In a new Southern District of California complaint, Taction Technology, Inc. has accused Apple (3:21-cv-00812) of infringing two patents—generally related to a device for “imparting motion on to the skin of a user” by delivering electrical currents to magnets enclosed in a housing—through the provision of certain Apple Watch and iPhone products that feature its Taptic Engine haptic implementation. The patents name S. James Biggs, Taction’s founder and CTO, as their sole inventor.
