RPX recently noted the transfer of nine US patents from South Korean research institution Electronics and Telecommunications Research Institute (ETRI) to KAIFI LLC, a Texas plaintiff that has previously litigated a single patent originating with Korea Advanced Institute of Science and Technology (KAIST) but received from Intellectual Discovery Co., Ltd. That assignment is now sandwiched between a July 2023 transfer from PowerVoice to KAIFI (three patents) and an April 2024 transfer from Intellectual Discovery (one patent). This past week, KAIFI sued Amazon (2:24-cv-00542) over its received assets, in a new Eastern District of Texas complaint that targets the provision of a wide array of products, including the Alexa voice assistant and related products.
