In the United States, Touchtone was a registered trademark of AT&T. I'm
not sure when they gave it up; it may have been at the time of the
divestiture. A query of the trademark database reveals seven current
registered trademarks incorporating the word touchtone:

        Touchtone Invest
        Fidelity Touchtone Xpress
        Touchtone Xpress
        Touchtone Jobsline
        Touchtone Rentsline
        Touchtone Transportation
        Touchtone Trader

The last of these was the earliest filed, on March 26, 1992, so I think
it's a safe bet that AT&T gave up the trademark before that date.

In some countries Touchtone is still a trademark of the applicable telephone
company or agency. For example, in the UK it is a registered trademark of
British Telecommunications PLC:
