Pulling hair with Patent Search
« on: Jul 21st, 2006, 7:28pm »

I am searching for patents whose assignees consisting of names of more than 1 word.  For example, I want to search for a company called 'Big Boy', but always the search engine (http://ep.espacenet.com/ or uspto) always gives me more results than what I want.  I try using double quotes "Big Boy" but it still gives me the combination of the two words.  It appears the default is 'or' rather than 'and' between the words in the query.
 
Any help is greatly appreciated.

In the USPTO simple search, you would type "big" as the term for field 1 and select "Assignee Name" as the field type and type "boy" as the term for field 2 and select "Assignee Name" as the field type.  Be sure the pull-down menu between the two fields is selected as "AND."
 
When you click "Search", you'll see that your complete search string is "AN/big AND AN/boy".  If you're clever, you can extrapolate from there and add more words to the assign name or try different names.
 
I hope that helps.
 
Regards.

Actually on the USPTO I believe the correct search string that samo is looking for is AN/"Big Boy" , (AN/big AND AN/boy) will make for a broader search that isn't necessary if you are looking for a company named "big boy." I only turn up a single document meeting the criteria, and it was issued in 1972. You won't find it unless you change the USPTO's default search settings to search patents from 1790+ instead of 1976+

As far as esp@cenet is concerned, here you go:

Apparently, on esp@cenet you can search US patents pre-1970 in fields beyond number and classification - news to me.
