Trademark Registration: Similarity and Consumer Confusion in Electronic Goods

The Supreme Court's 2015 decision in Taiwan Kolin Corporation, Ltd. v. Kolin Electronics Co., Inc. (G.R. No. 209843) clarifies a key question in Philippine trademark law: when can two companies use the same mark on different products? The case involved two companies both using mark, covering goods that included television sets and DVD players under Class 9 of the Nice Classification. Kolin Electronics Co., Inc. opposed the application, claiming it had already registered the "KOLIN" mark in 2003 for its own Class 9 products—automatic voltage regulators, converters, rechargers, stereo boosters, AC-DC regulated power supplies, step-down transformers, and PA amplified AC-DC devices.

The two companies had a history of disputes over the for trademark purposes. Citing the doctrine in Mighty Corporation v. E. & J. Gallo Winery, the Court listed several factors to consider in determining whether goods are related:

• The business to which the goods belong
• The class of product
• The product's quality, quantity, or size
• The nature and cost of the articles
• The descriptive properties and physical characteristics
• The purpose of the goods
• Whether the article is bought for immediate consumption
• The fields of manufacture
• The conditions under which the article is usually purchased
• The channels of trade

Applying these factors, the Court found that Taiwan Kolin's television sets and DVD players were home appliances with distinct functions, while Kolin Electronics' products were power supply and audio equipment accessories. The goods flowed through different channels of trade—Taiwan Kolin sold wholesale to accredited dealers, while Kolin Electronics' products went through electrical and hardware stores.

The Ordinary Intelligent Buyer Standard

The Court also applied the "ordinary intelligent buyer" standard rather than the "completely unwary consumer" test. Because televisions and DVD players are relatively expensive, luxury items not purchased frequently, buyers are expected to be more cautious and discriminating. As the Court noted in Del Monte Corporation v. Court of Appeals, a person who buys an expensive item exercises more care than one buying a low-priced article.

The Court further observed that the two marks, while both using the word "KOLIN," had visual differences—Kolin Electronics' mark was italicized and black, while Taiwan Kolin's was white on a red background. These differences, though subtle, were sufficient to distinguish one brand from another for the ordinarily intelligent buyer.

Practical Takeaways

• Same Nice Classification is not decisive. Products falling under the same class do not automatically qualify as "closely related" goods for trademark opposition purposes.
• Product relatedness requires a multi-factor analysis. Courts will examine the nature, purpose, cost, and channels of trade of the goods, not just their classification.
• The "ordinary intelligent buyer" standard applies to expensive goods. For costly, infrequently purchased items, courts presume consumers exercise greater care and are less likely to be confused.
• Visual differences matter. Even subtle differences in a mark's presentation—such as font style or color—can prevent a finding of confusing similarity.
• Business context is crucial. Where parties operate in different market segments and distribution channels, the risk of consumer confusion diminishes significantly.
