Can I apply for a new patent for utility model after applying for a patent for invention? Will you apply at the same time?

Yes, if you apply for a patent for invention, you can also request to apply for a utility model, which is referred to as double newspaper for short. Double filing has great advantages. First of all, it should be said that the application for a patent for invention is divided into two stages: preliminary examination and actual examination, and the protection period is longer than 20 years. However, the review is more stringent. As long as there are no major errors in the submitted application and specification format, the utility model patent can be authorized, but the protection period is only 10 years. The purpose of applying for double reporting is to ensure the invalidation of the invention patent authorization. At least one utility model patent can be authorized, and the technology patent is still guaranteed. If the patent is authorized, you can still give up the utility model patent and get the invention patent with long protection period.
