Third-party funded Active Wireless Technologies LLC has filed suit over four wireless communications patents from a portfolio received from FG Innovation Company Ltd. (f/k/a FG IP Innovation Company Ltd.) (FGI) this past March. Deutsche Telekom (T-Mobile) (2:23-cv-00261) is accused of infringement through the provision of cellular networks that implement Narrowband-IoT (NB-IoT) technologies, as well as related products, with compliance with various 3GPP standards at issue throughout. FGI has farmed out batches of patents to five NPEs, four of which have now filed litigation over the received assets in the US.
