What kind of patent does your mop have? In terms of appearance, if someone else applies for a patent on the mop head alone, then yours is also infringing. As long as the appearance patent is not exactly the same, it is difficult to determine it as infringement. If you sell online, if someone complains about you, you may be asked to provide evidence of this. If you sell a lot, you can also apply for a design patent for this single product.
