Trademark Similarity: Judicial Findings in Context

Compare the marks' appearance, sound and meaning in light of how ordinary consumers and traders perceive them. The central question is whether their use may cause confusion about the source of the goods.

2005 Heo 8159 Trademark registration invalidation
[Legal]
  1. Trademark similarity is assessed as a whole, objectively and at separate times, considering appearance, pronunciation, concept and the likelihood of source confusion. Naturally separable dominant elements may be considered.
  2. Goods and services are compared by their relationship, providers, purposes, sales locations and consumers, and whether use of similar marks could create an assumption of common source.

[Similarity of the marks]
The service mark at issue:Illustration: Trademark Similarity: Judicial Findings in Contextcombines three gem-shaped graphics with SAMSUNG, GEMOLOGICAL LABORATORY and SGL on three lines. These elements are separable. GEMOLOGICAL LABORATORY is descriptive of the appraisal services, allowing identification by SAMSUNG or SGL. When identified by SAMSUNG, the mark shares the earlier marks' pronunciation and concept and is similar overall.
[Similarity of goods and services]
Gem grading evaluates the quality of gemstones. Appraisal and jewelry sales commonly share businesses, premises and consumers, creating a close relationship between the services and the goods.
[Decisions]
The marks and their respective goods and services were similar. The service registration therefore fell under former Article 7(1)(7) and was subject to invalidation under Article 71(1)(1) of the Trademark Act.
