\"为什么US5846996不按照“申请日+20年<授权日+17”年的取长原则计算呢?\"
因为美国授权专利US5846996虽是一个继续申请(continuing application),但它的申请日(1997年10月14日)是在1995年6月8日之后, 因而符合MPEP 如下规定:
CONTINUING APPLICATIONS
A patent granted on a continuation, divisional, or continuation-in-part application that was filed on or after June 8, 1995, will have a term which ends twenty years from the filing date of earliest application for which a benefit is claimed under 35 U.S.C. 120, 121, or 365(c), regardless of whether the application for which a benefit is claimed under 35 U.S.C. 120, 121, or 365(c) was filed prior to June 8, 1995.\"
如果一件美国专利其申请日在1995年6月8日之前, 则“申请日+20年<授权日+17”年的取长原则计算适用.
