Other software and services that purportedly violate Interval's patents include Apple's iTunes music store, App Store, Apple TV and Ping social networking service; Google's search, its AdSense targeted text advertisements, and its Talk, Reader and Gmail software; Facebook's "Like" and "News Feed" features; Netflix's TV and movie recommendations; and Yahoo Connected TV and Widgets.

Interval has asked that Pechman bar the companies from further infringement -- which, if granted, might require the firms to shutter the named services and stop distributing the identified software until changes were made -- and that the defendants be required to pay damages to be decided by a jury.
