Did You Know that Zillow Sued Trulia?

In an 18-page ruling issued Oct. 7, Judge James L. Robart of the federal court Western District in Washington state stayed the case pending a decision by the Patent and Trademark Appeal Board of the U.S. Patent and Trademark Office. The appeals board has been asked to consider Trulia’s claim that real estate valuation is a “covered business method” and thus can’t be patented.

I have no idea whether the Zestimates are proprietary, but I do know that in Dallas they are mostly just wrong. The case has produced more than 128,000 pages of Discovery. How very, very green!
