There are two new features available in Espacenet.
The new extftxt field identifier lets you perform full-text searches for keywords anywhere in a patent document (title, abstract, description and claims). To perform a full-text search in Smart search, run a normal search (step 1). By default, the search is run in the bibliographic data collection. Click Refine search (step 2) to be able to select one of the three full-text searchable collections available and run your search again (step 3).
Espacenet lets you search for partners residing in countries that could be of interest for your business or research field. In Advanced search, just enter a country code between square brackets, e.g. [CN], in the Inventor(s) or Applicant(s) field. In Smart search, use the following query: in=[CC] or pa=[CC], e.g. pa=[JP].
