Broadcom, Apple sueballed

Caltech has lobbed a sueball at Apple and Broadcom over its Wi-Fi patents.

The case, 2:16-cv-03714-GW-JPR in the Central District Court of California, alleges breaches of US patents 7,116,710, 7,421,032, 7,916,781 and 8,284,833.

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. ®
