If you know the patent name, you need to check the patent number. It's a U.S. patent.

You can search for patents on the website of the United States Patent and Trademark Office (USPTO). Enter USPTO in Baidu to find the website.

It should be noted that what you provided is a trademark name, and there is no corresponding relationship between the trademark name and the patent. Therefore, it is not feasible to search directly using the trademark name. You can use SERTA to search. The company has only a few dozen patents in the United States, including some designs. You can find the patents you need by looking at them one by one.
