In the judgment Ref. No. 104-Pan-Zi-No. 326, the Supreme Administrative Court held that a party requesting patent invalidation may combine all or part of the 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 requesting the invalidation should bear the burden of proving the important technical features combined for invalidating the invention at issue, and such burden of proof cannot be exempted by reason of claiming “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”, and it also erred in finding facts that are not based on specific evidence. Therefore the judgment was insufficient in law. The Supreme Administrative Court vacated the IP Court’s judgement and remanded the case to the IP Court for further proceeding.
