The impact of product relevance—the stronger the product relevance, the higher the risk of infringement. However, it is often easy to overlook this aspect during the inquiry and evaluation process. For example, when judging infringement, the correlation with the goods designated by the prior trademark is not fully considered, and only the degree of similarity of the marks is judged without distinction. Specifically, regardless of whether the products are exactly the same or similar according to the differentiation table, the risk is still considered high even when certain key groups of products have been rejected. If the products are the same according to the differentiation table, you need to be more cautious when making judgments. In addition, the determination of similarity of goods in trademark infringement cases involves case-by-case determination and some subjective judgment factors, which require a comprehensive assessment based on the degree of relevance of the goods themselves and prior cases.
