Who should be the author of the title patent?

basically useless. It depends on which province it is from, and whether it is public or non-public (the requirements for non-public are lower). Many provincial utility models are useless even by the first author (I have 17 items). The general requirement is that the invention patent is useful. It is recommended to check the specific provisions of the professional title documents of this province (generally available in official website, the Department of Human Resources and Social Security of the province).
