uniloc's counterclaim that the patent is technical must be accepted as true; factual issues preclude dismissal. | Court may decide § 101 on a Rule 12(c) record; Uniloc’s relevant allegations were conclusory and insufficient to create a factual dispute. |
| Whether claim limitations (e.g., use of antenna performance or Bluetooth protocols) render claim patent‑eligible | Such limitations are generic and conventional; recitation of routine computer/communication components does not render the claim eligible. | Limiting to ad‑hoc radio networks and antenna‑based ranking confines the claim to a technological environment and is an inventive application. | Generic network components and conventional Bluetooth methods do not supply the required inventive concept. |
