Danisco U.S. Inc. v. Novozymes A/S
744 F.3d 1325
Fed. Cir.2014Background
- Danisco appeals a district court dismissal for lack of subject matter jurisdiction in a declaratory judgment action against Novozymes.
- Danisco and Novozymes compete in Rapid Starch Liquefaction (RSL) enzymes for converting plant material to ethanol, with overlapping α-amylase patents.
- Danisco owns U.S. Patent 8,084,240 (the ’240 patent) claiming an E188P substitution in a BSG α-amylase variant used in RSL products.
- Novozymes’ sole claim on its later-issued ’573 patent covers the same BSG E188P α-amylase variant and has asserted it against Danisco’s products in prior disputes.
- District court held there was no justiciable controversy because Danisco hadn’t faced enforcement actions pre-issuance and the dispute would be speculative.
- The panel reverses, finding a justiciable controversy based on the totality of circumstances and remands for further proceedings on Counts 1–2 and Count 3.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether a justiciable controversy exists at filing. | Danisco asserts a real risk of enforcement and infringement claims by Novozymes. | Novozymes argues no immediate threat and relies on pre-enforcement posture. | Yes; totality of circumstances shows a concrete controversy. |
| Whether pre-issuance conduct can create jurisdiction. | Pre-issuance actions and prosecution history support an affirmative act creating controversy. | Pre-issuance conduct cannot sustain jurisdiction absent enforcement actions. | Yes; pre-issuance conduct can support jurisdiction under totality-of-circumstances. |
| Whether the district court erred by applying a bright-line pre- vs post-issuance rule. | Totality of circumstances governs, not a rigid pre/post rule. | Dispositive pre-issuance conduct is insufficient to create controversy. | Yes; flexible totality-of-circumstances test applies. |
| Whether Count 3 (priority under 35 U.S.C. § 291) is ripe or should be retried after reversal. | Count 3 should proceed given potential priority dispute. | Ripeness depends on Counts 1–2; with dismissal reversed, reexamination is needed. | Remanded; count reinstated on remand after reversal. |
