Good morning, I'm glad to answer your questions, the method/step of trademark registration inquiry 1, and open the trademark online inquiry and retrieval system. Open the online trademark query and retrieval system of China Trademark Network in the browser. 2. The function of trademark status query is to query the status of the trademark in the business process through the application/registration number. Enter the trademark registration number to be queried in the "Application/Registration Number" column, such as "10459582". 3. Query and retrieve the record data of trademark license. Click Query to enter the trademark search results page, where you can see the trademark name, application date, application/registration number and the name of the applicant. 4. Check the filing progress of trademark license. You can click "trademark registration number" or "trademark name" to check the registration of the trademark, and then judge whether the registration of the trademark is completed by analyzing the business name link. Analyze the business name "Trademark License Filing", and if the words "Approval Notice Print and Send" are displayed in the link, it means that the trademark license filing has been completed; If this text does not appear, the surface license filing has not been completed. Through this method, you can query the trademark license filing in the online trademark query and retrieval system of China Trademark Network. The food store registration certificate can be found in official website, china food and drug administration. The steps are as follows: Open a computer browser, search for State Food and Drug Administration 2 online, click to enter official website, in the menu bar above official website, click on the food function, and find the food production license-certified enterprise 4 in the menu bar on the left of the query interface. Click on Enter to select the enterprise type you need to query, enter the query keywords, click on Check 5, check the query results in the search results, and click on the results you want to view the detailed information.
