content: Microsoft has a habit of filing patents for things that already exist. Then getting the patent approved. For example IBM had a patent for a file system on a floppy drive, then Microsoft modified it and called it FAT (File Allocation Table) and then filed a patent for it and go approved and then sued anyone who used FAT support in Linux like the Tomtom GPS system on SDcards. Everything Xerox and Apple patented for the GUI, Microsoft took and made Windows and then filed a patent for Windows and got approved.  This is obviously a slide to unlock bar just like the iPhone has had for a long time.
