If I do search in both windows, I will miss patents which have no IPC or EPC codes So I had to do searches on EPC and after EPC codes In this case, the search can found patents like this one IPC (4 Digits) : H05K; C09J; IPC (All Digits) : H05K3/46; C09J7/02; C09J177/00; H05K3/38; ECLA (All Digits) : H05K3/38D; Is there another solution _________________ Best regards Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Matheo Software Forum Index -> Matheo Patent Page 1 of 1, All times are GMT Post new topic    Reply to topic   Jump to: Select a forum General----------------Announcements Download Section----------------Latest versions of all our software Discussions, Comments and uses of our software----------------Matheo PatentMatheo AnalyzerMatheo Web Resources----------------Internet resources for Matheo WebPublications, Articles, Thesis, ...Internet resourcesNewsletters  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB Group © 2001,2005.
