Status update: Facebook defriends Yahoo, countersues for patent infringement
Remember last month’s post about Yahoo suing Facebook for infringement of 10 of its patents? It hasn’t taken Facebook long to strike back. Last week, the social networking giant brought a counterclaim in the US District Court in San Francisco in which it denies Yahoo’s claims and accuses Yahoo of violating 10 of its patents, including patents for displaying advertising, privacy and photo sharing.
