ArvinMeritor prevails in transmission technology dispute

ArvinMeritor, Inc. announced today that the U.S. Patent Board of Appeals and Patent Interferences has issued judgment in ArvinMeritor's favor against Eaton Corporation on all claims in two related transmission patent interferences.

An interference is a court-like proceeding in the Patent Office to determine who was first to make an invention. Under U.S. law, the first to invent is deemed the owner of the patent. The decision was rendered on April 29, 2004.

"This is another significant legal victory for ArvinMeritor and our second successful defense against Eaton's legal assaults on our transmission business," said Tom Gosnell, president of ArvinMeritor's Commercial Vehicle Systems business group. "Eaton's unsuccessful effort to seize our torque prediction patent further validates our position as the technology leader in this product. As we've said repeatedly, we'll continue to aggressively defend all of our product technology."

The interferences involved an ArvinMeritor U.S. patent on torque prediction technology. Torque prediction is an enabling technology for some automated transmissions.
