Classic Amiga patents...

[Chas916]

I did a search at the US Pattent Office website and found 17 pattents registered to Commodore Business Machines. I grabbed one of those and it was submitted in 1988

United States Patent      5,088,035
Gardei ,   et al.    February 11, 1992
System for accelerating execution of program instructions by a microprocessor

I didn't see any patents for datatypes though.

I also found some pattents for Commodore-Amiga Inc files by RJ Mical.

I'm not sure Apple would like this Patent:

United States Patent      4,772,882
Mical    September 20, 1988
Cursor controller user interface system

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.
