Flexsys 是 US 5,117,063 ( ‘063 專利 ) 和 US 5,608,111 ( ‘111 專利 ) 的專利權人。 其中 ‘111 專利是 ‘063 專利的部分延續案。在此兩案有爭議的內容實質相同。 Flexsys 於 2005 年 2 月 23 號在 ITC 主張 Sinorgchem 侵害其 ‘063 專利和 ‘111 專利,並違反 section 337 。 Sinorgchem 主要從中國生產並進口至美國一種物質,稱為 6 PPD ,而 Flexsys 的兩篇專利正是此種物質的生產方式。
以 ‘063 專利 claim 61 為代表,本案唯一爭議點在於步驟 (b) 中針對 “controlled amount” 一詞的 claim construction 。Copyright © 2007 All rights reserved.

- A claim term will not receive its ordinary meaning if the patentee acted as his own lexicographer and clearly set forth a definition of the disputed term in … the specification …, Vitronics Corp. v. Conceptronics, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)
- A “controlled amount” of protic material is an amount up to that which inhibits the reaction of aniline with nitrobenzene, e.g., up to about 4% H2O based on the volume of the reaction mixture when aniline is utilized as the solvent.
- A patent claim should be construed to encompass at least one disclosed embodiment in the written description portion of the patent specification.
- a presumption that each claim in a patent has a different scope.
