According to an official notice, the State Intellectual Property Office (SIPO) has 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.
The existing principle for numbering the issues of the official gazette will be continued. An additional "01" or "02" will be added to the gazette numbers to indicate the different publication day of the corresponding week. SIPO's official gazettes can either be downloaded as individual PDF files or searched in a database on the Chinese website.
