Patently Apple:

The California Institute of Technology has filed a patent infringement lawsuit against Broadcom and Apple (and Avago Technologies owned by Broadcom). The patent infringement lawsuit concerns Apple’s iPhones beginning with the iPhone 5, the iPad, MacBook Air, Apple Watch and more. Apple’s use of Broadcom’s technology is using IRA/LDPC encoders and/or decoders invented by the California Institute of Technology. In this lawsuit, Apple is drawn in by virtue of using Broadcom Wi-Fi products.

And:

This week AirPort Extreme and Time Capsule were pulled from U.S. Apple Stores. Whether this is due to next-gen versions of these product arriving next month or complications related to this lawsuit is unknown at this time.

Interesting.
