Yahoo is not having a good week
“Below I examine in detail the meaning of each of the patents Facebook is countersuing with, and compare their validity with the Yahoo’s claims. In all but one patent category, privacy, Facebook’s either has the upper hand or stands on near equal footing. If Yahoo does infringe on Facebook’s patents, it may have been making millions of dollars a year in ad revenue thanks to improved ad targeting, and increased engagement from Flickr photo tagging and news site home page content relevance. Those could turn into damages awarded to Facebook or offset the money Facebook made from infringing on Yahoo’s patents.
Whether the cases go to trial or private negotiation, Facebook might walk away clean. Even if Yahoo does come away with a settlement, the whole debacle won’t have been nearly as lucrative as if Facebook hadn’t countersued. Meanwhile, no matter the outcome, Yahoo hangs its head in shame.”
