Zup, LLC v. Nash Manufacturing, Inc.
896 F.3d 1365
Fed. Cir.2018Background
- ZUP, LLC owns U.S. Patent No. 8,292,681 covering a water-recreation board (the "ZUP Board") and a method of riding that board using side-by-side front handles and side-by-side middle foot bindings used simultaneously to help a rider transition from prone/kneeling to standing. Claims 1 and 9 are at issue.
- Nash Manufacturing developed and sold a competing product, the "Versa Board," which has configurable holes allowing handles and bindings to be attached in various positions; Nash cautions against certain configurations but a user could place handles and bindings to mimic ZUP's layout.
- ZUP sued Nash for contributory and induced infringement and related claims; Nash counterclaimed for invalidity and noninfringement.
- The district court granted summary judgment holding claims 1 and 9 invalid for obviousness over multiple prior-art patents and alternatively held claim 9 not infringed; it also dismissed non-patent claims. ZUP appealed.
- On appeal, the Federal Circuit affirmed invalidity of claims 1 and 9 as obvious, concluding prior art disclosed the claimed elements, a person of ordinary skill would be motivated to combine them to improve rider stability, and ZUP’s secondary-indicia evidence (long-felt need, copying, commercial success) was insufficient to create a genuine dispute. The court did not reach infringement.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Are claims 1 and 9 invalid as obvious under pre-AIA 35 U.S.C. § 103(a)? | ZUP: claimed combination is novel; prior art does not suggest using handles and foot bindings simultaneously as claimed; secondary considerations show nonobviousness. | Nash: all claim elements existed in prior art and industry motivation (rider stability) provided reason to combine; secondary indicia are weak. | Affirmed: claims 1 and 9 invalid as obvious; motivation to combine found and secondary evidence insufficient. |
| Did the district court improperly shift burden on secondary considerations? | ZUP: district court shifted burden by demanding proof of long-felt need and other indicia despite challenger having burden of persuasion. | Nash: patentee bears burden of production on secondary considerations; challenger retains burden of persuasion for invalidity. | Rejected ZUP's claim of burden-shifting; court correctly treated secondary-indicia production burden on patentee while keeping ultimate persuasion with challenger. |
| Was evidence of copying sufficient to create a factual dispute? | ZUP: Nash obtained a ZUP sample and then produced a board that resembled the ZUP Board, indicating copying. | Nash: resemblance requires a user to ignore Nash’s instructions; no direct blueprint or internal documents show replication. | Held: copying evidence weak; not enough to defeat summary judgment. |
| Should the court decide infringement of claim 9 after invalidity ruling? | ZUP: (implicit) infringement analysis would matter if claims valid. | Nash: district court alternatively found no infringement. | Not reached on appeal because patent claims were held invalid. |
