Some common browser functions are covered by the patents. One patent, for example, is for making suggestions to consumers based on what they're looking at on their displays or, in the case of social networks, based on what others on the network are viewing. The others govern letting the reader of a news story discover material related to subjects in the story and the display of information or multimedia outside a viewer's main focus on the screen.
