Why this matter warrants attention
The Registrar of Trademarks issued a warning to the Requesting Party regarding the inclusion of inaccurate case law citations in written representations. The Registrar noted these errors could stem from a failure to verify generative AI outputs and stated that such conduct wastes resources and could result in cost awards in future proceedings.
Misrepresented: Case Law | Requesting Party cited Burke‑Robertson v Carhartt Canada Ltd (1994), but Board found the decision did not stand for the principle relied upon. || Misrepresented: Case Law | Requesting Party cited Shapiro Cohen Andrews & Finlayson v 1089751 Ontario Limited (2003), but Board found the decision did not stand for the principle relied upon. || Misrepresented: Other | Board observed multiple inaccurate citations in the Requesting Party's written representations and noted these could result from failure to verify generative AI outputs.
Misrepresented precedent is treated the same as fabricated citations; re-read every case you cite, do not just trust AI summaries.

What this record does—and does not—establish
The Registrar identified the potential source of errors as generative AI.
Retained unchanged after audit: the existing summary is source-specific, non-placeholder, and supported by the recorded source link. Read the underlying source before relying on it for legal advice or a filing.

Controls suggested by the public record
- Verify each cited authority, quotation, and proposition against the underlying source before filing.
- Do not treat a paid legal-research product as a substitute for source verification.
