This issue is more complicated and needs to be analyzed based on the specific situation. Generally speaking, applying for a registered trademark should follow the principle of on-demand application, that is, apply for trademark rights in the categories of goods and services involved in or related to the business scope. If you arbitrarily register a trademark in a category that has no possibility of use, you may face cancellation after not using it for three consecutive years without justifiable reasons.

However, if the brand already has a high reputation, or the newly launched brand itself has high social attention, then in order to avoid others rushing to register your trademark in other categories, at the same time In order to prevent the trademark from being diluted and vilified (such as using Chanel on toilet cleaners), the scope of defense should be expanded when applying for a trademark, so as to ensure that the unique correspondence between the brand and the merchant is not destroyed. If necessary, you can apply for all categories.
