The patents will be used protection as the company defends itself from a new lawsuit brought by Yahoo.
USAT says the patents cover "technologies dealing with software and networking."
Yahoo recently sued Facebook over patent infringement, claiming the social networking giant infringed on up to 10 patents relating to advertising, privacy controls and social networking. Facebook rejected the claims and says it will defend itself in court.
Both IBM and Facebook declined comment on the purchase.
