What patent is your mop? Appearance, if someone else alone applied for a patent for mop head, then this is also infringement. As long as the appearance patents are not exactly the same, it is difficult to judge as infringement. If you sell online, others may complain about you, and you may be asked to provide evidence in this regard. If you sell a lot, you can also apply for an appearance patent for this.
