Caltech Files Original Complaint Against Microsoft, Amended Complaints Against Dell, HP

March 20, 2021

Late last week, California Institute of Technology (Caltech) filed three new complaints in the litigation campaign that resulted in an infringement verdict awarding $1.1B in damages—$837.8M against Apple and $270.2M against Broadcom—in January 2020. One of the complaints is original, asserting five patents against Microsoft (6:21-cv-00276), three tried to the California jury, one at issue in the early days of this campaign, and one new to the litigation. Caltech amended its complaints in November 2020 cases filed against Dell and HP such that all five error-correction coding patents are now asserted against each active defendant. The accused products throughout have been various computer products (e.g., laptops, tablets, thin clients, workstations, etc.) that comply with certain Wi-Fi standards (802.11n, 802.11ac, and/or 802.11ax), targeted for the 12 low-density parity-check (LDPC) codes incorporated in those standards.
