Touch Tone Trademark Status [telecom]

Lisa Hancock asked in a reply:

According to the US Patent and Trademark Office website search, it was officially cancelled due to "total surrender" by the (legacy) holder of the trademark (AT&T), on 13-March-1984. Note that this is shortly after the official start of divestiture (01-January-1984), some 27+ years ago.

See the following entry at the USPTO's webiste:

also, the wikipedia entry for DTMF (Dual-Tone Multi-Frequency) mentions that AT&T's trademark registration for "Touch Tone" ended on 13-March-1983, as well as the website Trademarkia at the following page:

I don't know offhand, but I wouldn't at all be surprised if several long-time Bell System/AT&T trademarks or service marks were cancelled or abandoned or surrendered or otherwise not renewed, during the early years of post-divestiture, shortly after 01-Jan-1984.
