The Federal Circuit Court of Appeals has affirmed a lower court decision holding that the patent infringement asserted against MarketLinx, a business unit of CoreLogic, was invalid.
The multiple listing service system patent infringement claim filed in Austin, Texas, by CollegeNET Inc. in 2009 was ruled without merit by both the state and federal courts.
Reached on June 19, the federal court’s decision agreed with conclusion reached by the United States District Court for the Western District of Texas.
CollegeNET claimed that several CoreLogic MarketLinx products, including the MLXchange, TEMPO and Fusion multiple listing service systems, “infringed on a CollegeNET patent” designed to deliver automatic notifications when data entered into a database match predefined search criteria.
CollegeNET owns U.S. Patent No. 6,910,045, a computer software that sends such automatic multiple listing service related notifications.
In November 2011, the state court’s summary judgment stated that CollegeNET’s patent claims were invalid as obvious.
In June the federal circuit “affirmed without opinion” leaving the district court’s judgment in place and thus concluding the CollegeNET patent is invalid.
