US Patent 11374990 Saving an overlay annotation in association with a shared document

Methods, systems, and computer program products for integrating content management systems with web conferencing facilities. An overlay annotation generated via a web conferencing facility is associated with a content object of a content management system. Integration code at the web conferencing facility displays a portion of the content object of the content management system. As user generates an overlay annotation during the web conferencing session while the content object is displayed in an interaction window of the web conferencing facility. After the overlay annotation has been captured, the content management system receives the overlay annotation from the web conferencing facility and stores the overlay annotation in an annotation content object separate from the content object of the content management system. Registrations and other associations between the overlay annotation object and the content object itself are stored for either or both of the overlay annotation object and the content object.
