Question:
We understand that the file wrapper of a Chinese patent application can be searched through the China Patent Inquiry System (http://publicquery.sipo.gov.cn/). Could a case proceeding under the Patent Prosecution Highway (PPH) before SIPO also be searched through this system?
Answer:
The system does not provide access to view or download image file wrappers for PPH cases. Therefore, the file wrapper of a PPH case cannot be obtained through the system.
