Project duration: 6 weeks

Search Language: Japanese and Chinese

Client: A major Europe pharmaceutical company

Field of Technology: pharmaceutical

Brief Description of the Target Patent to be Invalidated: The target patent teaches a polypeptide and applications in treating B cell related autoimmune diseases.

Search strategy:
Full text search

Database used:
For Japanese patents: NRI (for full text search), PATOLIS (for classification search), and IPDL (for downloading full patents for review.
For Japanese non-patent literatures: JDream II (JSTPlus), JSTMedicine
For Chinese patents: CPIN, and SIPO
For Chinese non-patent literatures: CSCD, CNKi, and Wangwei

We were very disappointed that no good art had been uncovered in the searches. Our searches indicate both Japan and China are "inert" in this area.

Thank you kindly for the speedy delivery. I will be sure to advise the client of your remarks regarding the translation. I will also make sure that the reviewer has this information available. I can’t say thank you enough. You have done a great job.
