Apple has been sued by Lionra Technologies LTD for patent infringement. Lionra is owned by Atlantic IP, a major patent troll headquartered in Dublin Ireland. They're suing Apple using HP patent 7,779,267 titled "Method And Apparatus For using a Secret in a Distributed Computing System."

The patented invention has particular relevance to use of security tokens, for example smart cards, within distributed computing systems, and in particular to methods and apparatus for effective use of secrets retained within or provided by such security tokens.

In this case, Lionra claims that Apple's Secure Enclave infringes an HP patent that they legally acquired for the sole purpose of suing companies, with Apple being its largest target.  

According to the formal complaint filed by Lionra Technologies, "Apple makes, uses, offers for sale, sells, and/or imports certain products that contain the Secure Enclave and/or support Apple Pay, including without limitation iPhone 6, 6 plus, 6S, 6S Plus, SE (first and second generation), 7, 7 Plus, 8, 8 Plus, X, XR, XS, XS Max, 11,11 Pro, 11 Pro Max, 12, 12 mini, 12 Pro, 12 Pro Max, 13, 13 mini, 13 Pro, 13 Pro Max, 14, 14Plus, 14 Pro, 14 Pro Max, Watch Series 1, Watch Series 2, Watch Series 3, Watch Series 4, Watch Series 5, Watch SE, Watch Series 6, Watch Series 7, Watch Series 8, Watch Ultra, Watch SE (second generation), iPad Air (or later), MacBook Pro computers with Touch Bar (2016 and 2017) 4 that contain the Apple T1 Chip, Intel-based Mac computers that contain the Apple T2 Security Chip, and Mac computers with Apple silicon (the “Accused Products”), that infringe, literally and/or under the doctrine of equivalents, one or more claims of the ’267 Patent. Identification of the accused products will be provided in Plaintiff’s infringement contentions pursuant to the Court’s scheduling order. "

Lionra's complaint further adds that "Apple continues to actively encourage and instruct its customers and end users (for example, through user manuals and online instruction materials on its website and materials cited in Exhibit 6) to use the Accused Products in ways that directly infringe the ’267 Patent. For example, Apple advertises the secure features of Apple Pay [as presented below]:

Later they add: "Apple provides these instructions, user manuals, and other materials knowing and intending (or with willful blindness to the fact) that its customers and end users will commit these infringing acts."

Lionra Technologies is seeking "compulsory ongoing licensing fees," as determined by the Court in equity, and more.
