Finally, Baidu is launching its patent search services in China that called Baidu Zhuanli. In my previous post, I’ve briefly introduced this service, that is a joint-product cooperated with the SIPO, State Intellectual Property Office of the P.R.C.

When you type some keywords to this patent search engine, the relevant results will appeared on the Baidu page. Click on any hyperlink on the page will bring you to the patent (in Chinese), however in contrast to Google’s Patent Search, Baidu Zhuanli does not offer any document related to the patent that can be viewed in PDF format. You will only get a brief information about the patent and is meant to be barely viewed through a browser interface, such as patent number, filing date, issue date, inventor, inventor’s address, and patent classified number, as shown in the below picture.

In response to the needs of the potential users, Baidu Patent Search is integrated with a whopping patent database which amounted to 2.7 million of China’s patents.
