法院:CAFC 美國聯邦巡迴上訴法院 (Fed. Cir. 2008)
日期:2007/1/29
原告:TRIMED, Incorporated. (上訴人)
被告:Stryker Corporation (被上訴人)
系爭專利: US 5,931,839
相關規範: Claim Construction; Means plus function
Trimed 是 美國專利 US 5,931,839 ( ‘839 專利) 的專利權人, ‘839 專利是關於一種固定骨折的骨頭之器具。 Trimed 在中加州地方法院對 Stryker 提起專利訴訟,主張 Stryker 生產的骨頭固定器侵害其專利。
在 claim construction 的時候, Stryker 主張 ‘839 專利之獨立項有出現 means plus function 。 Stryker 因此提出 motion for summary judgment ,主張 1) 該 means plus function 語言中,需要有醫生的參與才能達到其功能性語言; 2) 被控侵權的產品只存在 holes ,但是專利權利中則須包含 holes + some other structures ,因此, Stryker 沒有侵害 ‘839 專利。Claim 1 有關 means + function 的部分如下:
- said holes in said plate providing means for allowing the pin to slide axially therein but preventing compression across the fracture, and stabilizing said near end of the pin against displacement in the plane of the plate.
- Use of the word “means” in claim language creates a presumption that 112(6) applies.
- If, in addition to the word “means” and the functional language, the claim recites sufficient structure for performing the described functions in their entirety, the presumption of 112(6) is overcome – the limitation is not a means-plus-function limitation.
- The fact that a particular mechanism . . . is defined in functional terms is not sufficient to convert a claim element containing that term into a “means for performing a specified function” within the meaning of section 112(6).
- Sufficient structure exists when the claim language specifies the exact structure that performs the functions in question without need to resort to other portions of the specification or extrinsic evidence for an adequate understanding of the structure.
