均等論的判斷

筆記

Graver Tank & Mfg. Co. v. Linde Air Products Co., 339 U.S. 605 (1950)

這個1950年的美國最高法院判例涉及均等論的判斷方法,也就是確立常見的Function, Way, Result的判斷依據。

美國專利US2,043,960,為一個電子焊接的技術,以及相關的熔劑。


判例決定的重點:

均等論的適用在於,如果兩個裝置以"實質相同"的方法(way)做相同的工作,並達成"實質相同"的結果(result),表示這兩個裝置即便有不同的名稱(name)、形式(form)或是形狀(shape),但判斷為相同的東西。
The doctrine of equivalents is founded on the theory that, if two devices do the same work in substantially the same way and accomplish substantially the same result, they are the same, even though they differ in name, form or shape.

在判斷均等條件時,應考慮專利中成份的目的、與其他成份組合的特性、欲產生的功效,以及判斷是否該領域技術人員可以知道有任何該專利中未出現而可以取代的成份。
In determining equivalents, consideration must be given to the purpose for which an ingredient is used in a patent, the qualities it has when combined with other ingredients, the functions which it is intended to perform, and whether persons reasonably skilled in the art would have known of the interchangeability of an ingredient not contained in the patent with one that was.
