Does the doctor of engineering patent have to write in school?

You must write. Patent refers to an invention protected by the patent law, that is, patented technology. Unless otherwise agreed, inventions and other technological achievements made by engineering doctors during their study, further study or cooperative project research in institutions of higher learning shall be owned or held by institutions of higher learning, so it is necessary to specify the school. Patents are proprietary technologies recognized by the state and protected by law on the basis of publicity.
