US Patent 11588913 Push notification management

A push notification mechanism at a mobile user device provides for automated limiting of the rate of production of push notification alerts (such as an audible alert or a vibratory alert) and/or push notifications responsive to the occurrence of chat events relevant to a chat application hosted by the user device. Some chat events automatically trigger suppression periods during which push notification alerts are prevented for subsequent chat events that satisfy predefined suppression criteria. Such push notification and/or alert limiting can be performed separately for separate users, chat groups, and/or chat event types.
