Prism Technologies LLC v. T-Mobile USA, Inc.
696 F. App'x 1014
Fed. Cir.2017Background
- Prism Technologies sued T‑Mobile for infringement of U.S. Patents Nos. 8,127,345 and 8,387,155, which claim methods/systems for controlling access to protected computer resources over untrusted networks by authenticating device "identity data."
- The district court denied T‑Mobile’s § 101 summary judgment motion and granted Prism’s cross‑motion; the case proceeded to trial and a jury found for T‑Mobile (non‑infringement).
- Both parties filed post‑verdict motions: Prism sought a new trial and JMOL of infringement; T‑Mobile sought JMOL of patent ineligibility under § 101 and an exceptional‑case finding under 35 U.S.C. § 285.
- The district court denied all post‑verdict motions. Prism appealed the denial of a new trial/JMOL; T‑Mobile cross‑appealed the district court’s § 101 ruling and the denial of § 285 relief.
- The Federal Circuit reviewed § 101 de novo and § 285 for abuse of discretion; it evaluated the asserted claims under the two‑step Alice framework and examined whether the claims contained an inventive concept beyond an abstract idea.
Issues
| Issue | Plaintiff's Argument (Prism) | Defendant's Argument (T‑Mobile) | Held |
|---|---|---|---|
| Patent eligibility under § 101 | Claims solve a real problem via a concrete solution: using hardware identity data with conventional components yields a novel, effective security method | Claims are directed to the abstract idea of restricting access and only recite generic computer components and conventional identifiers, lacking an inventive concept | Reversed district court: claims are patent‑ineligible under § 101 (fail Alice step 1 as abstract and step 2 for lack of inventive concept) |
| Exceptional‑case finding under § 285 | (Prism) defended its litigation conduct and claim strength based on prior successful assertions against competitors | (T‑Mobile) argued Prism’s case was exceptionally weak, Prism elicited misleading testimony, and advanced a new unsupported infringement theory at closing | Affirmed district court: no abuse of discretion in denying § 285 relief to T‑Mobile |
