美國專利法第102(g)條

102(g)所規定的為一般新穎性原則，是除了有其他人已經完成發明之外，還要公開揭露，並無拋棄或是隱藏的事情，其中共有兩段：

原文：
§102. Conditions for patentability; novelty and loss of right to patent
A person shall be entitled to a patent unless--
(g)(1)
during the course of an interference conducted under section 135 [35 USC 135，專利審查中的爭議] or section 291 [35 USC 291，專利權人間的民事訴訟], another inventor involved therein establishes, to the extent permitted in section 104 [35 USC 104，有關發生在美國境外的發明], that before such person's invention thereof the invention was made by such other inventor and not abandoned, suppressed, or concealed,

(g)(1)專利申請人在發明之前，於專利法135或 291中所規範的干擾期間內，並在專利法104條的允許之下，若有其他發明人有並未拋棄、隱匿的相同發明時，本發明不能准予專利

102(g)(2)
before such person's invention thereof, the invention was made in this country by another inventor who had not abandoned, suppressed, or concealed it. In determining priority of invention under this subsection, there shall be considered not only the respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one who was first to conceive and last to reduce to practice, from a time prior to conception by the other.

(g)(2)在發明之前，在本國(美國)之外有其他發明人有未拋棄或是隱匿的相同發明時，該發明的優先順序的考量並不只有在概念與付諸實現的日期，也要考量他人先有構想但晚付諸實現的努力。


若要引用美國專利法第102(g)條的規定核駁一件申請案，通常要考量在申請人完成發明之前的其他發明有：

1. 形成明確的概念(conception)
2. 真正付諸實現(reduction to practice)，並能工作於意欲的目的
3. 積極地付諸實現，也就是要提出申請，所以審查意見中，常引用之前專利或專利公開案
4. 要付出努力(diligence)
