Is it a violation to submit papers early for the Patent Office exam?

Doesn’t count. Hand in, a Chinese word whose pinyin is jiāojuàn, means that the person taking the exam hands over the completed test paper; it is a metaphor for completing the accepted task. It is not a disciplinary violation for a candidate to submit papers in advance within the stipulated time, but it is a disciplinary violation to submit papers in advance beyond the stipulated time. The State Intellectual Property Office (Patent Office) is directly under the State Council and is a national administrative institution. Its regular employees are civil servants. The State Intellectual Property Office is a national bureau managed by ministries and commissions of the State Council, managed by the State Administration for Market Regulation, and its administrative level is deputy ministerial level. The bureau is responsible for protecting intellectual property rights, promoting the construction of the intellectual property protection system, responsible for the registration and administrative adjudication of trademarks, patents, and geographical indications of origin, and guiding trademark and patent law enforcement.
