Abstract： [Purposes] This paper aims to analyze whether "obviousness" meets the standard of "implicit disclosure"，and whether "direct and unambiguous derivation" can replace "implicit disclosure"，so as to provide reference for determining whether amendments to invention patents exced the scope.[Methods] Starting from the latest judgment of the European Unified Patent Court and typical domestic court rulings，this paper elaborates on the diferences between "implicit disclosure" and "obviousness"，as well as the analysis of substituting the "implicit disclosure" standard with "directlyand unambiguously derived" under the legislative intent of Article 33 of the Patent Law.[Findings] The study concludes that amended technical solutions deemed "obvious" fail to meet the non-extension requirement for patent amendments.While the "directly and unambiguously derived" standard represents a valuable analytical approach，it diffrs fundamentally from the "implicit disclosure" criterion and may inappropriately introduce "obviousness" considerations into the amendment assessment process.[Conclusions] From the legislative purpose of balancing the interests between patent applicants and the public，any analytical approach that conforms to the original meaning of "directly and unambiguously determined" from the perspective of a person skilled in the art should be permissble.This conclusion aims to provide references for determining whether patent amendments exceed the original scope.
