No, the first modem with an AT command set was the Hayes Smartmodem 
(300bps).  However, what you might be thinking of is the patent on 
the "+++" escape sequence itself (WITHOUT guard times) which had 
been granted to Bizcomp.  This patent was eventually declared 
invalid in a trial, but the Hayes patent (which "built on" the 
Bizcomp patent with the guard time) was upheld.  Hayes did license 
the Bizcomp patent when it was first granted, but (of course) we 
don't pay royalties on it now.
