UK trademark applications follow international trademark categories, with 45 categories divided into 34 product categories and 11 service categories. The first point is to make sure whether the trademark you are applying for is a product or service category. Look before the 34 categories in the front, and the service category in the last 11. Secondly, you should determine the major categories based on the attributes of the goods or services you are applying for, and determine within the major categories. When looking for smaller categories, you also need to pay attention to some goods or services. The service requires cross-searching when searching.
