The Delaware federal district court is enlisting the help of four visiting judges from the U.S. District Court of the Eastern District of Pennsylvania to manage the caseload of an outgoing judge, as it braces for a large wave of patent cases that appears to be headed in its direction.

Judges Mitchell Goldberg, Gerald McHugh, Mark Kearney and Senior Judge Eduardo Robreno are expected to pick up the caseload of Judge Sue L. Robinson, who has taken senior status and plans to retire from the U.S. District Court for the District of Delaware this summer.
