Chinese character trademarks and trademarks composed of the same Chinese characters and pinyin are generally judged to be similar. For example, "Yili is similar to Yili yili". 3. Pinyin trademarks and combination trademarks consisting of the same pinyin plus Chinese characters are generally judged to be similar trademarks. For example, "haier" is similar to Haier haier. 4. Pinyin trademarks and their similar English trademarks will be deemed similar trademarks. "suoni" is similar to "soni". 5. Trademarks consisting of two different Chinese characters plus the same corresponding pinyin combination are generally not considered similar.
