52 F.4th 1363
Fed. Cir.2022Background
- SoClean, maker of CPAP sanitizing devices, owns U.S. Trademark Registration No. 6,080,195 for the configuration of its replacement filters.
- SoClean sued former distributor Sunset for patent and trademark infringement; the district court consolidated related suits and considered a preliminary-injunction motion by SoClean.
- The district court found SoClean likely to succeed on the trademark claim, invoked the statutory presumption of validity for the registered product configuration, and granted a narrow preliminary injunction requiring Sunset to clearly associate its online marketing and sales with the Sunset brand (e.g., images of the filter cartridge must prominently display the Sunset brand name).
- Sunset appealed, challenging (1) the district court’s treatment of secondary-meaning evidence and the presumption of validity, and (2) the court’s consideration of alternative designs in the functionality analysis.
- The Federal Circuit affirmed: it held the district court properly relied on the registration presumption (any misstatement about the applicable burden was harmless), and it correctly considered alternative designs and other evidence in concluding SoClean was likely to defeat Sunset’s functionality defense.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the district court erred in treating SoClean’s registration as prima facie evidence of secondary meaning | SoClean: registration creates a statutory presumption of validity/secondary meaning, shifting burden to Sunset to rebut | Sunset: court should review the PTO examiner’s actions and not apply the presumption or should require a higher showing from SoClean | Affirmed — registration creates a mandatory presumption of validity; court may not withhold it; any district-court misstatement about the burden was harmless because Sunset’s evidence was equivocal |
| Whether the district court erred by considering availability of alternative designs in the functionality analysis | SoClean: combination of features includes nonfunctional/arbitrary elements; alternative designs support nonfunctionality | Sunset: design is entirely utilitarian; alternative designs should not overcome functionality | Affirmed — court properly considered alternative designs as relevant indirect evidence; district court reasonably found both functional and nonfunctional features and that SoClean was likely to defeat functionality challenge |
