Commodity Piwu belongs to the category of 19 in the trademark classification table, and there are indeed a large number of expired trademarks, but

A trademark is different from a patent, but it doesn't mean that it has expired, and it will be invalid without renewal, so anyone can use it, because others may apply for or register similar trademarks, so you should make a comprehensive analysis: is it ok to apply for an expired plywood trademark? If yes, apply for a trademark and use it after registration.

Please ask the questioner to give a detailed introduction before answering.
