Businesses often assume that trademark conflicts arise only when two companies sell the same or similar products. A recent Supreme Court decision serves as an important reminder that well-known brands may enjoy protection that extends well beyond the specific goods or industries for which they are recognized.
In ISCO Holding Corporation v. Nikon Corporation (G.R. No. 256002, November 17, 2025), the Supreme Court upheld the denial of ISCO’s application to register the mark “NIKON” together with an anchor design for use on household appliances, despite the fact that Nikon Corporation is primarily known for cameras and imaging products. The Court found that Nikon had sufficiently established the worldwide recognition of its trademark through extensive registrations, global use, sustained marketing efforts, and prior recognition by Philippine intellectual property authorities, entitling it to broader protection than an ordinary trademark would receive. Applying the Dominancy Test, the Court further found that the word “NIKON” remained the dominant element of ISCO’s mark, and that the additional anchor design and color variations were insufficient to distinguish it from the well-known one.
The decision also clarifies an important principle under the Intellectual Property Code. Where a mark has attained well-known status and is registered in the Philippines, its protection is not confined to identical or closely related products. Registration may still be refused even where the competing goods belong to an entirely different category, if the use of the mark suggests a connection with the well-known brand or is likely to prejudice its interests.
For businesses, the ruling is a practical reminder that trademark conflicts are not limited to competing industries. A proposed mark that resembles a globally recognized brand may face opposition and denial regardless of the products involved, and the costs of getting it wrong, failed registration, legal disputes, and forced rebranding can far outweigh the time and effort of conducting proper trademark due diligence at the outset. Before committing to a name or brand identity, seeking legal advice early in the process is the most effective way to avoid these pitfalls.
