IBM is escalating its legal battle with Zillow, filing a second lawsuit accusing the listings giant of infringing on patents to build its real estate search engine.
In a July 21 lawsuit, filed in federal court in Washington, IBM claimed the Seattle-based company infringed on five patents that improve searches by ranking results and simplifying content displays, among other things. Despite written notifications, Zillow has engaged in a “policy of willful blindness” and continues to use the technology, IBM alleges.
