If a defendant did not respond (and assuming there has been no settlement), why would eDig want or be obligated to dismiss "with prejudice" preventing them from re-visiting the issue in the future?

The only way it seems to make sense is that either:

a) It was discovered that there was no infringement / no reason for eDig to pursue further.

b) A settlement was reached without a formal response to the court.

Are there any other reasons this may occur? How about Plankton, any thoughts?
