Summary: written with AI from the case record.
What it's about
Its petition argues that the Second Circuit’s approach conflicts with B&B Hardware’s rule that TTAB and infringement cases use the same standard.
The TTAB decides trademark registration disputes, while federal courts can hear trademark infringement cases; the petition asks when those proceedings address the same issue.
Question presented
1. Whether the Second Circuit’s pre-B&B Hardware rule conditioning issue preclusion on a case-by-case comparison of how tribunals apply their respective multifactor tests conflicts with B&B Hardware’s categorical holding that the likelihood-of-confusion standard for registration and infringement under the Lanham Act is the same. 2. Whether the Second Circuit’s new rule—that a marketplace use “narrower” than an unrestricted registration application defeats identity of the issue—conflicts with B&B Hardware’s “included-usages” test.
What happens next
The petition was distributed for the Court’s December 4, 2026 conference. The Court must decide whether to hear it; the conference does not guarantee an order date, and no oral argument or decision date is set.
