Some trademark attributions still say Novell (or even AT&T or Bell Labs), which is correct?

UNIX^® is a registered trademark of The Open Group.

Please see The Open Group Legal Pages for the latest information here.

The correct attribution is:

"UNIX is a registered trademark of The Open Group"

Some licenses (which date from before the merger of X/Open Company with The Open Group) still require the following attribution:

"UNIX is a registered trademark in the United States and other countries, licensed exclusively through X/Open Company Ltd."

All licenses will be updated in due course; in the meantime, The Open Group is happy for either attribution to be used. Any other attribution is incorrect.

The Trademark Usage Guide is available in postscript or PDF formats. This guide describes the rules for use of X/Open Company trademarks. It is designed to be a practical guide. Of itself, this guide does not grant permission to use any trademark.

Please note:

• It must not be used as a generic term.
• It must not be used in connection with products, unless the product is licensed to use the mark.
• There are detailed guidelines referring to the visual presentation, form and manner of use.
• In editorial or articles, but not advertising the trade marks may be used without prior permission - provided that the rules in our Trademark Usage Guide are followed.

Motif, OSF/1, and UNIX are registered trademarks and IT DialTone, the X device and The Open Group are trademarks of The Open Group.
