Rates Technology Inc. based in Hauppauge, N.Y., filed suit against Google in a New York federal court in October, alleging that Google Talk illegally uses its technology for billing people for phone calls made over Internet connections.
Google Talk is the search giants combination of instant messaging and VOIP (voice over IP).
Google said in a statement Wednesday, "We believe the lawsuit is without merit and we will defend against it vigorously."
The Web site Search Engine Watch reported upon the suit this week.
U.S. District Judge E. Thomas Boyle last heard the case on Dec. 6.
Neither Boyles clerk nor attorneys representing Rates Technology responded Wednesday to requests for comment.
