The judges will respond to motions from the defendants to transfer, but in this district Judges Everingham and Ward default to favoring the plaintiff's choice and have consistenly applied a stringent test to those requests. Only if the defendants can show by predefined factors that their proposed venue is "clearly more convenient" than the venue chosen by the plaintiff will they allow a transfer (here's a blog that tracks the court's activity).
The judges don't seem to mind the extra load. In fact they pride themselves how their "streamlining" of the process for trying patent cases has drawn in so much activity. They've fondly nicknamed their court "the rocket docket".
