Zillow Sues Trulia Over Home Valuations
September 17, 2012
Zillow has filed a lawsuit against Trulia, alleging that Trulia infringed on a patent it has for its Zestimate software, a home valuation tool.
Zillow says its patent includes a process for providing home valuations for its “Zestimates” that allows home owners to submit updated data online to be used in the valuations. In the lawsuit, Zillow alleges that Trulia, one of its chief rivals, is using the same process for its home valuation estimates. Since September 2011, Trulia Estimates has allowed owners of the properties to provide input on the properties in order to improve the accuracy of its real estate valuations.
Zillow says it has a patent filed with the U.S. Patent and Trademark Office for its home valuation processes system.
Trulia has declined to comment publicly about the pending lawsuit.
Meanwhile, Zillow alleges that the patent infringement has caused “damage to Zillow.”
