A new feature of IPEXL.com that they have opened up is the ability to do proximity searching. (Largely inspired by Chris Jagalla's Post on Intellogist's Blog)
So let's say you wish to search patents with the words: battery, walk and floor that are two words away from each other anywhere in the abstract. Users can use the following search string:
"battery walk floor"~2
The same can be used for searching in fields too. So if you wish to search for patents by inventor "George Boyd" then you can also pick up "George H Boyd" and variants of his name by using the proximity search like so:
Another Example could be the search for patents by the attorney Frederick J Telecky:
ATN:("Frederick J Telecky Jr") returns 8,288 results.
ATN:("Frederick Telecky"~1) returns 8,346 results.
The same applies to IPEXL trademark search too. For example:
TXT:("coca cola"~1) vs TXT:("coca cola")
Give it a try yourself over at IPEXL.com.
