The Taiwan Trade Mark Act stipulates that any mark identical with or similar to a mark registered or filed earlier by another shall be unregistrable. In assessing whether a junior mark is similar to a senior mark, the two marks are generally viewed in their entireties. However, in a recent opposition case, questions have arisen as to whether a junior mark incorporating several discrete components respectively similar to a series of senior marks will be deemed a similar mark and whether the form under which a senior mark is used in commerce will be considered in the assessment of likelihood of confusion.
