Is Little Red Riding Hood a patent of IBM?

Trackpoint is the patent of thinkpad on IBM notebook. Other companies such as Dell and Hewlett-Packard also have devices similar to Little Red Riding Hood. But the color is definitely not red. HP's is a little blue hat, and Dell's is a little green hat. . . And the sensitivity is not as high as that of Little Red Riding Hood. O(∩_∩)O~
