Hello! If the average person suddenly knows that two things are different, it is not infringement; If this is not the case, it may be infringing. Part of the same is not necessarily infringement, it depends on the specific situation. Appearance infringement depends on whether the appearance of that product has applied for an appearance patent. If applied, it will cause infringement. If you don't apply, you can apply.
If the rice mobile phone is completely independently developed, like Xiaomi, the appearance problem should be considered. If it looks like an iPHONE in appearance, I think the rice phone is more inclined to the cottage side. Pure personal opinion, for reference only! ! !
