US Patent 9742833 Document sharing through browser

Presenters are enabled to broadcast a document to remote viewers from one browser to another. While viewing a document in the web browser, a user can share the document out to remote viewers by providing them with a link that when selected, opens the document synchronously with the presenter in web browser. The viewers are enabled to consume the broadcast by watching the presenter go through the document in real time. The viewers may also be enabled to view the document asynchronously from the presenter and easily synchronize back with the presenter's view.
