TT "Q" Dumb Question

[Don Muirhead <dmr@kwic.com>]

Thanks to those who responded and advised me that the TT Quattro isn't a 
true Quattro system but a Haldex system.  I checked and read <yawwwn> what 
I could on the Haldex system and have concluded that the Haldex is an apple 
to orange and not an apple to apple "q" comparison.

So my dumb question is...then why is the car called an Audi TT Quattro?  Is 
Quattro a Registered Trade Name (yes) an active Patented System (don't no) 
or both?  Keyword being Patent...
