Facebook won a patent for generating a personalized feed of stories for users, quite similar to the news feed-related patent the company was awarded earlier this year. For example, compare the following excerpts from the abstracts of the first and the second patent: “generating dynamic relationship-based content†versus “generating news items regarding activities associated with a user of a social network.†So far, Facebook has been using its patents defensively, and hasn’t sued other companies that have features similar to Facebook’s news feed. However, merely controlling these patents gives Facebook even more power over its competitors in the social networking realm.
