If the court concurs, Facebook&nbsp;could be left wide-open in settlement negotiations, and might have to pay Yahoo a hefty sum of cash and/or stock. Specifically, the old web portal&nbsp;claims&nbsp;that after it sued for patent infringement, Facebook bought patents&nbsp;'for purposes of retaliation'. </p><p>Therefore they don't meet the U.S. Patent Office's 'Duty of Disclosure, Candor, and Good Faith'&nbsp;and should be thrown out of Facebook's countersuit against Yahoo. Yahoo also claims Facebook broke their agreement to inform each other of IP issues, couldn't legally know if Yahoo was violating its patents, and that several of Facebook's new patents were illegally filed. Finally, Yahoo filed two more advertising patent infringement claims against Facebook that look to be quite incriminating. Here's breakdown of the five claims and how they'll influence the outcome of the case.</p>
