Supreme Court rules on trademark claim over the letter 'W'

The Supreme Court has ruled on whether a company can assert ownership and exclusivity over a single letter, in the case of Starwood Hotels & Resorts Worldwide, LLC v. Oceanic Empire Limited, promulgated on Jan. 28. The decision, as reported by BusinessWorld, addresses the dominancy test in trademark opposition proceedings before the Intellectual Property Office.

Starwood Hotels had filed opposition cases with the IPOPHL seeking to prevent Oceanic Empire from registering marks that prominently feature the letter 'W'. The hotel chain argued that the letter, when used in connection with hospitality services, could cause confusion with its own brands. The Court's analysis centered on the dominancy test, which compares the dominant features of competing marks.

In its ruling, the Supreme Court applied a nuanced approach, declining to grant automatic exclusivity over a single letter but weighing the overall commercial impression and likelihood of confusion. The decision provides guidance on how far trademark protection can extend to common characters in the context of the dominancy test.
