2021年7月,聯邦地院根據字辭典的定義,認為「擴大的(enlarged)」是一個具有相對、比較意義的「程度上術語」(Terms of Degree),而需要有比較的基礎才能讓PHOSITA合理推知所謂「擴大的空間(enlarged chamber)」到底有多大。基於Grace未在系爭專利中提供PHOSITA所需的客觀界線,因此同意系爭專利不符明確性要件。

本案中附隨的爭點包含解釋專利請求項4中「means for driving said rotor to rotate located in at least one bottom section,」之解釋,因受限於篇幅ˋ,建議有興趣的讀者可以從判決原文中學習解釋專利申請項及其範圍。
Grace, 2023 U.S. App. LEXIS 17. (“The district court erred in its reliance on extrinsic evidence—i.e., dictionary definitions—that contradict the scope and meaning of ‘enlarged chamber’ that a skilled artisan would ascertain by reading the intrinsic record.”.”)
Id., at 14-15.
Id., at 18. (“even when guidance is not provided in explicit definitional format, the specification may define claim terms by implication such that the meaning may be found in or ascertained by a reading of the patent documents.”)
