Analysis of information sources in references of the Wikipedia article "Threshold of originality" in English language version.
To qualify as a work of 'authorship' a work must be created by a human being.... Works that do not satisfy this requirement are not copyrightable. The Office will not register works produced by nature, animals, or plants.
實務上,法院於判定是否為「著作」時,常以「原創性」之有無為依據,並將「原創性」再區隔為「原始性」及「創作性」,此或係受到美國著作權法第101條定義"original works"中之"original"用語之影響……我國法院對於「原創性」有無之判斷,常會因刑事案件或民事案件而有不同標準。在刑事案件,為避免被告未授權之利用而罹犯刑章,法院多採較嚴格之標準,儘可能讓著作不受著作權法保護,以有利於被告
However, according to established case law, the courts have said that copyright can only subsist in subject matter that is original in the sense that it is the author's own 'intellectual creation'. Given this criterion, it seems unlikely that what is merely a retouched, digitised image of an older work can be considered as 'original'. This is because there will generally be minimal scope for a creator to exercise free and creative choices if their aim is simply to make a faithful reproduction of an existing work.
「創作性」,並不必達於前無古人之地步,僅依社會通念,該著作與前已存在之作品有可資區別,足以表現著作人之個性為已足
只要具有最低程度的創意,可認為作者的精神作用已達到相當程度,足以表現其個性或獨特性,即可給予保護
判決稱:「查卷附劉桂榮取得著作權之『加官晉祿圖』﹑『祥龍戲珠圖』﹑『彩鳳獻瑞圖』等三種圖樣﹐與我國民間流傳認為吉祥象徵之龍﹑鳳及神像造形並無何個性或獨特性之差別﹐其是否為原創性之美術創作﹐不無疑義。」依此判決之文義觀之﹐創作性之高度並非討論之重心﹐而係逕以個性或獨特性為原創性之內容。
