A federal judge has agreed to hear on Dec. 7 Heartland Payment Systems Inc.'s request for a preliminary injunction barring VeriFone Holdings Inc. from soliciting the processor's merchant clients that use VeriFone's terminals.
VeriFone is recommending that Heartland merchants using its equipment register to receive technical support from the terminal maker after Dec. 31, when VeriFone has said it will stop providing Heartland with support.
Heartland contends that it can continue to support its customers' terminals without VeriFone's help.
The two companies are suing each other over a disagreement stemming from Heartland's development of an advanced encryption terminal.
VeriFone, of San Jose, alleges that Heartland's terminal design infringes on one of its patents; Heartland, of Princeton, N.J., claims VeriFone is engaging in unfair trade practices.
A U.S. district court judge in New Jersey turned down last week Heartland's request for a temporary restraining order that would have forced VeriFone to shut down the Web site it is using to enroll Heartland's customers in its service program.
