The US Court of Appeals for the Federal Circuit upheld the Trademark Trial & Appeal Board’s refusal to register a mark due to the “close similarity” between the applied-for mark and a previously registered mark. In Re: Charger Ventures LLC, Case No. 22-1094 (Fed. Cir. Apr. 13, 2023) (Prost, Reyna, Stark, JJ.)

Charger Ventures applied to register SPARK LIVING, identifying its services as rental property management and real estate leasing and listing. Based on an existing mark, SPARK, which identified other real estate services such as rental brokerage, commercial property leasing and management, the Examining Attorney ultimately refused to register Charger’s mark, despite Charger twice amending its application and disclaiming the word LIVING. Charger appealed to the Board, which used the 13 DuPont factors to analyze likelihood of confusion. The Board focused on five of the DuPont factors:

  1. Similarity of the marks: SPARK LIVING fully incorporates SPARK, and LIVING is both descriptive and disclaimed, making it “subordinate to SPARK.”
  2. Similarity of the nature of goods/services: While not identical, commercial and residential real estate services may “emanate from a single source under a single mark.”
  3. Similarity of trade channels: There exists “some overlap” between commercial and residential real estate trade channels.
  4. Class of purchasers: Although real estate purchasers exercise a high level of care, “even . . . sophisticated purchasers are not immune from source confusion.”
  5. Strength of the mark: Although SPARK is somewhat commercially weak, “even weak marks are entitled to protection.”

The Board did not announce the weight it afforded to each factor but found that Charger failed to overcome the high similarity between its mark and SPARK. The Board therefore affirmed the Examining Attorney and refused to register SPARK LIVING. Charger appealed to the Federal Circuit.

As to factor 1, Charger argued that the Board erred in finding similarity of the marks. The Federal Circuit disagreed, noting that Charger disclaimed LIVING from its mark. The Court explained that disclaimer has no legal effect on likelihood of confusion because consumers do not know which words have been disclaimed. The Court found that the Board properly considered the full mark and that the marks were clearly similar.

As to factors 2 and 3, Charger argued that the previous SPARK registration could not be newly extended to include residential real estate services. The Federal Circuit rejected Charger’s argument, finding that many marks bridge the commercial and residential gap and that a registration’s listed services do not limit the trade channels in which the mark actually operates.

Regarding factor 4, Charger argued that SPARK and SPARK LIVING appealed to different classes of purchasers. The Federal Circuit disagreed, finding that Charger had failed to show that residential property owners were distinct from commercial owners.

Charger asserted that the Board improperly analyzed factor 5, since a mark’s weakness is “paramount” to likelihood of confusion. However, the Federal Circuit agreed with the Board that Charger failed to overcome the registered mark’s presumption of validity, despite other “spark” marks in the field. The Court [...]
