美国的专利法律状态检索
前面有同学发了这个帖子
按照这个帖子
先找到网站:
http://portal.uspto.gov/external/portal/pair
再找到Patents Official Gazette项
点Search Patents & Applications
在右列的
Patent Number输入PPT中的实例专利号US6659017
结果确是显示:
Sorry, patent \"US6659017\" cannot be retrieved as entered. Please re-enter the patent number in an alternate
format: Utility \"9,999,999\" or \"9999999\", Design \"D999,999\" or \"D999999\", Plant \"P9,999\" or \"P9999\",
Reissue \"RE99,999\" or \"RE99999\", Def. Pub. \"T999,999\" or \"T999999\", SIR \"H9,999\" or \"H9999\", or try a
new search.
怎么会出现这么个结果?
我要查美国专利还有什么办法吗?
谢谢! |
