As for how many patents to register, it still depends on your actual situation. It is not as simple as one or two. If the purpose of applying for a patent is to promote the company in order to show off, then applying for several applications does not make much difference; if the company wants to obtain complete patent protection for its independent technology, first of all, the device as a whole must apply for a patent, and secondly, the device as a whole must apply for a patent. The more core and creative parts of the equipment should also be applied for separately to obtain comprehensive protection. In addition, patents can be divided into three types: inventions, utility models, and designs. First of all, technical categories should apply for utility models (because utility model approval is faster and the approval rate is high). If the technology has high originality, it should be applied as a utility model. Apply for an invention patent at the same time as a new model (because the invention patent has a longer validity period than a utility model, and after substantive review, the protection is stronger than that of a utility model, but the approval time is longer and the pass rate is lower, so it is necessary to apply for a utility model at the same time to ensure the pass rate , on the other hand, utility models can be used for partial rights protection before the invention patent is approved)
