預料不到的技術效果在發明創造性評判中的關聯性考量

Relevance Consideration on Unexpected Technical Effects in In-ventive Step of Patent

“預料不到的技術效果”並非創造性評判中一個獨立的考慮因素，“預料不到的技術效果”，其本質上是發明客觀上獲得的技術效果，在創造性“三步法”的評判中應當作發明客觀產生的技術效果予以考慮，將預料不到的技術效果當作發明客觀產生的技術效果中的一種因子在“三步法”的使用中予以考量，而不將其獨立於“三步法”的判斷進行單獨考量，符合專利法第二十二條第三款的法律邏輯，這樣的評判方式也更為合理和有效。在將預料不到的技術效果納入“三步法”判斷中進行考量時，應將區別技術手段、所應用的技術領域、所解決的技術問題、相應實現的技術效果，這四個方面當做一個有機的整體進行綜合化考量，從而得出更為合理的評判結論。

Unexpected technical effect' is not a separate consideration factor in inventive step of Patent, however it is essentially the objective technical effect obtained by the invention, and should be considered as objective technical effect obtained by the invention in 'three-step' determination method. Considering unexpected technical effects as objective technical effect obtained by the invention in 'three-step' determination method, rather than separately considering without 'three-step' determination method, meets the legal logic of Article 22 (3) ofthe Patent law, and is more reasonable and effective manner of judgment. As unexpected technical effect is considered into 'three-step' determination method, four aspects of distinguishing technical means, applied technical field, technical problem to be solved and corresponding technical effect, should be taken into an organic comprehensive consideration to arrive at a more reasonable conclusion in inventive step.
