First off, companies use patents that already existed all the time. Thats news to you, welcome to the world of knowing wtf your talking about :shake:
2ndly, the patent was for consoles. Your still talking about PC while being stuck on stupid.
Finally, while the result is the same. The patent is on how it gets to that result. So Microsofts patent I believe stopped consoles from doing cross game chat from a game level. Cross game chat on the PS4 is built in from the system level so that doesn't violate the patent Microsoft made.
Smart right? But how did Microsoft know sony would need that? Simple. Thats how the Xbox worked. Then they made it so it was built into the Xbox 360's design and put out that good patent which blocked sony from trying to steal the idea and use it on there system. Moving to this next gen sony is once again behind the curve on this stuff and guess what microsoft has a patent on this gen?
