I believe the parent company is Yamazaki. They use Mitsubishi in their 
controls.

It's Zamak in the US, and Mazak in the UK (possibly Europe too?) and other 
parts of the world. I'm in the other parts of the world bit.

In USA, copyright and trademark are handled by two different departments.

Copyright registration is handled by Library of Congress.  Although 
registration is not required, in the event of an infringement suit, it 
makes the copyright largely uncontestable, rendering THAT part of the suit 
moot.


Trademark is handled by the Patent And Trademark Office.  Registration is 
advisable.  But even an unregistered trademark, if well documented, can be 
used to show "prior use", to defend in a suit, or to contest a new 
registration.


Many trademarks have entered common usage, such as "kleenex" for facial 
tissue, or "Xerox", and are rather diluted, although still not available 
for competitors to use.


In 1987, while doing some business at PTO (Patent and Trademark), I 
confirmed that "MS-DOS" was trademarked, whereas "PC-DOS was NOT 
trademarked.  IBM considered it to be a description of the product, not 
the NAME.  Similarly, you would not be able to trademark "DOS" due to 
extensive prior use.


I don't know the details of what happened when Concurrent CP/M-86 was 
briefly marketed as "Concurrent PC-DOS".



OB_Disclaimer: IANAL (I Am Not A Lawyer), although I did costume as one on 
Halloween one year.

I thought it was Mazak too - eg

I had those exact same original Mazak handwheel dials on my ML7, changed them 
out for the machined resettable ones from Myford. Much nicer!
