專利進步性之判斷(一)—美國判例於進步性之原則— 專利工程師 / 陳詠容
Discretion of whether such patent has useful improvement to the existing solution (1) – improvement to the existing solution principles in Taiwan - Patent Engineer Yung-Zhong Chen
一、前言 Preamble
新穎性、進步性與產業可利用性為取得專利權之三大要件,發明欲取得專利權需同時兼具該三要素。然而綜觀專利行政爭訟與民事訴訟之案例,不難發現近期與進步性相關的爭議佔了絕大部份之比例。本文分作四篇,前兩篇先帶讀者了解美國判例對於進步性所建立出之判斷準則,接著檢視該準則與我國現行專利法與專利審查基準對於進步性判斷基準之異同,最後探討我國實務判決之判定標準。
The issue of novelty, improvement to the existing solution, and industrial usefulness are the three main requirements to gain its patent right. By looking at the patent administrative litigation and civil litigation case studies, it is not hard to find that there are more topics focuses on its controversial issues of improvement to the existing solution principles. This article would be divided into four parts; the first two articles would lead our reader to understand how the America’s case study can influence on its discretion of whether its patent has useful improvement to the existing solution, followed by examining its judicial reasoning by comparing our current patent examination procedure. Lastly, we will discuss Taiwan’s case judgements and its criteria standards.
二、美國判例於進步性之原則
America’s case implications on its improvement to the existing solution principles
美國對於進步性之判斷,早已豎立了TSM檢測法,即教示(Teaching)、建議(Suggestion)及動機(Motivation)。而1966年美國最高法院於Graham v. John Deere Co.[1]案(以下簡稱「Graham案」)提出進步性分析原則[2]:(1) 確定先前技術之範圍與內容;(2) 確定先前技術與有爭議之專利範圍請求項間之區別;(3) 確定相關領域一般技術之水準。如經此三步驟判斷出爭議專利範圍請求項係其所屬領域中具通常知識者可輕易完成者,則該發明則為顯而易見,惟仍須同時考量爭議之專利範圍是否有商業上成功、解決長期未解決之問題、或他人皆無法成功發明等次要衡量因素。然而,TSM檢測法在美國實務運作卻產生引證資料只限於明示,且忽略所屬技術領域中具有通常知識者之角色等問題[3]。
In terms of America’s discretion of whether such patent has useful improvement to the existing solution, there is implications on the TSM test and concepts including teaching, suggestion and motivation. In the case of Graham v John Deere Co (1996), (“Graham” case) list out all the elements when determining whether its application has improvement to the existing solution on principles. This includes: (1) confirm the claims and the drawings of the application; (2) confirm its prior art and the disputed claims and the drawings of the current application; (3) confirm relevant skills in the relevant field. Once we determine the three steps in terms of its patent dispute range that an ordinary person can be easily accomplished, such patent would be treated as ‘obvious to try’ and its case would be treated as invalid. However examiner should also need to balance and to take other factors into account such as how wide is its patent claiming and whether there is any business success, long term problem solving solutions or others inventions that cannot be easily accomplished by an ordinary person. However by looking at the implications of the TSM test, it only included ‘obvious to try’ principle in practice but neglected to look at its technology field problems for which an ordinary person would have.
