Is the failure of utility model patent an abnormal application?

No. There are many reasons why the patent for utility model is not passed, such as the invention or utility model for which the patent is applied is not novel, and there are problems in the specific writing of the submitted patent application documents. We can not only judge whether it is an abnormal application in turn, but also look at it according to the actual situation. Patent literally refers to exclusive rights and interests. The word "patent" comes from Latin, which means open letters or open documents. It is a certificate used by medieval monarchs to issue certain privileges, and later refers to the exclusive right certificate signed by the British king himself.
