The core of the dispute involves Optis's claims that Apple infringed on five of its standard-essential patents (SEPs) related to LTE technology, used in iPhones, iPads, and Watches. The court vacated earlier judgments on infringement and damages, mandating a new trial due to a non-unanimous jury verdict on infringement and the improper inclusion of an Apple-Qualcomm settlement agreement as evidence for damages. Additionally, the court reversed previous rulings regarding the patent eligibility of certain claims and the interpretation of another claim, while affirming a different claim construction, ultimately remanding the case for further proceedings.
