Fellowship Filtering Technologies, LLC has added two new cases to its only litigation campaign, filing suit against Alibaba and Taobao Software (2:15-cv-02049) and Yandex (2:15-cv-02062) in the Eastern District of Texas. The suits assert the same patent (5,884,282) that has been in litigation from the outset of this campaign in May 2015. The ‘282 patent is related to an automated collaborative filtering (ACF) system for making recommendations based on user-generated data. Fellowship Filtering has targeted websites and suppliers of collaborative product recommendation software from the beginning, including Adobe, Baidu, Callidus Software, eHarmony, HP, IAC (match.com), IBM, NetSuite, Oracle, Salesforce, SAP, and TIBCO.
