On the market for an iPhone? Here's a breakdown of all the currently shipping iPhones from Apple.
Caltech Accuses Apple of Violating its Patented Wi-Fi Technologies
Caltech's patents, granted between 2006 and 2012, are highly technical and relate to IRA/LDPC codes that utilize simpler encoding and decoding circuitry for improved data transmission rates and performance. The technologies are implemented in both the 802.11n and 802.11ac Wi-Fi standards used by many Apple products.
In the court filing with the U.S. District Court for Central California, Caltech accused Apple of selling various iPhone, iPad, Mac, and Apple Watch models, along with other Wi-Fi products, that incorporate these IRA/LDPC encoders and/or decoders and thereby infringe upon the four asserted patents in question.
Apple manufactures, uses, imports, offers for sale, and/or sells Wi-Fi products that incorporate IRA/LDPC encoders and/or decoders and infringe the Asserted Patents. Apple products that incorporate IRA/LDPC encoders and/or decoders and infringe the Asserted Patents include, but are not limited to, the following: iPhone SE, iPhone 6s, iPhone 6s Plus, iPhone 6, iPhone 6 Plus, iPhone 5c, iPhone 5s, iPhone 5, iPad Air, iPad Air 2, iPad Pro, iPad Mini 4, iPad Mini 3, iPad Mini 2, MacBook Air [and] Apple Watch.Apple has at least temporarily pulled stock of its AirPort Extreme and Time Capsule Wi-Fi base stations from its U.S. stores, but it's unclear if the move is related.
Broadcom, as one of Apple's main suppliers of Wi-Fi chips, is also named in the complaint. Apple currently 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.
Apple is one of Broadcom's largest customers. In 2012, 2013 and 2014, sales to Apple represented 14.6%, 13.3% and 14.0% of Broadcom Corp.'s net revenue, respectively. […] During this timeframe, Broadcom's Wi-Fi products that incorporate IRA/LDPC encoders and decoders and infringe the Asserted Patents were incorporated into Apple's key products including iPhones, iPads, and Mac computers. […] Broadcom and Apple are jointly and severally liable for infringement of the Asserted Patents.Caltech has demanded a jury trial against Apple and Broadcom, along with a preliminary and permanent sales injunction in the U.S. against the aforementioned products. The university also seeks "adequate" damages, and other relief that the court deems "just and equitable," but it did not provide a specific settlement target.
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.
