Hello!
When searching for trademarks and patents on the website of the State Administration for Industry and Commerce, the information is quite lagging behind. Especially in the past two years, the website system of the Administration for Industry and Commerce seems to have been being upgraded and modified, but the problem has not been solved.
As for your situation, you don’t have to worry. The current trademarks and patents are basically like this. They have been notified and cannot be found online. This is normal and you can rest assured.
