Patent Protection in China

A patent is an exclusive right granted for a product or a process that provides a new way of doing something, or offers a new technical solution to a problem. The patented invention cannot be commercially made, used, distributed or sold without the owner’s consent. In order to obtain patent protection in China, the owner of the invention has to file a Chinese patent application. The Chinese State Intellectual Property Office (SIPO) is the government authority that examines and grants patent applications. There are three types of patents: (1) invention patents, (2) utility model patents, and (3) design patents. Invention patents are examined, while utility model patents are subject to a formal examination. A European registered patent has no legal effect in China

Steps to apply for patent protection in China

1. Provisional Patent Application
The first step is to file a South African provisional patent application for your invention. This is done to obtain the earliest possible date from which to claim rights to your invention for 12 months. Filing a South African provisional patent application that adequately describes the invention will establish priority and satisfies the need to act swiftly under first to file rules. Ultimately you will need to file a Complete patent application in order to obtain a patent in China.

2. PCT
South African residents can file a PCT application within the 12-month period from the filing date of their provisional patent application. The PCT procedure is valid for 18 months and maintains your priority date in all 145 contracting states (including China). National Phase: At the end of the PCT procedure (usually at 30 months from the earliest filing date) you can file a complete patent application with the State Intellectual Property Office of China (or any other PCT member countries in which you want to obtain protection).

3. Complete Patent Application
File a complete patent application in China, and/or in each country where you wish to obtain patent protection. The complete patent application will claim a first (or “priority”) date from your provisional patent application. In order to obtain a utility patent, a non-provisional application must be filed (because a provisional application will never mature into a patent)

Types of Patents

Patent rights commence from the date of publication of the grant in the Patent Gazette. The duration of the application procedure and term vary depending on the type of patent:

Invention Patent
Granted within 3 to 5 years and valid for 20 years from the date of filing (or the priority date if priority is claimed) subject to the payment of annuity fees.

Utility Model
Granted within one year and valid for 10 years from the date of filing (or the priority date if priority is claimed) subject to the payment of annuity fees.

Design Patent
Granted within one year and valid for 10 years from the date of filing (or the priority date if priority is claimed) subject to the payment of annuity fees (see table below for details).

Patent Requirements

An invention patent must not have been previously published overseas or in China, and must not have been used in China prior to the patent application. When compared to existing products, the invention must have an advantage. If an identical invention has been published before the application date, this will destroy the novelty of the patent.

  • There are specific disclosure requirements (on sufficiency, support, and clarity).
  • Novelty.
  • Industrial applicability.

Patent applications are processed in Chinese. If the patent documents are drafted in a foreign language, a precise Chinese translation of the documents is of the utmost importance.

Patent Exclusions

The Patent Law provides that the following works will not be afforded patent protection: Animal and plant varieties. Anything immoral or detrimental to the public interest. Methods for the diagnosis or for the treatment of diseases. Rules or methods for mental activities. Scientific discoveries. Substances obtained by means of atomic transformation. Software itself cannot be patented, although software combined with a computer or technique intended to solve a technical problem may be. Process inventions can be patented in China.

Patent Search

It is very important for applicants to search for similar inventions before applying for a Patent. A Patent Search will indicate whether your idea or inventions has been patented before. Although novelty can never be determined conclusively, an indication of the novelty of your invention may be found by conducting patent and literature searches on the internet. Patent Attorneys may conduct a search for your Invention, but you may also search for similar patents yourself.
