In practice, if a trademark applicant fails to accurately assess the degree of similarity between a proposed mark and a prior mark, the application is highly likely to be rejected or opposed. It is therefore necessary, within a framework of normative interpretation, to conduct a systematic analysis of the standards, methodologies, and relevant factors for determining whether trademarks are identical or similar.
This article proceeds on the premise that the goods or services designated for use by the disputed mark are identical or similar to those covered by the prior mark. On this basis, the discussion focuses solely on whether the trademarks themselves constitute identical or similar signs.
- Principles for Determining Trademark Identity or Similarity
According to the Trademark Examination and Adjudication Guidelines, the determination of whether trademarks are identical or similar shall be conducted through a comprehensive analysis of the mark’s “form, pronunciation, and meaning,” as well as its overall presentation. The assessment shall be based on the general level of attention and cognitive ability of the relevant public. At the same time, factors such as the distinctiveness of the mark and the reputation of the prior mark shall be taken into account in determining whether confusion as to the source of goods or services is likely to arise. On this basis, three fundamental principles may be distilled.
(1) The Principle of Overall Assessment
A trademark functions as an indicator of the source of goods or services, and its distinctiveness is reflected in the overall visual or aural impression it conveys. Accordingly, the assessment of similarity shall be conducted on the basis of an overall observation rather than through mechanical dissection of the constituent elements of the mark.
(2) The Standard of the Relevant Public
The benchmark for determination shall be the general level of attention of the relevant public, rather than that of professionals or exceptionally careful observers. The relevant public typically includes consumers of the goods or services concerned as well as business operators within the relevant trade.
(3) The Likelihood of Confusion Principle
The ultimate inquiry in determining trademark similarity lies in whether there exists a likelihood of confusion. Where the overall impression of two marks is such that the relevant public may mistakenly believe that the goods or services originate from the same undertaking or from economically linked undertakings, the marks may be deemed similar.
- Methods for Determining Trademark Identity or Similarity
From a technical examination perspective, three principal methods are commonly employed in practice.
- The Separate Observation Method
Under this method, the two marks are examined independently in order to simulate real market conditions. Consumers do not typically compare two marks side by side; rather, they encounter them at different times and in different contexts. The assessment should therefore approximate actual commercial circumstances.
- The Overall Comparison Method
This method emphasizes a comprehensive evaluation of the overall structure, appearance, and composition of the marks. Even where certain differences exist, the marks may still be considered similar if their overall impressions are highly alike.
- The Dominant Element Comparison Method
Many trademarks contain distinctive or core identifying elements. Where such dominant elements are identical or highly similar in two marks, similarity may be found notwithstanding certain differences in their overall composition.
- Specific Factors in Assessing Trademark Similarity
In addition to the above principles and methods, the assessment of trademark similarity requires a comprehensive evaluation of the following factors.
- Distinctiveness of the Prior Mark
The stronger the distinctiveness of a prior mark, the more pronounced its source-identifying function and the broader the scope of protection it is likely to enjoy. Marks with high inherent distinctiveness, or those that have acquired distinctiveness through use, are more likely to give rise to a finding of similarity when confronted with later marks.
- Reputation of the Prior Mark
The higher the reputation of a prior mark, the more sensitive the relevant public will be in identifying its source, and the more readily associations may arise from similar signs. Well-known marks therefore typically enjoy a stronger exclusivity.
- Degree of Attention of the Relevant Public
The level of attention exercised by the relevant public may vary depending on the price, purchasing channels, and frequency of purchase of the goods or services concerned. Generally, consumers exercise a higher degree of attention when purchasing expensive or specialized goods, and are therefore better able to distinguish differences between marks. In contrast, for everyday consumer goods, the degree of attention is relatively lower, and confusion is more likely to occur.
In summary, the determination of whether trademarks are identical or similar is, in essence, a comprehensive evaluation centered on the likelihood of confusion. It involves not only a technical comparison of the constituent elements of the marks, but also an analysis of consumer perception and cognitive processes.
