US Patent 10171579 Managing presence among devices accessing shared and synchronized content

A content management system receives presence information from a client application on a device indicating interaction information of a user relative to a content item synchronized to the content management system. The interaction information includes presence information describing presence information of a native application interacting with the content item. The presence information indicates whether the native application opened, is viewing, or is editing the content item. The presence information may specify a user interface element and process associated with the presence information. The content management system stores presence records describing the presence information and uses the presence records to generate and transmit a presence status associated with a user. When a new version of a content item is received, the content management system may also use the presence records to determine an action to perform with the user interface window associated with the prior version.
