National patent refers to three forms of invention and creation that can be protected by patent law: invention patent, utility model patent and design patent, among which invention patent is the most important one.
To apply for a patent for invention, the application documents shall include: the request for a patent for invention, the specification (if there are drawings in the specification, the drawings in the specification shall be submitted), the patent claim and the abstract (if necessary, the drawings shall be included in the abstract) in duplicate.
To apply for a patent, the necessary application documents shall be submitted and the fees shall be paid in accordance with the regulations. Patent applications must be handled in written form or electronic application form. Written application documents cannot be replaced by oral explanations or samples or models. In the patent examination and approval procedure, only written documents have legal effect.
If the formalities need to be accompanied by supporting documents or attachments, the supporting documents and attachments shall be originals or photocopies, and photocopies shall not be used. If there is only one original, you can use a copy, but at the same time you need to attach a certificate that the copy issued by the notary office is consistent with the original.
