In the judgment Ref. No. 104-Pan-Zi-No. 326, the Supreme Administrative Court held that a party petitioning patent invalidation may combine all or part of technical features disclosed in multiple citations and state the reasons of such combination in order to claim that the invention at issue lacks inventive step. The party petitioning the invalidation should bear the burden of proving the important technical features combined in the disclosed citations for invalidating the invention at issue, and such burden of proof cannot be exempted by the reason of claiming asserting “conventional technique”. Therefore, the IP Court erred in ruling that “the technical features which are not disclosed by the citations are just the conventional technique” because that its establishment of fact failed to rely on specific evidences therefore the judgment was in violation of the law. The Supreme Administrative Court vacated the IP Court’s judgement and remanded the case to the IP Court for further review.
