IPA Technologies Inc., a subsidiary of Quarterhill Inc. (f/k/a Wi-LAN Inc.), has stipulated to the transfer of another case out of District of Delaware to the Southern District of California in light of the US Supreme Court’s TC Heartland case on proper venue in patent cases. In June, IPA agreed to move its March 2017 case against Kyocera to the Southern District, and now in September, it has done the same in its case against ZTE (3:17-cv-01858). This additional transfer comes as the court considers multiple motions challenging the patents asserted, broadly related to speech recognition technology, as patent-ineligibly directed to the abstract idea of “responding to a spoken request” under Alice. IPA opposed the motions by touting parallel development of Apple’s digital assistant Siri, identifying the alleged technical aspects of the recited claims, and contending that claim construction is required to decide the pending motions.
