一件有關發明人不實的案例筆記 - Jaswant S. PANNU v. IOLAB CORPORATION (CAFC 1998)

剛好有需要討論inventorship,在此筆記一下涉及102(f)的1998年案例 - 發明人確實才能主張專利權。


案件資訊:
原告/被上訴人/專利權人:JASWANT S. PANNU and JASWANT S. PANNU, M.D., P.A.
被告/上訴人:IOLAB CORPORATION
系爭專利:Re32,525
判決日:August 06, 1998


本案緣起Jaswant向地方法院對Iolab提起侵權告訴,Iolab提起專利無效(35 U.S.C. §102(f))的請願,但地院判決專利有效,Iolab對此決定提起上訴。

102(f):
A person shall be entitled to a patent unless -
...
(f) he did not himself invent the subject matter sought to be patented.

系爭專利有些歷史,簡單來說,專利權人魚1980年提出專利申請案,之後提出CIP案,到了1985年提出再領證(reissue),即本次系爭專利。


專利權人於1993年向Iolab提出侵權告訴,但Iolab提起請願,主張專利無效,理由是Pannu不是系爭專利的唯一發明人,還有William Link,另主張系爭專利並未揭示best mode,違反112規定。

地院判決是專利有效,沒有違反112規定,且侵權成立。

CAFC階段:

主要議題關於inventorship,Iolab主張系爭專利不符102(f)無效,因為沒有將William Link列在發明人中,甚至主張William Link才是唯一發明人,因為Pannu的發明已經是本次系爭專利的先前技術

事實上,發明人是可以更正的,可參考以下案例參考連結,

但案件經上訴CAFC後,CAFC同意Iolab的主張 - Pannu不是唯一發明人,據此也根據旁系禁反言,不得主張專利權。

CAFC在此判決是:
The district court properly construed the disputed claim terms and did not err in denying the post-trial motions challenging the infringement and non-infringement verdicts.   However, the court did err by granting JMOL on the issue of inventorship.   Iolab introduced sufficient evidence on which a reasonable jury could have found clear and convincing evidence that Link is a co-inventor.   On such a finding and absent correction, the patent would be rendered invalid under section 102(f).   Accordingly, we vacate the judgment in favor of Pannu and remand for a determination of the inventorship question and any related issues in a manner not inconsistent with this opinion.

後續CAFC曾經有再確認的決定August 8, 2001

關於發明人是誰?

依照Iolab提出的證據,CAFC認為Iolab對,但也沒全對,同意Pannu與Link為共同發明人,理由是,William Link也沒主張自己是唯一發明人,且Pannu也向他揭示了發明的概念,Pannu對發明有貢獻。

如此,在沒有更正發明人時,根據102(f),CAFC判決系爭專利是無效的,撤銷地院判決被告須繳付雙方律師費用的決定,還以"旁系禁反言(collateral estoppel)"防止Jaswant繼續主張Re32,525專利權。
