Are Amiga patents being used by other companies?

If they do own the patent for bootable CDs I wouldn't be surprised. The CDTV was released in 1991 and this was even before the days of the "powerful multimedia systems" (IE a PC with a SoundBlaster and a CD-ROM).

Hey look at this :-)
It must be the "right mouse button" patent discussed earlier?

Abstract

Menu item selection is performed in a personal computer system through the use of a mouse device which has means to allow the user to call up onto the display a header block which performs the function of the menu bar and to erase the header block from the screen when menu operations are not required. Multiple menu items can be selected during the same menu session by using a pair of mouse buttons to generate a sequence of selection commands which are utilized by unique system software to accumulate plural item selections without terminating the menu operation.
