Robots involve more than just a patent. First of all, there is an invention patent, which is the core operation of the robot, which embodies the intelligence on the one hand. These technologies can be patented for invention.
At the same time, robots also involve appearance patents, because robots must have a unique appearance, and for the appearance of robots, they must apply for the protection of appearance patents.
At the same time, intelligent robots definitely involve some practicality. For example, some robots specialize in washing dishes, some specialize in sweeping the floor, and they are also practical. For the innovation of practical technology, it is necessary to apply for a utility model patent to protect it.
