The EPO recently announced that US assignment data will be updated weekly instead of bimonthly in the INPADOC legal status database, which also means that it will be available via esp@cenet.
The data will be captured from the USPTO's assignment database one week after it is posted.
This is a much appreciated improvement. It will save searchers a lot of time switching back and forth between esp@cenet/INPADOC and the USPTO database.
