Legal subjectivity:
Minors can apply for patents. Restrictions on patent applicants under my country's relevant laws include that Chinese entities or individuals apply on their own, and foreigners and foreign enterprises without regular residence or business offices in China should entrust a patent agency established in accordance with the law to apply. There is no age limit for natural persons. Legal objectivity:
Article 18 of the Patent Law: Foreigners, foreign enterprises or other foreign organizations that do not have a habitual residence or business office in China shall apply for patents and handle other patent affairs in China. The established patent agency handles the matter. Chinese entities or individuals that apply for patents and handle other patent matters domestically may entrust a patent agency established in accordance with the law to handle them. Patent agencies shall abide by laws and administrative regulations and handle patent applications or other patent matters as entrusted by the principal; they shall be responsible for keeping confidential the contents of the principal's inventions and creations, except where the patent application has been published or announced.
