Recent Development

China’s National Intellectual Property Administration (CNIPA), formerly known as the State Intellectual Property Office (SIPO), has been making significant strides in bolstering its patent and trademark framework. The recent implementation of the Fourth Amendment to the Patent Law has introduced noteworthy changes, with new provisions aimed at strengthening enforcement mechanisms, optimizing IP services, and promoting the commercialization of innovations. This development is a testament to China’s commitment to creating a more robust and transparent IP ecosystem, positioning itself as a key player in the global IP landscape.

The Patent Search Process

Embarking on a patent search in China requires a thorough understanding of the country’s unique legal framework and a methodical approach to navigating its vast databases. The CNIPA provides online access to its patent databases, allowing users to search for patents, utility models, industrial designs, and trademarks. However, the language barrier and the sheer volume of the available information may prove challenging for those unfamiliar with the Chinese legal and patent systems.

To overcome these hurdles, it is crucial to engage the services of a local patent attorney or a professional patent search firm with in-depth knowledge of the Chinese IP landscape. These professionals can guide you through the process, ensuring that your search is comprehensive and tailored to your specific needs.

Filing Requirements in China

Chinese is the official language of China. The application must be translated into Chinese at the time of submission; late filing is not an option. The Chinese Intellectual Property Administration must be given the information and application documents for the applicant and inventor to receive a filing date.

Within three months of the filing date, the power of attorney must be presented with a simple signed copy.

Within sixteen months of the earliest priority date, a certified copy of the priority document is required. Chinese translations of the priority document’s title are required.

When submitting a patent application, it is not essential to include the assignment deed between the applicant(s) and inventor(s).

Novelty grace period

The publication of knowledge regarding an invention within six months of filing in China does not refute its novelty if:

In the event of a national emergency, the disclosure was made in the public interest; It is initially displayed at an international exhibition that the Chinese government sponsored or recognized; – It is first made public at a specified academic or technological forum; it is revealed by anyone without the applicant’s permission.

Utility Model

Utility model inventions may also be legally protected in China as utility models, which are only subject to official review. A utility model cannot be converted into a patent application, and vice versa. In China, utility models must be given for innovative and useful technical solutions that are appropriate for everyday usage and relate to a product’s design, structure, or combination of these.

In China, a utility model’s maximum patent protection duration is ten years from the date of filing.
