The ever-growing flood of Chinese-language patents is causing increasing problems for foreign patent attorneys, corporate research and development teams, and in-house counsel. With traditional patent searches, it is not possible to identify and review all relevant IP rights within an acceptable period of time. Limited keywords do not scan the entire technology breadth and may miss the relationship between keywords as well as synonyms of keywords. In addition, patent descriptions in Chinese bring additional barriers.
This is where AI-powered Chinese patent search tools that can process both Chinese and English come in. They enable foreign patent attorneys and R&D teams to navigate the Chinese patent deluge.
An AI-powered search tool for Chinese patents is a helpful tool for conducting novelty, invalidity, and infringement searches. It can perform an AI search in addition to the traditional semantic search, which converts the natural language representation of the searched technology into the visual representation of a DNA mapping that reveals all the keywords and elements included and the relationships between them.
This visual DNA mapping is compared to DNA mappings of more than 100 million patents from official and commercial sources in 120 countries, previously created by a Deep Learning trained machine and updated weekly. The search tool’s algorithm calculates the similarity between the technology being searched and the patents in the database and displays the results. Because DNA mapping can show the relationships between keywords and elements in the technology descriptions, prior art that uses a similar technology feature structure but uses a different semantic description is not overlooked.
AI-powered search tools for Chinese patents can also provide value-added data. They not only provide the basic patent-related data such as patent litigation, licensing, assignment, pledge, reexamination, or invalidation. The 3D patent sand table can also be used to display the patent layout in a specific industry, highlighting the technologically dense areas and white spots. This can be decidedly helpful in monitoring Chinese competitors.
Given the huge volume of Chinese patent applications, we recommend foreign companies to search Chinese patents using AI-based tools, on the one hand, to circumvent the technological obstacles in the prior art and gain more freedom of practice in China. On the other hand, this enables them to grasp the patent activities of Chinese competitors and make the right decisions in competition.
