China: Change of publication day at SIPO

Post by EPO / Asia Info » Wed Nov 29, 2017 4:29 pm

Dear users,

The State Intellectual Property Office (SIPO) has recently changed the frequency and the weekdays for publication of its patents, utility models and designs. As of 6 June 2017, laid-open patent applications, granted patents, registered utility models and designs are published twice a week, on Tuesday and Friday. Legal status information is also released on these days. Previously, SIPO published this information once a week, on Wednesday.

SIPO's official gazettes can either be downloaded as individual PDF files or searched in a database on the Chinese website.

The EPO’s Asian Patent Information Services have just uploaded a new search guide ... earch.html, showing you step-by-step how to retrieve the online gazettes in PDF format. (Click on “Retrieving online gazette issues”). You will find this and other guides on searching Asian databases in the “Searching in databases” section at

For detailed assistance with the retrieval of Asian patent information, feel free to contact

With kind regards,

Your Asian Patent Information Services Team
