The patent wars are a hot mess. Maybe this infographic can help you sort things out...
The patent wars have gotten uglier and more numerous as time rolls on. It’s now nearly impossible to keep track of who is accusing who of infringing on what anymore.
It all makes a little more sense in diagram form. Visual.ly has done the service of compiling some of the numbers involved in the patent wars and has released an infographic on the skirmishes that each of the companies are involved in. You can see that Apple, ZTE, Huawei, Kodak, and Microsoft are all bearing the brunt of the worst of it.
Samsung and Apple have recently been in talks to settle their differences. Google and Oracle just settled their patent lawsuit yesterday. Maybe in time we can start seeing this diagram clear up a little?
