Apple told Reuters that it plans to appeal, having previously said that it was merely a “downstream party” because it didn’t develop the chips, but merely purchased them from Broadcom. The technology is vital to the 802.11n and 802.11ac WiFi standards, though its inventor said that the patents (related to data transmission tech), weren’t originally designed for WiFi.

Broadcom remains a major Apple supplier, having recently signed a $15 billion agreement to furnish chips for upcoming iPhones and other products. It remains to be seen if CalTech will go after other device manufacturers, but told Reuters that it is “committed to protecting its intellectual property in furtherance of its mission to expand human knowledge.”
