Inventor-controlled DH International Ltd. has filed separate Western District of Texas cases against Alphabet (Google) (1:23-cv-01116) and Apple (1:23-cv-01114) over the respective provision of the Apple Pay and Google Pay mobile payment platforms, as well as related hardware. The two patents-in-suit are generally related to a “portable electronic device” that, upon detection of an external cue, will initiate a data exchange, and if not, will communicate information to a user instead. Both were asserted—by a different but associated plaintiff—against Samsung in an Eastern District of Texas suit that ran from October 2020 through August 2021.
