48 F.4th 1282
11th Cir.2022Background:
- In 2014 Knepfle crashed her motorcycle; she alleges her Z1R Nomad half‑shell helmet flew off after an initial impact with a car, causing a secondary unhelmeted head impact and permanent injury.
- The helmet was a Z1R Nomad private‑label model sold by LeMans; HJC (a South Korean manufacturer) designed and manufactured the helmet overseas; HJCA is HJC’s U.S. subsidiary that markets HJC‑branded helmets (but not the Z1R private label) and lists U.S. retailers.
- Knepfle’s liability case alleged a design defect in the helmet’s double D‑ring fastening system and causation relying on expert Dr. John D. Lloyd, who opined the D‑rings could loosen and that visible rear liner markings showed the helmet was off for the second impact.
- Lloyd’s methods: visual ("eyeballing") inspection of rear liner (no caliper/3D measurement), a demo flipping an empty helmet to show strap geometry, pendulum tests comparing helmeted vs. unhelmeted impacts, and anthropometric data about strap length; he did not test D‑ring performance under real‑world conditions.
- The district court excluded Lloyd’s testimony under Daubert/Rule 702 as unreliable, granted summary judgment for defendants, and denied HJC’s separate personal‑jurisdiction motion as moot; HJC cross‑appealed the jurisdiction ruling.
- The Eleventh Circuit reversed the denial of HJC’s personal‑jurisdiction motion (district court erred by attributing HJCA’s contacts to HJC without veil‑piercing/alter‑ego analysis), and affirmed the exclusion of Lloyd’s testimony and the grant of summary judgment on the merits.
Issues:
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Personal jurisdiction over foreign parent (HJC) based on U.S. subsidiary marketing | HJC knew its helmets reached Florida via U.S. presence; HJCA’s website/retailer list shows HJC sought Florida market | HJC did no business in Florida; HJCA’s marketing cannot be imputed to HJC absent veil‑piercing or alter‑ego showing | Reversed denial of HJC’s jurisdictional motion: district court erred by attributing HJCA’s contacts to HJC without veil‑piercing/alter‑ego analysis; no specific jurisdiction over HJC |
| Admissibility of expert testimony re: lack of rear liner compression (visual inspection) | Lloyd is qualified; visible lack of rear compression supports helmet-off-at‑second‑impact finding; visual inspection is sufficient for "relevant" compression | Lloyd failed to use accepted measurement methods (calipers/3D); relied on ipse dixit and inconsistent methodology | Affirmed exclusion: visual "eyeballing" was unreliable, Lloyd conceded accepted practice uses measurements; large analytical gap between data and conclusion |
| Admissibility of expert testimony re: D‑ring design defect and strap failure (demo) | D‑ring geometry and short strap length create loosening risk; demonstration and anthropometric data support defect/causation | Lloyd performed no real‑world or standardized testing of the double D‑ring system; demo used an empty helmet and did not replicate in‑use conditions | Affirmed exclusion: methodology not generally accepted or shown to reflect real‑world conditions; insufficient testing and analytical support |
| Summary judgment on products‑liability claims after excluding expert | Expert testimony creates factual dispute on defect and causation | Without admissible expert proof, plaintiff lacks evidence of defect/causation | Affirmed summary judgment for defendants: exclusion of Lloyd left no material factual dispute on defect or causation |
