Caltech( California Institute of Technology) has filed a lawsuit against Apple and Broadcom over WiFi patents.  The WiFi technology is used in many of the Apple products including the iPhone 5

Is Caltech taking the que from University of Wisconson, Madison, having won a $200 million patent infringement case against Apple? Perhaps.  Caltech claims the violation of four patents by Apple and Broadcom.

The protocols manage encoding and decoding circuitry to enable faster data transmission in the 802.11n and 802.11ac Wi-Fi standards, that incorporate these IRA/LDPC encoders and/or decoders and thereby infringe upon the four asserted patents in question

Now it is up to Apple and Broadcom to provide proof or perhaps they will settle?

Apple uses Broadcom chips in the Apple Watch, iPhones, and iPads, as well as its line of Macs that support 802.11ac, including the MacBook Air, Retina MacBook Pro, and iMac.

The lawsuit could halt the sale of many Apple products.

The asserted patents include U.S. Patent No. 7,116,710, U.S. Patent No. 7,421,032, U.S. Patent No. 7,916,781, and U.S. Patent No. 8,284,833.
