NOTES:
1) Even though some of the patent authorities (above) have slightly different names (not actually called a "Patent office," per say) we call them that for simplicity of page layout and ease of use (on this page, only). 
2) One asterisk (*)  means that documents from at least one other patent authority may be found at the web site.
3) Two asterisks (**) mean that patents or documents from several countries may be found at the site. 
4) Two plus signs (++) means that Free registration is required in order to search.
5) The links should take you to the English versions of the web sites. If not, or you find a link that has become stale, please drop us a "quick" note to Support(at)IPDataCorp.com - Thanks!
