Patent amendment period

Legal analysis: the time limit for patent correction is determined by the notice of correction. If the notice of correction is presumed, the date of receipt is presumed to be fifteen days from the date when the document is issued by the Patent Office (this date is recorded in the notice and decision), so the time limit for reply is the notice time plus 15 days.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it.

A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
