What worries me is Bounce Exchange company has a patent to display popup when user leaves window.
Use action in the form of movement of a tracking device on a webpage, represented by cursor gestures on the webpage, is used to detect it a user intends to leave the webpage. Upon detection of an intent to leave the webpage, an advertisement may be displayed to a use.
Do you think I can use the solution mentioned inside Stackoverflow for displaying popup? The solution also uses cursor gestures to track exit intend. But it doesn't say anything about displaying popup. So that worries me because Bounce Exchange claims to have a patent of using similar solution to display popup.
