    The maintenance fee for Apparatus for regulating transmission power of repeater in long term evolution system (US 9,231,689) comes due Jul 5, 2027. Unpaid by Jan 5, 2028, it lapses early.

US patent applications published under this name that have not become patents. An application is published about eighteen months after its earliest filing; one that has not been published is in no public record.
