Microsoft wants patent on adware

The application, filed in 2006, describes a multi-faceted, robust ad-delivering system that lives on a "user computer, whether it's part of the OS, an application or integrated within applications."

"Applications, tools, or utilities may use an application program interface to report context data tags such as key words or other information that may be used to target advertisements," says the filing. "The advertising framework may host several components for receiving and processing the context data, refining the data, requesting advertisements from an advertising supplier, for receiving and forwarding advertisements to a display client for presentation, and for providing data back to the advertising supplier."

The adware framework would leave almost no data untouched in its quest to sell you stuff. It would inspect "user document files, user e-mail files, user music files, downloaded podcasts, computer settings, computer status messages (e.g., a low memory status or low printer ink)," and more. How could we have been so blind as to not see the marketing value in computer status messages?

The software would also free advertising from its traditional browser yoke. "A word processor may display a banner ad along the top of a window, similar to a toolbar, while a graphical ad may be displayed in a frame associated with the application. A digital editor for photos or movies may support video-based advertisements," the patent application says.
