What are the consequences of selling goods with expired patent numbers? The industrial and commercial bureau found a solution.

First, there is no saying that the patent number has expired. Let's just say that the exclusive right is gone. If the patent loses its exclusive right because it is invalid by others, there may be the risk of infringement; If you automatically lose your rights when it expires, it will have no effect.

Second, the Trade and Industry Bureau will not investigate patent-related issues, because this is not within its scope of duties. In terms of intellectual property rights, most people will pay attention to whether a trademark is registered or whether the trademark is used correctly.

Remember to adopt it if it helps.
