SoClean Prevails in Preliminary Injunction against Sunset Healthcare Solutions

The U.S. Court of Appeals for the Federal Circuit affirms district court’s grant of a narrowly-tailored preliminary injunction in trademark infringement case brought by SoClean, Inc., a medical device company that makes CPAP machines, against Sunset Healthcare Solutions, Inc. SoClean, Inc. v. Sunset Healthcare Solutions, Inc., No. 21-2311 (Fed. Cir. 2022)

The district court had granted SoClean’s motion for a preliminary injunction on trademark infringement grounds. Sunset argued that the district court had abused its discretion in granting the preliminary injunction because SoClean did not introduce sufficient evidence to support a finding of infringement.

SoClean sued Sunset for patent and trademark infringement after Sunset decided to enter the market for CPAP machines using its own brand. SoClean alleged that its mark had acquired a secondary meaning and that Sunset’s use of its own mark caused confusion in the marketplace. Sunset acknowledged that SoClean had obtained a trademark registration and argued that the mark was invalid because it lacked any arbitrary elements.

The district court concluded that SoClean had presented prima facie evidence of infringement, noting that despite Sunset’s “contentions as to the mark’s validity, trademark registration is prima facie evidence of a valid claim.” The district court also found that SoClean had introduced sufficient evidence of consumer confusion, and enjoined Sunset from continuing to use its brand in connection with sales of CPAP machines.

Preliminary Injunction

On appeal, the Federal Circuit affirmed the district court’s grant of a preliminary injunction. The Court noted that it is well-settled that a plaintiff must demonstrate “a likelihood of success on the merits and irreparable harm” in order to obtain such an injunction. The Court held that SoClean had met its burden of proof, noting that while a plaintiff must meet “vigorous evidentiary requirements” to demonstrate that its mark has obtained secondary meaning and is thus protectable, SoClean had done so. The Court further held that the district court did not err in finding that Sunset’s use of its own brand may cause confusion in the marketplace, and noted that its argument as to the validity of SoClean’s mark fails because it had “failed to introduce sufficient evidence” to challenge the trademark examiner’s decision. Finally, the Court rejected Sunset’s contentions that certain elements of SoClean’s trade dress were functional, noting that Sunshine failed to introduce any direct evidence to support its argument.

Accordingly, the Court held that the district court did not abuse its discretion in granting SoClean’s motion for a preliminary injunction against Sunset on trademark infringement grounds. This decision affirms that medical device companies are entitled to protection of their trademarks and trade dress when they demonstrate a likelihood of success in proving trademark infringement.

Precedents for Future Legislation

The Court’s decision in SoClean v. Sunset Healthcare Solutions provides important precedent for future trademark infringement litigation involving medical device companies. The decision reinforces the importance of protecting trademarks and trade dress, particularly in cases where a plaintiff has demonstrated that its mark has acquired secondary meaning and that there is a likelihood of consumer confusion. This holds true even when a defendant challenges the validity of a plaintiff’s mark. Additionally, the Court’s holding that a defendant must introduce direct evidence to support its contention that certain elements of trade dress are functional serves as an important reminder for medical device companies who wish to protect their trademarks from infringement.

This decision is likely to have significant implications for medical device companies and their efforts to protect their trademarks. Medical device companies should be aware of the significant protections they have available under trademark law, as reaffirmed by this decision. Companies should also look to the Court’s reasoning in SoClean v. Sunset Healthcare Solutions when evaluating their own cases involving infringement claims. In doing so, they may be able to protect their important brand and goodwill from infringement.
