Proposed Tougher Approach to Examination for Utility Model and Design Patent Applications in China

Proposed tougher approach to substantive examination for Utility Model and Design Patent Applications in China.

In a bid to improve the quality of Utility Models and Design Patents granted in China, the Chinese State Intellectual Property Office (SIPO) has put forward proposals to impose tougher examination requirements for Chinese Utility Model and Design Patent applications.

Currently, a design patent (also known as a registered design in Europe) application in China does not undergo substantive examination. This means that, although the Chinese Patent Law requires a design to be new and distinctly different from any one of the existing designs known anywhere in the world, in practise, a Chinese Examiner does not conduct any searching during examination of the design application. Based on the current Examination Guidelines, the Examiner is only required to examine the application based on the application details and what is considered to be common knowledge of a general consumer.

Equally, although a Utility Model (also known as a petty patent in the US or innovation patent in Australia) application is required to be novel, creative and of practical use under the Chinese Patent Law, the level of examination requirement is similarly low.

Considering an Invention Patent application, which is the equivalent of a standard patent available in countries or regions such as the UK, Europe or the US, typically takes around 3 to 6 years to grant, grant of a Utility Model can be obtained relatively quickly, typically between 10 to 18 months. A Design Patent can be even quicker. As such, filing such applications in China has been a faster, cheaper and easier way to obtain patent protection for an invention, compared to an Invention Patent. Both forms of patent protections have been proving popular. In 2011, SIPO granted 408,000 Utility Models and 380,000 Design Patents.

However, this may all be about to change. In a public consultation issued in February 2013, SIPO has indicated that the lack of substantive examination for both types of applications have caused patents to be granted to inventions or designs that are already known, or caused patents to be granted to inventions or designs more than once, i.e. double patenting.

In order to improve the quality of Utility Models and Design Patents, SIPO is proposing to amend the Examination Guidelines such that Examiners are encouraged to conduct searches on existing technologies and designs when examining such applications. Furthermore, the Guidelines proposed to be amended such that Examiners are not restricted as to how such information are obtained.

It is envisaged that if SIPO is to implement its proposed changes to tighten examination procedures for both types of applications, the costs and time required to see such applications through to grant are also likely to increase.

Early indications suggest that SIPO may already be implementing changes and Examiners will be improving enforcement of the novelty requirement for such applications. However, even with tighter examination requirements, for an invention with a short commercial life and somewhat limited novelty, a Utility Model application should still be the favoured choice of patent protection in China.
