309 F. Supp. 3d 171
S.D. Ill.2018Background
- Quantum Stream owns three patents ('626, '228, '136) titled “Content Distribution System and Method” claiming systems that select and insert secondary (advertising) content into vacancies in primary digital content based on attributes (e.g., consumer profile, location, time).
- The patents share the same specification; claims vary only in generic arrangements of servers, network connectors, consumer devices, storage, and processors to select and insert targeted ads (some claim real-time insertion).
- Quantum sued Charter for patent infringement and alleged at least claim 1 of each patent was infringed; Charter moved to dismiss under Rule 12(b)(6) arguing the patents are invalid under 35 U.S.C. § 101 as directed to abstract ideas.
- The district court treated claim 1 of each patent as representative (claims are substantially similar for § 101 purposes) and applied the Alice/Mayo two-step framework without needing claim construction.
- The Court concluded the patents are directed to the abstract idea of customized advertising (matching ads to user/ content attributes) and that the claims add only generic computer components and conventional steps, lacking an inventive concept.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the asserted claims are directed to patent-eligible subject matter under § 101 | Quantum: claims improve computer systems by enabling real-time, attribute-based ad insertion (a paradigm shift over preinserted ads) and recite specific system arrangements | Charter: claims merely recite the abstract idea of tailoring advertising and use generic computer components to implement it | Held: Claims are directed to the abstract idea of custom advertising and are therefore patent-ineligible |
| Whether the claims contain an "inventive concept" under Alice step two | Quantum: specific arrangements (servers, connectors, processors), delivery of ads separate from programs, and real-time insertion supply inventive concept | Charter: these are conventional computer components and routine steps; real-time or efficiency gains do not transform the abstract idea | Held: No inventive concept — claims use generic devices and steps that could be performed mentally or by humans; insufficient to confer patentability |
| Whether claim construction is required before resolving § 101 | Quantum: premature to decide § 101 without claim construction | Charter: not necessary because claims are invalid under any reasonable construction | Held: Claim construction unnecessary; patents invalid under § 101 under any reasonable construction |
