80 F.4th 1363
Fed. Cir.2023Background
- Columbia holds U.S. Design Patent D657,093 claiming the ornamental design of a "heat reflective material" (wavy pattern). Seirus sells "HeatWave" fabric with a similar wavy design and logo.
- District court initially denied claim construction but granted summary judgment of infringement and a $3,018,174 damages award; this court vacated that summary judgment in Columbia I and remanded.
- On remand the district court limited admissible comparison prior art to "wave patterns on fabric," admitted Boorn, Respess, and Blauer, and precluded Columbia from arguing those references do not disclose "heat reflective material."
- At the infringement trial the court instructed the jury with the ordinary-observer test but did not (a) define the proper scope of comparison prior art as requiring the prior designs be applied to the same article of manufacture, or (b) state expressly that source confusion/likelihood of confusion is irrelevant to design-patent infringement.
- The jury returned a verdict of non-infringement. On appeal the Federal Circuit vacated the non-infringement judgment and remanded because the jury instructions failed to provide the correct legal standard for qualifying comparison prior art; the court upheld the district court’s instructions regarding logos/confusion and declined to decide damages issues.
Issues
| Issue | Plaintiff's Argument (Columbia) | Defendant's Argument (Seirus) | Held |
|---|---|---|---|
| Scope of comparison prior art: what qualifies | Comparison prior art must be limited to designs applied to the same article of manufacture (i.e., heat reflective materials) | Scope may be broader; prior art need only be "close" or similar wave patterns on fabric | To qualify as comparison prior art the prior design must be applied to the article of manufacture identified in the claim (same-article requirement) |
| Jury instruction re comparison prior art | Court should have instructed jury on the same-article standard and allowed Columbia to argue Boorn/Respess/Blauer do not disclose heat-reflective material | No error; admission and instruction were adequate; prior appellate posture excuses no further explanation | Failure to instruct on the legal standard for comparison prior art was prejudicial error; vacated non-infringement and remanded for further proceedings |
| Role of logos/source confusion in design-patent analysis | Jury should be told consumer-source confusion (and likelihood of confusion) is irrelevant; logos may be considered only as one design feature | Ordinary-observer instruction (as given) suffices; logos can be considered among design differences | Court affirmed that actual source confusion is not required but that the district court did not err in declining to add plaintiff’s requested clarifications; logos may be considered as one among other differences |
| Preclusive effects of prior proceedings / judicial estoppel / forfeiture | Columbia argued earlier rulings limited what prior art counts; Seirus argued Columbia forfeited claim construction and should be estopped from arguing a narrow article definition | Both parties invoked law-of-the-case/forfeiture/estoppel to bar the other; Seirus urged vacatur deprives prior rulings of preclusive effect | Court rejected law-of-the-case and judicial-estoppel bars here and exercised discretion to address issues fresh on remand; forfeiture arguments did not preclude reexamination of prior-art scope |
