To solve your problem, you must first have a simple understanding of trademarks.

In the case of trademarks, since trademarks protect goods or services, we focus on the three points of trademark name, category, and protected items (trademarks or services).

1. Trademark names are usually in Chinese, English, graphics or a combination of the three. They are easy to understand and will not be discussed here.

2. Categories. Since there are many goods and services in the world, they are classified and summarized into 45 categories, of which categories 1-34 are commodities and 35-45 are services. For example, daily chemicals are in category 3, clothing is in category 25, and catering is in category 43. Among them, lamps are in category 11.

3. Protection projects. In each category, there are thousands of various product names. For example, in category 11, there are car lights, household lights, electric lamps, incandescent lamps and other products, among others , and some small household appliances are also in category 11. Generally, you can select 10 products for protection, or more than 10.

When registering a trademark, you register the trademark name in the corresponding category, and select the product name you want to protect in the corresponding category. These three most important pieces of information will also be on the trademark certificate.

Going back to your question, you can look at the other party’s trademark certificate to see how many categories it authorizes you and what specific products it is.
