Broadcom, Apple sueballed
Caltech has lobbed a sueball at Apple and Broadcom over its Wi-Fi patents.
The focus of the patents is error correction used in 802.11n and 802.11ac – in particular, IRA/LDPC encoders in Broadcom chips (IRA – irregular repeat and accumulate codes; LDPC – low-density parity check).
Broadcom is the first defendant in the case, with Apple named because it's using Broadcom chips; Apple products named in the case include iPhone 5 and later, iPad, MacBook Air and Apple Watch. ®
