In respect of PRB's rejection decision, CPA represented the client to initiate an administrative lawsuit, pointing to both substantive and procedural flaws of the decision. In particular about the procedure, CPA's attorneys argued that PRB had cited a new ground not mentioned in the rejection decision of the Patent Office, thereby exceeding the scope of ex-officio examination as stipulated in the Guidelines for Patent Examination. Both the first- and second-instance courts ruled in favour of our arguments and revoked PRB's reexamination decision.
To this, PRB filed a petition to SPC for retrial of the case. Recently SPC has issued its decision and found that it is not justified to extend the interpretation of obvious substantive defect stipulated in the Guidelines to cover inventiveness. Furthermore, with no inventiveness assessment in the rejection decision of the Patent Office and the ground of inventiveness not within the scope of obvious substantive defect, the case is not subject to ex-officio examination by PRB. For these reasons, PRB's request for retrial of the case was denied.
We are glad that our attorneys' efforts were able to help the client in pursuing its IP rights, and actually the above-mentioned second-instance case was commended as one of the 50 exemplary cases of IP judicial protection in China of 2012. Likewise, we believe that this supreme court ruling, which touched upon the determination of whether inventiveness ground falls within the scope of obvious substantive defect as well as PRB's ex-officio examination in practice, should also serve as important reference for patent applicants in facing similar issues in future.
