On May 29, 2026, Lotte Confectionery Co. Ltd. (“Lotte”) prevailed in a trademark opposition against “Custard & device”, convincing Taiwan’s IP Office (“TIPO”) that such contested trademark is too similar to the Lotte’s famous “LOTTE Custard Cake” (i.e., the front view of Lotte’s popular custard cake, see below).
The contested trademark, “Custard & device” (Reg. No. 02262558, see below), was filed by En Maw Trading Co. Ltd. (“En Maw”) on April 29, 2022, and registered on November 16, 2022, covering a variety of goods in Class 30, such as desserts, pastries, cookies, cream puffs, bread, cakes, sponge cakes, cheesecakes, custard pastries, muffins, and pies. Lotte filed opposition on February 15, 2023, citing violation of Articles 30.1.10, 30.1.11, and 30.1.12 of Trademark Act.On May 29, 2026, TIPO ruled in Lotte’s favor, finding that En Maw’s contested trademark should be cancelled for violating Article 30.1.11 of Trademark Act:1. Article 30.1.11 of Trademark Act provides that a mark shall not be registered if such a mark is identical or similar to other’s well-known trademark, and hence may cause confusion among the relevant consumers, or harm the distinctiveness or reputation of such well-known trademark.
2. Based on the extensive sales and marketing records submitted by Lotte between 2018 and 2022, including Nielsen’s sales reports, social media posts, and advertising materials in major local channels such as 7-11, Family Mart, Hi-Life, PX Mart, and Carrefour, TIPO noted that the cited trademark, namely, the front view of Lotte’s “LOTTE Custard Cake” product has become well-known among the consumers due to its popularity in Taiwan.
3. On similarity, TIPO observed that both Lotte’s and EN Maw’s trademarks consist of a white rectangular, red English letter “Custard”, decorative yellow flowers and green leaves, and cut custard cake with visible filling. In the entirety, TIPO found ordinary consumers would find En Maw’s trademark visually similar to Lotte’s “LOTTE Custard Cake”.
4. While En Maw argued that “Custard”, drawings of custard cakes, and decorative yellow flowers are merely descriptive, TIPO reasoned that the combination of all of these elements, together with Lotte’s extensive and continuous use and sales, are sufficient to make image of Lotte’s product distinctive and well-known among the local customers. Besides, there was evidence of consumer’s complaint about the similarity of products, proving the existence of actual confusion.
5. Although En Maw contended that its trademark has been used for more than 20 years and should be distinct enough to co-exist, TIPO disagreed, finding instead that records submitted by En Maw were defective. The lack of actual use of trademark and concrete sales records renders En Maw’s evidence insufficient to prove that its trademark has also been known by the relevant consumers.
In view of the well-known status of Lotte’s “LOTTE Custard Cake”, the similarity between En Maw’s and Lotte’s trademarks, the overlap of product categories, and Lotte’s strong brand recognition, TIPO determined that En Maw’s contested trademark may cause consumer’s confusion. Accordingly, En Maw’s “Custard & Device” mark was cancelled.
