M。P。E。P。2701:
A patent granted on an international application filed on or after June 8, 1995 and which enters the national stage under 35 U.S.C. 371 will have a term which ends twenty years from the filing date of the international application. A continuation or a continuation-in-part application claiming benefit under 35 U.S.C. 365(c) of an international application filed under 35 U.S.C. 363 designating the United States will have a term which ends twenty years from the filing date of the parent international application.
因此你我说的两种情况都是PCT filing date 开始的20年。
不过提醒了我,主贴里的保护时间只针对实用专利和植物专利,外观专利(design)的保护时间为批准日开始的14年 |
