When applying for an invention patent, we generally recommend that customers apply for a utility model patent and an invention patent together, because the review and certification time for a utility model patent is faster than that for an invention patent. This has Conducive to the protection of product patents. However, it does not mean that after the utility model patent is authorized and certified, the invention patent will definitely be approved. This still depends on the technical aspects of your product. As long as the invention technology of your product is good, there is basically no problem in obtaining an invention patent authorization.
