Filing requirements in China

Chinese is the official language. If the patent application is in any other language, then its translation must be submitted at the time of its filing. The late filing does not exist in China 

It is necessary to provide the CNIPA with the applicant and inventor details and application materials to obtain the filing date.

The person should submit the POA at the time of Patent filing or within three months from receiving the corresponding notification from the Patent Office.

If the Priority Document is in any other language, the deadline to submit the English translation of the priority document is likely three months from the earliest priority date claimed.

It is not important to provide the Assignment Deed between the inventor(s) and applicant(s) when filing a patent application.

Examination of a Chinese patent application

In China, Patent applications undergo formal and substantive considerations. The request for a substantive review of a patent application in China must be made within three years from the priority date.

Novelty grace period

As per the Chinese legislation, the patent office does not disapprove the novelty of the invention disclosed within six months prior to filing if:

– it’s disclosed by any person without the knowledge of the applicant.

– it’s first exhibited at an international exhibition authorized by the Chinese Government.

– it’s first made public at a prescribed conference or technological meeting.

The validity of a patent in China is 20 years from the date of filing. At the time of registration, the first annual fee, as well as stamp tax for the patent certificate and publication fee, is paid. The subsequent annual fees should be paid in advance before the expiry of its international filing date. Late payment can be made within a six-month grace period by paying a corresponding additional charge.
