Google Threw A Punch, Microsoft Fires Back With A Missile
That does not mean anything. Yes MS may have asked Google to partner with them to buy the patents but no-one knows what the terms were. A good attorney can make an agreement that allows Google to be sued on the patents even if they are co-owners. Or the agreement may say that any Android phone manufacturer can be sued on the patents by Microsoft, and Google does not have the power to give those manufacturers licenses.So an undisclosed offer made in private does not mean much. If Microsoft had made their offer public they may use it to make a point, but as things stand now this supposed offer is best ignored.PS: I should also note that this "we made them a generous offer and they refused" statement is a trick often used by PR people and politicians to muddy the water.
