“L@TTITUDE” vs. “LATTITUDE”: How KENFOX Reversed a Refusal & Secured Protection in Vietnam?

Posted by KENFOX IP

in Notable Articles, Trademark

Vietnam is one of ASEAN’s fastest-growing markets – but also one of its most rigorous trademark examination systems, where non-traditional marks face heightened examination, prior cited marks may block registration even with market differences, examiner discretion remains conservative compared to other Madrid members, consent letters are not automatically accepted, stylized, digital-era brand identities (e.g., symbols such as “@”) are often misunderstood under traditional distinctiveness rules A refusal in Vietnam is not merely an administrative hurdle – it...
