California Institute of Technology (Caltech) has added a case against Samsung (2:21-cv-00446) to the litigation campaign that saw a large infringement verdict against Apple and Broadcom in January of this year. The university again asserts the same five patents in suit against the other three defendants in active district court cases: Dell, HP, and Microsoft. Caltech targets Samsung over the provision of various “Wi-Fi products” (e.g., computers, refrigerators, smartphones, smart watches, tablets, TVs, etc.) that are compliant with certain Wi-Fi standards (802.11n, 802.11ac, and/or 802.11ax) and the 12 low-density parity-check (LDPC) error correction codes incorporated in those standards.
