Displaying Friends' Activities in a Social Network Feed

This patent describes how social networks like Facebook collect what users do, create short updates about those actions, and show them to specific friends in a personalized list called a "news feed."

What it covers

The patent describes a system that monitors various user activities within a social network, such as posting a photo or updating a status (Claim 1). These activities are stored in a database and then used to generate "news items" (Claim 1). For instance, if a friend shares a link, a news item is created about that action. These news items are then displayed in a "news feed" to a specific group of viewing users, with access limited by privacy settings (Claim 1). Crucially, each news item can include a link that allows the viewing user to "participate in the same activity" as the original user, such as clicking to comment on a shared post (Claim 1). The system can also arrange these items, for example, chronologically (Claim 6), and dynamically adjust the number of items shown (Claim 12).

What it doesn't cover

• —Does not cover displaying news items without an associated link that allows a viewing user to participate in the same activity (Claim 1).
• —Does not cover news feeds that are not limited to a "predetermined set of viewers" (Claim 1).
• —Does not cover systems where news items are not generated from activities performed by *another user* (Claim 1).
• —Does not cover news feeds that only show a single news item, as it specifies "two or more" (Claim 1).
• —Does not cover news feeds that don't monitor and store user activities in a database (Claim 1).

The clever bit

The novelty lies in combining the monitoring of diverse user activities, generating news items from them, and then dynamically displaying these items in a personalized, access-controlled feed that includes interactive links. The ability to link directly to the *same activity* for participation was a key innovation.

Why it matters

This patent covers the foundational functionality of the Facebook News Feed, a feature that profoundly changed how people interact on social media. Launched in 2006, the News Feed became central to Facebook's user engagement and growth, allowing users to passively consume updates from their network. Its success led to widespread adoption of similar feed-based interfaces across the internet and remains a core component of modern social platforms.
