TTABlog Test: Is DUNDER MIFFLIN Confusable with MIFFLIN for Paper Products?

The Office [The USPTO, that is] refused to register the proposed mark DUNDER MIFFLIN for various goods in class 16, including gift wrapping paper, paper gift wrapping ribbons, printed greeting cards, and paper party supplies, finding confusion likley with the registered mark MIFFLIN for paper labels and tags” and “plastic ornamental bows for decoration and gift wrapping and other paper products. The Board found the goods to be complementary and related, but what about the marks? How do you think this came out? In re NBCUniversal Media, LLC, Serial No. 97831933 (March 24, 2026)[not precedential] (Opinion by Judge Elizabeth A. Dunn).

The Examining Attorney argued that MIFFLIN (the name of Pennsylvia's first governor) is the dominant word in Applicant NBCUniversal's mark: "MIFFLIN could be seen as a shortened version or reference to DUNDER MIFFLIN. For example, DUNDER could be considered suggestive of dunderhead, which refers to an idiot in colloquial terms and thus act as a modifier to MIFFLIN, evoking humorous buffoonery."

The Board didn't buy it. There was no evidence that DUNDER is a dictionary term or has any descriptive significance vis-a-vis the involved goods. "The record provides no reason to find that the term DUNDER would be perceived as a form of 'dunderhead,' or that the term DUNDER would be perceived as a modifier of MIFFLIN."

Based on its fanciful nature and first position in the mark, we find the term DUNDER is slightly dominant in creating the commercial impression of Applicant’s DUNDER MIFFLIN mark. * * * In fact, we find that the mark DUNDER MIFFLIN creates a different commercial impression than the one created by the mark MIFFLIN alone.

Google search results for DUNDER MIFFLIN uniformly refer to the fictional paper supply company which is the setting for the television show "The Office." An article from Variety states that "The Office" was "by Far the Most-Streamed TV show in 2020," according to Nielsen ratings. Merchandise from Amazon, Peacock Shop, Etsy, and Spencer’s bear the DUNDER MIFFLIN mark and associate the mark with the show.

The Examining Attorney oddly argued that the comparative fame of the involved marks "is not significant” in an ex parte appeal. While that may be true in the abstract, "determining the connotation and overall commercial impression created by the two marks is part of the likelihood of confusion analysis." The Board found the evidence of how the purchasing public encounters the DUNDER MIFFLIN mark to be directly relevant to the assessment of the mark’s connotation and commercial impression. "That the same type of evidence may be considered in connection with fame does not bar its consideration."

The Board also disagreed with the Examining Attorney’s argument that “[A]pplicant has not established the relevant consumer of the applied-for goods would readily recognize the reference of DUNDER MIFFLIN to a fictional paper company associated with The Office.” The Board noted that "[t]he paper labels and tags and paper gift wrap involved here are paper products available to the general consumer. The Office was a television show about a paper company, and originally available to the general consumer on a television network, and, as demonstrated by the article in Variety, subsequently viewed by many more consumers via streaming services."

We find that the fanciful prefatory term DUNDER alters the overall commercial impression created by the term MIFFLIN alone. In addition, we find significant evidence that the connotation of the term DUNDER MIFFLIN to the general consumer of Applicant’s goods is a reference to the setting for the television show “The Office.”

And so, the Board reversed the refusal to register.

TTABlogger comment: I used to watch the original British version of "The Office," when I still liked Ricky Gervais.
