Question

An invention may be granted a patent upon application, except for the invention was publicly known prior to the filing of the patent application. Which requirement for patent is contained in this description?
(A) Patentable subject matter
(B) Inventive step
(C) Enablement
(D) Novelty

Accepted Answer

正確答案為 D。 專利三要件之一：新穎性 (Novelty) 要求發明在申請前未被公開。 (A) Patentable subject matter 指「可專利標的」，討論發明是否屬於法律允許的專利客體 (如抽象概念、自然法則不可專利)，與是否公開無關。 (B) Inventive step (進步性/非顯而易見性) 指發明對該領域技術人員而言不能是顯而易知的。雖也與先前技術比對，但重點在「創造高度」，不是「是否公開」。
