The utility model is a utility model. If the invention is not authorized, it has nothing to do with the invention and is still independent and effective. Can continue to maintain.
The utility model is invalid because the invention has passed the examination and needs authorization. Since only one patent right is granted for an invention, you are required to give up your previous utility model patent.
The invention is not authorized, and the utility model is still valid. However, whether the public can invalidate your new patent depends on the purpose of your patent application. If it is only to protect the product, this problem does exist, and your utility model has basically no protection value. At the same time, you should also consider why the invention patent is invalid. If creativity alone is not enough to grant a patent right, then the new model still has the significance of continuing protection. The key is to see the purpose of your patent application. It is good for enterprises to have effective utility model patents.
