Abercrombie & Fitch Trading Co. v 14095863 CANADA INC
Trademarks Opposition Board · Apr 28, 2026
What happened in this matter?
The Registrar of Trademarks found that the pro se Applicant submitted fabricated or irrelevant case law in its written representations, suggesting the undisclosed use of generative AI. The Registrar explicitly declined to rely on these references due to the Applicant's failure to verify its authorities, ultimately resulting in a partial refusal of the trademark application.
- Why the court cared
- The Registrar determined that the Applicant's citations were non-existent or irrelevant, indicating a failure to verify sources despite prior warnings. These issues diminished the reliability of the submissions, leading the Registrar to disregard the cited authorities.
- Why it matters now
- This case illustrates the risks of using generative AI in administrative proceedings without verification. It highlights that even for pro se litigants, there is an affirmative duty to ensure the accuracy of legal submissions, and failure to do so can lead to the disregard of arguments and adverse outcomes.
