I uploaded invention and utility model electronic patent offline applications at the same time on the same day. I only received invention and utility model approval, invention acceptance and payment notices, but I did not receive utility model acceptance and payment notices. Consult the State Intellectual Property Office 010 62356655 3 1 Manual reply: This phenomenon is caused by an abnormality in the gateway server of the Intellectual Property Office. Let the utility model receive the case number: xxxxxxxxx nine digits, which will take 2-3 working days to resolve. Asked if it was because the invention and utility model files were uploaded at the same time that it was difficult for the Intellectual Property Office's gateway server to recognize the abnormality, the answer was no. However, I considered uploading it separately in the future. After uploading the invention, upload the utility model immediately, because this kind of problem did not occur when another patent was uploaded separately last time. It is difficult to get through the manual phone number of Guozhi. There are millions of patent inventors in the country and all kinds of problems. It is understandable that it is difficult to understand a customer service phone number.
