The State Intellectual Property Office of China (SIPO) added a QR code to its published patent, utility model and design documents in January 2014. The QR code replaces the previous bar code, which could be found on the top right-hand corner of the documents since April 2010. When the QR code of a document is scanned with a mobile app, the bibliographic data from SIPO's patent gazette in Chinese language will be displayed on the device. Furthermore, the full document can then also be accessed via a direct link.
