Re: Patent Searching - with Keywords

Subject: Re: Re: Patent Searching - with Keywords

Comments:
: The EPO search engine has a collection of over 30 million patent documents from all over the world, including the European countries, the U.S., Japan, Australia, Canada, and Korea. All U.S. patents (1790 to the present) are now accessible from the US patent office database. : For the "keyword patent searching online" system to work well, one primary (or strong) reference needs to be found using keywords, either from the EPO patent search engine or the US patent search engine. The searcher is then able to find other patents that are linked to the primary reference - much as an academic researcher finds other references through bibliographies. : Technical research is hard work, whether the research is in the patent databases, academic databases, or applied technical publications. : If you're searching for a needle in a haystack - one reference from the beginning of time, patent or nonpatent, filed anywhere in the world, in any language, the job is most difficult with any and all systems (in combination), and with an army of professional searchers. : I hope this helps. : --Gerald R. Black
