What it covers
This patent describes a centralized system that collects data from browser cookies across multiple visitors and stores it in a central repository. A website administrator uses a special interface to define 'custom segments' by picking specific cookie parameters (like a product category) and setting logical relationships such as 'equals' or 'contains.' When a new visitor arrives, the system checks their cookies against these rules. If the data matches a segment, the system automatically serves the pre-selected content, such as a specific banner ad, to that user.
What it doesn't cover
- —Does not cover tracking users across different devices or browsers using fingerprinting techniques.
- —Does not cover real-time bidding exchanges where ad inventory is auctioned to the highest bidder.
- —Does not cover server-side session management that does not involve user-defined segment rules.
- —Does not cover privacy-preserving technologies that block or anonymize cookie data collection.
The clever bit
The innovation lies in the administrative interface that allows non-technical marketers to define complex logic ('contains', 'approximates') for cookie data, effectively turning raw browser data into actionable marketing segments on the fly.
Why it matters
This patent represents the infrastructure behind the personalized web experience common in the 2010s. It provided a framework for marketers to move away from generic advertising toward granular, data-driven content delivery without needing deep programming knowledge.
