Russ August & Kabat won reversal of a summary judgment order that found no infringement of patents owned by client, Mirror Worlds Technologies, LLC, which were asserted against Facebook, Inc. in the United States District Court for the Southern District of New York. The appeal was argued at the Federal Circuit by Russ August & Kabat attorney Marc A. Fenster.
The Federal Circuit agreed with Mirror Worlds that the District Court erroneously concluded that, based on the evidence in the record, there was no genuine dispute about Facebook’s infringement of the patents. Though Facebook submitted declarations and testimony from key engineers about its systems, the Federal Circuit determined that there was sufficient evidence to support a jury verdict that Facebook’s accused systems infringe Mirror Worlds’ patents.
The patents at issue are U.S. Patent Nos. 6,006,227, 7,865,538 and 8,255,439, which are related to managing and organizing information into time-ordered streams. Because the Federal Circuit reversed the District Court’s summary judgment order, the case has been returned to the District Court, where Mirror Worlds’ claims of infringement will proceed.
Mirror Worlds is represented by Russ August & Kabat attorneys Marc A. Fenster, Benjamin T. Wang, James Tsuei, and Theresa Troupson.
