Alert Signal Intellectual Property, LLC (Alert Signal IP), an apparent affiliate of inventor Fred DuFresne and/or his monetization firms Cerinet USA Inc. and ipCapital Licensing Company (d/b/a Cerinet IP Licensing), has filed suit in the Eastern District of Texas against Apple (2:18-cv-00177). All members of a four-patent family are asserted in the new complaint, which targets iPhones running iOS 11 or above, alleging infringement through aspects of its Do Not Disturb feature that disable alerts when the user is driving by detecting the phone’s physical velocity (“Do Not Disturb While Driving” mode) and that allow priority messages to trigger alerts.
