817 F.3d 621
8th Cir.2016Background
- Andover Healthcare (plaintiff) and 3M (defendant) both make cohesive, latex-free bandages; Andover holds related U.S. and European patents and sued 3M for infringement in Germany (and earlier in Delaware).
- Central technical dispute: Andover’s European patent requires a polychloroprene elastomer that is at least partially polycrystalline; 3M’s German-defense expert reported 3M’s elastomer is non‑crystalline, so tackifiers cannot "disrupt" crystallinity and thus no infringement.
- Andover sought 3M’s polychloroprene formulation and crystallinity data to run comparative tests; 3M refused, citing highly sensitive trade secrets.
- 3M produced the information under protective order in the Delaware case; the Delaware court denied Andover permission to use that discovery in Germany. Andover’s request to the German court was pending.
- Andover petitioned the U.S. District Court for the District of Minnesota under 28 U.S.C. § 1782 for discovery for use in the German suit; the district court denied the petition, and the Eighth Circuit affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether §1782 discovery should be ordered for use in German patent litigation | Andover: §1782 permits discovery to aid foreign proceedings; evidence sought is necessary and admissible in Germany | 3M: Information is highly sensitive trade secret; 3M is a party in the German case and the German court can and will order discovery if needed | Denied: District court did not abuse discretion in refusing §1782 discovery |
| Weight of respondent’s participation in foreign proceeding | Andover: Participation by 3M in Germany does not preclude U.S. §1782 relief because German discovery may be limited | 3M: As a party in Germany, 3M is subject to foreign court’s compulsion, reducing need for §1782 aid | Court: Intel factor favors denying §1782 because the German tribunal can order 3M to produce evidence |
| Whether trade-secret sensitivity and foreign confidentiality procedures defeat §1782 relief | Andover: Protective orders can safeguard confidentiality and German courts admit U.S.-obtained evidence | 3M: Disclosure would risk irreparable harm; German procedures may not adequately protect secrets | Court: Sensitivity and uncertain foreign protection weigh heavily against discovery; protective order insufficient given need to file to German court |
